Item 1. Reports to Stockholders.

The registrant's annual report transmitted to shareholders pursuant to Rule 30e-1 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), is as follows:

We thank you for your investment in the Guggenheim Credit Allocation Fund (the “Fund”). This report covers the Fund’s performance for the 12-month period ended May 31, 2021.

The recovery from the COVID-19 outbreak has been faster than many expected. Consumer confidence has held up well as massive fiscal support drove positive personal income growth and a swift monetary policy response led to gains in household net worth. While fiscal support and COVID-19 vaccines continue to be deployed, disruptions in the economy and markets caused by the COVID-19 pandemic may materially impact the Fund and its assets.

To learn more about the Fund’s performance and investment strategy, we encourage you to read the Economic and Market Overview and the Questions & Answers sections of this report, which begin on page 5. There you will find information on Guggenheim’s investment philosophy, views on the economy and market environment, and detailed information about the factors that impacted the Fund’s performance.

The Fund’s investment objective is to seek total return through a combination of current income and capital appreciation.

Under normal market conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities, debt securities, loans and investments with economic characteristics similar to fixed-income securities, debt securities and loans (collectively, “credit securities”). The Fund seeks to achieve its investment objective by investing in a portfolio of credit securities selected from a variety of sectors and credit qualities. The Fund may invest in credit securities of any duration or maturity. Credit securities in which the Fund may invest may pay fixed or variable rates of interest. The Fund may invest without limitation in securities of non-U.S. issuers, including issuers in emerging markets.

All Fund returns cited—whether based on net asset value (“NAV”) or market price—assume the reinvestment of all distributions. For the 12-month period ended May 31, 2021, the Fund provided a total return based on market price of 43.05% and a total return based on NAV of 28.67%. As of May 31, 2021, the Fund’s market price of $21.27 per share represented a premium of 12.18% to its NAV of $18.96 per share.

Past performance is not a guarantee of future results. All NAV returns include the deduction of management fees, operating expenses, and all other Fund expenses. The market price of the Fund’s shares fluctuates from time to time, and may be higher or lower than the Fund’s NAV.

From June 2020 through May 2021, the Fund paid a monthly distribution of $0.1813 per share. The most recent distribution represents an annualized distribution rate of 10.23% based on the Fund’s closing market price of $21.27 per share on May 31, 2021. There is no guarantee of any future distribution or that the current returns and distribution rate will be maintained. The Fund’s distribution rate is not constant and the amount of distributions, when declared by the Fund’s Board of Trustees, is subject to

^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT} l ³

change based on the performance of the Fund. There is no guarantee of any future distribution or that the current returns and distribution rate will be maintained. Please see the Distributions to Shareholders & Annualized Distribution Rate on page 24, and Note 2(f) on page 53 for more information on distributions for the period.

Guggenheim Funds Investment Advisors, LLC (the “Adviser”) serves as the investment adviser to the Fund. Guggenheim Partners Investment Management, LLC (“GPIM” or the “Sub-Adviser”) serves as the Fund’s investment sub-adviser and is responsible for the management of the Fund’s portfolio of investments. Each of the Adviser and the Sub-Adviser is an affiliate of Guggenheim Partners, LLC (“Guggenheim”), a global diversified financial services firm.

We encourage shareholders to consider the opportunity to reinvest their distributions from the Fund through the Dividend Reinvestment Plan (“DRIP”), which is described in detail on page 83 of this report. When shares trade at a discount to NAV, the DRIP takes advantage of the discount by reinvesting the monthly distribution in common shares of the Fund purchased in the market at a price less than NAV. Conversely, when the market price of the Fund’s common shares is at a premium above NAV, the DRIP reinvests participants’ distributions in newly issued common shares at the greater of NAV per share or 95% of the market price per share. The DRIP provides a cost-effective means to accumulate additional shares and enjoy the benefits of compounding returns over time. Since the Fund endeavors to maintain a stable monthly distribution, the DRIP effectively provides an income averaging technique, which causes shareholders to accumulate a larger number of Fund shares when the market price is depressed than when the price is higher.

We appreciate your investment and look forward to serving your investment needs in the future. For the most up-to-date information on your investment, please visit the Fund’s website at guggenheiminvestments.com/ggm.

Sincerely,

Guggenheim Funds Investment Advisors, LLC

The Treasury yield curve steepened in the 12 months ending May 31, 2021, as investors reacted to inflationary fears and uncertainty about the stability of the economic recovery and the direction of future Federal Reserve (the “Fed”) policy. During that time, the yield on the two-year Treasury declined by 2 basis points (“bps”) to 0.14 from 0.16, and the 10-year U.S. Treasury climbed 93 bps to 1.58% from 0.65%. The spread between the two-year Treasury and 10-year Treasury widened from 49 bps to 144 bps. One basis point is equal to one-hundredth of one percent, or 0.01%.

U.S. economic growth picked up in the first half of 2021 as new COVID-19 cases subsided and fiscal policy gained traction. First quarter real gross domestic product (“GDP”) increased by a robust 6.4% annualized, and we expect growth could accelerate to 11% annualized in the second quarter as the COVID-19 vaccine rollout and looser state restrictions allow for greater services spending. Personal consumption should continue to power growth, as households are flush with cash due to the past year’s pandemic-related spending constraints, record fiscal transfers, and surging equity and real estate valuations.

The combination of recovering demand and lingering supply constraints is leading to price increases across a range of goods and services despite the prevalence of excess capacity in many sectors. This apparent contradiction can also be seen in the labor market data: The unemployment rate remains elevated at 5.8%—and the labor force participation rate is 1.8% below its pre-pandemic peak—but a record share of small business owners report difficulty in finding workers. We expect these pandemic-induced supply constraints and associated price pressures to be transitory, as do Fed officials who will discount the noisy inflation data in coming months. Our analysis suggests that the secular disinflationary headwinds of the past few decades will prove more lasting than a rise in prices due to temporary supply shortages.

Against this backdrop we expect Fed policymakers will defer the tapering of the Fed’s $120 billion in monthly asset purchases until 2022, which would also push back the timing of the first rate hike. Another potentially dovish variable is that President Biden will have an opportunity to appoint up to four new Fed governors in the next seven months, including a new chair. We expect an emphasis on diverse candidates whose professional focus skews toward labor market inequality. This would underscore the Fed’s new commitment to a “broad based and inclusive” interpretation of its maximum employment mandate, and could result in low rates for longer.

The economy’s ability to fully recover from the pandemic depends in large part on the success of the global vaccination campaign. While the U.S. is on track to inoculate over 60% of the population later this year, vaccination drives outside of the U.S. are progressing more slowly, especially in lower-income countries with large populations. Many of these are reliant on traditional vaccine technologies that deliver lower protection rates. As a result, the world economy faces sharply divergent growth prospects, which will likely limit the Fed’s ability to hike rates as soon as markets are pricing (25 bps by January 2023) without triggering a disruptive rise in the dollar. The upshot is we expect that real U.S. interest rates will remain deeply negative, providing a risk-friendly backdrop for investors.

Guggenheim Credit Allocation Fund (the “Fund”) is managed by a team of seasoned professionals at Guggenheim Partners Investment Management, LLC (“GPIM”). This team includes B. Scott Minerd, Chairman of Guggenheim Investments and Global Chief Investment Officer; Anne B. Walsh, CFA, JD, Senior Managing Director and Chief Investment Officer, Fixed Income; Thomas J. Hauser, Senior Managing Director and Portfolio Manager; and Richard de Wet, Director and Portfolio Manager. In the following interview, the investment team discusses the market environment and the Fund’s performance for the 12-month period ended May 31, 2021.

What is the Fund’s investment objective and how is it pursued?

The Fund’s investment objective is to seek total return through a combination of current income and capital appreciation. Under normal market conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities, debt securities, loans and investments with economic characteristics similar to fixed-income securities, debt securities and loans (collectively, “credit securities”). Credit securities in which the Fund may invest consist of corporate bonds, loans and loan participations, asset-backed securities (all or a portion of which may consist of collateralized loan obligations), mortgage-backed securities (both residential mortgage-backed securities and commercial mortgage-backed securities), U.S. Government and agency securities, mezzanine and preferred securities, convertible securities, commercial paper, municipal securities and sovereign government and supranational debt securities. The Fund will seek to achieve its investment objective by investing in a portfolio of credit securities selected from a variety of sectors and credit qualities. The Fund may invest in credit securities that are rated below investment grade (commonly referred to as “high-yield” or “junk” bonds), or, if unrated, determined to be of comparable credit quality. The Fund may invest in credit securities of any duration or maturity. Credit securities in which the Fund may invest may pay fixed or variable rates of interest. The Fund may invest without limitation in securities of non-U.S. issuers, including issuers in emerging markets.

The Fund may, but is not required to, use various derivatives for hedging and risk management purposes, to facilitate portfolio management and to earn income or enhance total return. The Fund may use such transactions as a means to synthetically implement the Fund’s investment strategies. In addition, as an alternative to holding investments directly, the Fund may also obtain investment exposure by investing in other investment companies. To the extent that the Fund invests in synthetic investments with economic characteristics similar to credit securities, the value of such investments will be counted as credit securities for purposes of the Fund’s policy of investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in credit securities (the “80% Policy”).

The Fund may invest in open-end funds, closed-end funds and exchange-traded funds. For purposes of the Fund’s 80% Policy, the Fund will include its investments in other investment companies that have a policy of investing at least 80% of their net assets, plus the amount of any borrowings for investment purposes, in one or more types of credit securities.

⁶ l ^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT}

The Fund uses financial leverage (borrowing and reverse repurchase agreements) to finance the purchase of additional securities. Although financial leverage may create an opportunity for increased return for shareholders, it also results in additional risks and can magnify the effect of any losses. There is no assurance that the strategy will be successful. If income and gains on securities purchased with the financial leverage proceeds are greater than the cost of the financial leverage, common shareholders’ return will be greater than if financial leverage had not been used. Conversely, if the income or gains from the securities purchased with the proceeds of financial leverage are less than the cost of financial leverage, common shareholders’ return will be less than if financial leverage had not been used.

What are the details of the Guggenheim closed-end fund merger announcement made on April 20, 2021?

Guggenheim Investments announced that the Boards of Trustees of each of Guggenheim Strategic Opportunities Fund (NYSE: GOF), Guggenheim Enhanced Equity Income Fund (NYSE: GPM) and Guggenheim Credit Allocation Fund (NYSE: GGM), each a closed-end fund (each, a “Fund” and together, the “Funds”), approved the mergers of GPM and GGM with and into GOF. GOF would be the acquiring Fund, and the acquired Funds would be GPM and GGM.

The proposed mergers are intended to provide potential benefits to common shareholders, including exposure for GPM and GGM to the enhanced investment opportunities offered by GOF, economies of scale and greater secondary market liquidity for each Fund’s common shareholders, among other things. Upon closing of the mergers, GOF would continue to be subject to its current investment objectives, policies and restrictions.

It is currently expected that the mergers will be completed in the third or fourth quarter of 2021, subject to required shareholder approvals and the satisfaction of applicable regulatory requirements and other customary closing conditions. Shareholders of GPM and GGM would receive newly issued common shares of GOF, the aggregate net asset value (not the market value) of which will equal the aggregate net asset value of their common shares held immediately prior to the merger(s). Approval of the merger of GPM into GOF is not contingent upon approval of GGM into GOF, and likewise, approval of the merger of GGM into GOF is not contingent upon approval of GPM into GOF.

More information regarding the proposed mergers is provided in the Combined Proxy Statement/Prospectus that was filed on June 29, 2021 with the Securities and Exchange Commission ("SEC") and available on the SEC's website (www.sec.gov). Investors and security holders of GPM, GGM and GOF are urged to read the Combined Proxy Statement/Prospectus and other documents filed with the SEC carefully and in their entirety.

There is no guarantee of any future distribution or that the current returns and distribution rate will be maintained.

Please see the Distributions to Shareholders & Annualized Distribution Rate on page 24, and Note 2(f) on page 53 for more information on distributions for the period.

For the year ended May 31, 2021, 68.7% of the distributions were characterized as ordinary income and 31.3% of the distributions were characterized as return of capital. The final determination of the tax character of the distributions paid by the Fund in 2021 will be reported to shareholders in January 2022.

⁸ l ^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT}

What influenced the Fund’s performance?

Since the second quarter of 2020, the high yield market has remained on an upward trajectory amid COVID-19 vaccine progress and optimism around fiscal stimulus. Credit cycles move through a series of phases: recession, repair, recovery, expansion, and a speculative phase. Each phase can take several months or even years to unfold, but the unprecedented and ongoing policy response to the COVID-19 shock has accelerated the progression from one phase to the next. Risk asset prices troughed in the recession and bounced back faster than ever before with corporations repairing their balance sheets. Although these features make it more difficult to pinpoint our current position in the credit cycle, our research suggests that we are in the recovery phase, in which we expect to see strong earnings growth, low default volumes, upward rating migration, and tighter spreads.

High-yield credit spreads have only been tighter 8% of the time dating back over 20 years. It is unusual for spreads to be this tight during the recovery phase of the credit cycle, as they typically get to their tightest during later phases. This bodes for even tighter spreads as we get into later phases of this cycle. However, the level of credit spreads must be measured and assessed relative to forward-looking default expectations. Our view is that fundamental conditions support staying long credit despite historically tight credit spreads, just as they did in the early 1990s when spreads stayed near similar levels for years.

The Fund experienced strong performance over the period with returns more than double the high yield market with contributions from across sectors. The Fund increased its exposure to the Consumer Cyclical sector which was deeply impacted by COVID-19 and was among the top performers as the economy reopened. The Fund was active in the primary market as new issuance was robust and the new issues performed well. The allocation to bank loans significantly outperformed the broader market and an overweight to CCC rated credit, which was the top performing rating category, was accretive. Leverage in the Fund and the small allocation to equities issued in connection with a reorganization or restructuring of a borrower also added to performance.

How is the Fund positioned for the coming months?

With the economy improving and monetary policy anchoring Treasury rates at low levels, we remain constructive on below investment-grade opportunities in bonds and loans. Credit spreads have room to tighten given the lack of yield across fixed income, and the Fund currently has an annualized distribution yield of 10.23% based on its ending market price of $21.27 at May 31, 2021. Default expectations continue to decrease, and rating migration continues to improve coupled with recovering corporate fundamentals. We have identified opportunities in cable, food and beverage, and technology companies that have successfully navigated the impact of COVID-19 and should perform well going forward.

The Fund is well-positioned across its three primary asset class exposures, with the largest allocation to high yield bonds, followed by bank loans and a small allocation to investment grade corporates. The mix between bonds and loans varies according to the relative valuation of the two asset classes and

^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT} l ⁹

availability of attractively priced assets. Among the high yield allocation, the Fund’s exposure to B-rated credits is its largest, and the Fund has incrementally added to BB-rated exposure while moderately reducing the CCC-rated exposure.

The Fund invests in non-U.S. dollar-denominated assets when the risk-return profile is favorable. Non-U.S. dollar-denominated assets comprise less than 1% of the Fund. The Fund uses forward foreign currency exchange contracts to hedge exchange rate risk, which minimizes the effects of currency fluctuations.

Any other comments about the Fund?

The Fund continues to avoid companies with heavy capital expenditure needs that can impair cash flow generation. Companies with recurring revenue streams, strong cash flows, and high-quality margins remain the focus. Overall, we remain concentrated on credit selection, which we believe will become increasingly important to returns in the event of market volatility.

What is the Fund’s duration?

The portfolio has consistently maintained a defensive stance to interest rate volatility with an underweight to duration. The effective duration for the Fund as of May 31, 2021, was 3.4 years which is slightly below the broader high yield market. A sizable allocation to bank loans, whose coupons generally reset quarterly, provides some protection against changes in interest rates.

Discuss the impact of leverage for the period.

The Fund utilizes leverage as part of its investment strategy, to finance the purchase of additional securities that provide increased income and potentially greater appreciation to common shareholders than could be achieved from a portfolio that is not leveraged. As opportunities arise, leverage may increase to add income as borrowing costs remain low.

With the low cost of borrowing, the amount of leverage used by the Fund is accretive to income generation. As of May 31, 2021, the Fund’s leverage was approximately 31% of managed assets (including the proceeds of leverage), compared with about 23% at the beginning of the period. While leverage increases the income of the Fund in yield terms, it also amplifies the effects of changing market prices in the portfolio and can cause the Fund’s NAV to change to a greater degree than the overall market. This can create volatility in Fund pricing but should not affect the Fund’s ability to pay dividends under normal circumstances.

Risks and Other Considerations

The global ongoing crisis caused by the outbreak of COVID-19 is causing materially reduced consumer demand and economic output, disrupting supply chains, resulting in market closures, travel restrictions and quarantines, and adversely impacting local and global economies. Investors should be aware that in light of the current uncertainty, volatility and distress in economies, financial markets, and labor and public health conditions all over the world, the Fund’s investments and a shareholder’s investment in the Fund are subject to sudden and substantial losses, increased volatility and other adverse events. Firms through which investors invest with the Fund, the Fund, its service providers, the markets in which it invests and market intermediaries are also impacted by quarantines and similar measures intended to contain the ongoing pandemic, which can obstruct their functioning and subject them to heightened operational risks.

The views expressed in this report reflect those of the portfolio managers only through the report period as stated on the cover. These views are subject to change at any time, based on market and other conditions and should not be construed as a recommendation of any kind. The material may also include forward looking statements that involve risk and uncertainty, and there is no guarantee that any predictions will come to pass.

There can be no assurance that the Fund will achieve its investment objectives. The value of the Fund will fluctuate with the value of the underlying securities. Risk is inherent in all investing, including the loss of your entire principal. Therefore, before investing you should consider the risks carefully.

The Fund is subject to various risk factors. Certain of these risk factors are described below. Please see the Fund’s Prospectus, Statement of Additional Information (SAI) and guggenheiminvestments.com/ggm for a more detailed description of the risks of investing in the Fund. Shareholders may access the Fund’s Prospectus and SAI on the EDGAR Database on the Securities and Exchange Commission’s website at www.sec.gov.

The fact that a particular risk below is not specifically identified as being heightened under current conditions does not mean that the risk is not greater than under normal conditions.

Below Investment Grade Securities Risk. High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, and present more credit risk than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions. This exposure may be obtained through investments in other investment companies. Generally, the risks associated with high yield securities are heightened during times of weakening economic conditions or rising interest rates and are therefore especially heightened under current conditions.

¹² l ^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT}

Corporate Bond Risk. Corporate bonds are debt obligations issued by corporations and other business entities. Corporate bonds may be either secured or unsecured. Collateral used for secured debt includes real property, machinery, equipment, accounts receivable, stocks, bonds or notes. If a bond is unsecured, it is known as a debenture. Bondholders, as creditors, have a prior legal claim over common and preferred stockholders as to both income and assets of the corporation for the principal and interest due them and may have a prior claim over other creditors if liens or mortgages are involved. Interest on corporate bonds may be fixed or floating, or the bonds may be zero coupons. Interest on corporate bonds is typically paid semi-annually and is fully taxable to the bondholder. Corporate bonds contain elements of both interest-rate risk and credit risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. Corporate bonds usually yield more than government or agency bonds due to the presence of credit risk. Depending on the nature of the seniority provisions, a senior corporate bond may be junior to other credit securities of the issuer. The market value of a corporate bond may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments.

Credit Risk. The Fund could lose money if the issuer or guarantor of a debt instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. Also, the issuer, guarantor or counterparty may suffer adverse changes in its financial condition or be adversely affected by economic, political or social conditions that could lower the credit quality (or the market’s perception of the credit quality) of the issuer or instrument, leading to greater volatility in the price of the instrument and in shares of the Trust. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit quality rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for the Trust to sell at an advantageous price or time. The risk of the occurrence of these types of events is especially heightened under current conditions.

Current Fixed-Income and Debt Market Conditions. Fixed-income and debt market conditions are highly unpredictable and some parts of the market are subject to dislocations. In response to the crisis initially caused by the outbreak of COVID-19, as with other serious economic disruptions, governmental authorities and regulators have enacted and are enacting significant fiscal and monetary policy changes, including providing direct capital infusions into companies, creating new monetary programs and

^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT} l ¹³

lowering interest rates considerably. These actions present heightened risks to fixed-income and debt instruments, and such risks could be even further heightened if these actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes. In light of these actions and current conditions, interest rates and bond yields in the United States and many other countries are at or near historic lows, and in some cases, such rates and yields are negative. The current very low or negative interest rates are magnifying the Fund’s susceptibility to interest rate risk and diminishing yield and performance. In addition, the current environment is exposing fixed-income and debt markets to significant volatility and reduced liquidity for Fund investments.

Derivatives Transactions Risk. The Fund may utilize derivatives, including futures contracts and other strategic transactions, to seek to earn income, facilitate portfolio management and mitigate risks. Participation in derivatives markets transactions involves investment risks and transaction costs to which the Fund would not be subject absent the use of these strategies (other than its covered call writing strategy and put option writing strategy). If the Sub-Adviser (Guggenheim Partners Investment Management, LLC or GPIM) is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited.

Interest Rate Risk. Fixed-income and other debt instruments are subject to the possibility that interest rates could change (or are expected to change). Changes in interest rates, including changes in reference rates used in fixed-income and other debt instruments (such as the London Interbank Offered Rate (“LIBOR”)) may adversely affect the Fund’s investments in these instruments, such as the value or liquidity of, and income generated by, the investments. In addition, changes in interest rates, including rates that fall below zero, can have unpredictable effects on markets and can adversely affect the Fund’s yield, income and performance. Generally, when interest rates increase, the values of fixed-income and other debt instruments decline, and when interest rates decrease, the values of fixed-income and other debt instruments rise. In response to the crisis initially caused by the outbreak of COVID-19, as with other serious economic disruptions, governmental authorities and regulators are enacting significant fiscal and monetary policy changes, including providing direct capital infusions into companies, creating new monetary programs and lowering interest rates considerably. These actions present heightened risks to fixed-income and debt instruments, and such risks could be even further heightened if these actions are unexpectedly or suddenly reversed or are ineffective in achieving their desired outcomes. In light of these actions and current conditions, interest rates and bond yields in the United States and many other countries are at or near historic lows, and in some cases, such rates and yields are negative. The current very low or negative interest rates are magnifying the Fund’s susceptibility to interest rate risk and diminishing yield and performance.

Investment in Loans Risk. The Fund may purchase loans on a direct assignment basis from a participant in the original syndicate of lenders or from subsequent assignees of such interests. Loans may offer a fixed or floating interest rate. Loans are often below investment grade and may be unrated. The Fund’s investments in loans can also be difficult to value accurately and may be more susceptible to liquidity risk than fixed-income instruments of similar credit quality and/or maturity. Participations in loans may

¹⁴ l ^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT}

subject the Fund to the credit risk of both the borrower and the seller of the participation and may make enforcement of loan covenants, if any, more difficult for the Fund as legal action may have to go through the seller of the participation (or an agent acting on its behalf). Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower’s operations or assets and by providing certain information and consent rights to lenders. The Fund invests in or is exposed to loans and other similar debt obligations that are sometimes referred to as “covenant-lite” loans or obligations, which are generally subject to more risk than investments that contain traditional financial maintenance covenants and financial reporting requirements. The terms of many loans and other instruments are tied to the London Interbank Offered Rate (“LIBOR”), which functions as a reference rate or benchmark. It is anticipated that LIBOR will ultimately be discontinued, which may cause increased volatility and illiquidity in the markets for instruments with terms tied to LIBOR or other adverse consequences, such as decreased yields and reduction in value, for these instruments. These events may adversely affect the Fund and its investments in such instruments.

Senior Loans Risk. The Fund may invest in senior secured floating rate loans made to corporations and other non-governmental entities and issuers (“Senior Loans”). Senior Loans typically hold the most senior position in the capital structure of the issuing entity, are typically secured with specific collateral and typically have a claim on the assets and/or stock of the borrower that is senior to that held by subordinated debt holders and stockholders of the borrower. The Fund’s investments in Senior Loans are generally rated below investment grade or unrated but believed by the Adviser to be of below investment grade quality and are considered speculative because of the credit risk of their issuers. The risks associated with such Senior Loans are similar to the risks of other lower grade securities, although Senior Loans are typically senior in payment priority and secured on a senior priority basis in contrast to subordinated and unsecured securities. Senior Loans’ higher priority has historically resulted in generally higher recoveries in the event of a corporate reorganization. In addition, because their interest payments are adjusted for changes in short-term interest rates, investments in Senior Loans have less interest rate risk than certain other lower grade securities, which may have fixed interest rates.

Second Lien Loans Risk. The Fund may invest in “second lien” secured floating rate loans made to public and private corporations and other non-governmental entities and issuers for a variety of purposes (“Second Lien Loans”). Second Lien Loans are subject to the same risks associated with investment in Senior Loans and other lower grade debt securities. However, Second Lien Loans are second in right of payment to Senior Loans and therefore are subject to the additional risk that the cash flow of the borrower and any property securing the Loan may be insufficient to meet scheduled payments and repayment of principal after giving effect to the senior secured obligations of the borrower. Second Lien Loans are expected to have greater price volatility and exposure to losses upon default than Senior Loans and may be less liquid.

Subordinated Secured Loans Risk. Subordinated secured loans generally are subject to similar risks as those associated with investment in Senior Loans, Second Lien Loans and below investment grade securities. However, such loans may rank lower in right of payment than any outstanding Senior Loans, Second Lien Loans or other debt instruments with higher priority of the borrower and therefore are subject to additional risk that the cash flow of the borrower and any property securing the loan may be insufficient to meet scheduled payments and repayment of principal in the event of default or bankruptcy after giving effect to the higher ranking secured obligations of the borrower. Subordinated secured loans are expected to have greater price volatility than Senior Loans and Second Lien Loans and may be less liquid.

Unsecured Loans Risk. Unsecured loans generally are subject to similar risks as those associated with investment in Senior Loans, Second Lien Loans, subordinated secured loans and below investment grade securities. However, because unsecured loans have lower priority in right of payment to any higher ranking obligations of the borrower and are not backed by a security interest in any specific collateral, they are subject to additional risk that the cash flow of the borrower and available assets may be insufficient to meet scheduled payments and repayment of principal after giving effect to any higher ranking obligations of the borrower. Unsecured loans are expected to have greater price volatility than Senior Loans, Second Lien Loans and subordinated secured loans and may be less liquid.

Leverage Risk. The Fund’s use of leverage, through borrowings or instruments such as derivatives, causes the Fund to be more volatile and riskier than if it had not been leveraged. Although the use of leverage by the Fund may create an opportunity for increased return, it also results in additional risks and can magnify the effect of any losses. The effect of leverage in a declining market is likely to cause a greater decline in the net asset value of the Fund than if the Fund were not leveraged, which may result in a greater decline in the market price of the Fund shares. There can be no assurance that a leveraging strategy will be implemented or that it will be successful during any period during which it is employed. Recent economic and market events have contributed to severe market volatility and caused severe liquidity strains in the credit markets. If dislocations in the credit markets continue, the Fund’s leverage costs may increase and there is a risk that the Fund may not be able to renew or replace existing leverage on favorable terms or at all. If the cost of leverage is no longer favorable, or if the Fund is otherwise required to reduce its leverage, the Fund may not be able to maintain distributions at historical levels and common shareholders will bear any costs associated with selling portfolio securities. The Fund’s total leverage may vary significantly over time. To the extent the Fund increases its amount of leverage outstanding, it will be more exposed to these risks.

Management Risk. The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, causing the Fund to fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies.

Market Risk. The value of, or income generated by, the investments held by the Fund are subject to the possibility of rapid and unpredictable fluctuation. The value of certain investments (e.g., equity securities) tends to fluctuate more dramatically over the shorter term than do the value of other asset classes. These movements may result from factors affecting individual companies, or from broader influences, including real or perceived changes in prevailing interest rates, changes in inflation or expectations about inflation, investor confidence or economic, political, social or financial market conditions, natural/environmental disasters, cyber attacks, terrorism, governmental or quasi-governmental actions, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and other similar events, each of which may be temporary or last for extended periods. For example, the crisis initially caused by the outbreak of COVID-19 is causing materially reduced consumer demand and economic output, disrupting supply chains, resulting in market closures, travel restrictions and quarantines, and adversely impacting local and global economies. As with other serious economic disruptions, governmental authorities and regulators are responding to this crisis with significant fiscal and monetary policy changes, which could further increase volatility in securities and other financial markets, reduce market liquidity, heighten investor uncertainty and adversely affect the value of the Fund’s investments and the performance of the Fund. Administrative changes, policy reform and/or changes in law or governmental regulations can result in expropriation or nationalization of the investments of a company in which the Fund invests.

Options Risk. The ability of the Fund to achieve its investment objective is partially dependent on the successful implementation of its covered call and put option strategies. The Fund may purchase and write call options on individual securities, securities indices, exchange-traded funds (“ETFs”) and baskets of securities. The buyer of an option acquires the right, but not the obligation, to buy (a call option) or sell (a put option) a certain quantity of a security (the underlying security) or instrument, at a certain price up to a specified point in time or on expiration, depending on the terms. The seller or writer of an option is obligated to sell (a call option) or buy (a put option) the underlying instrument. A call option is “covered” if the Fund owns the security underlying the call or has an absolute right to acquire the security without additional cash consideration (or, if additional cash consideration is required, cash or cash equivalents in such amount are segregated by the Fund’s custodian). As a seller of covered call options, the Fund faces the risk that it will forgo the opportunity to profit from increases in the market value of the security covering the call option during an option’s life. As the Fund writes covered calls over more of its portfolio, its ability to benefit from capital appreciation becomes more limited. A call option is “uncovered” if the Fund does not own the instrument underlying the call and does not have an absolute right to acquire the security without additional cash consideration. A put option is “covered” if the fund segregates cash or cash equivalents in an amount equal to the exercise price with the Fund’s custodian. As a seller of covered put options, the Fund bears the risk of loss if the value of the underlying instrument declines below the exercise price minus the put premium.

Prepayment Risk. Certain debt instruments, including loans and mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur more quickly or earlier than expected. In this event, the Fund might be forced to forego future interest income on the principal

^GGM l ^{GUGGENHEIM CREDIT ALLOCATION FUND ANNUAL REPORT} l ¹⁷

repaid early and to reinvest income or proceeds at generally lower interest rates, thus reducing the Fund’s yield. These types of instruments are particularly subject to prepayment risk, and offer less potential for gains, during periods of declining interest rates.

Structured Finance Investments Risk. The Fund’s structured finance investments may consist of residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”) issued by governmental entities and private issuers, asset-backed securities (“ABS”), structured notes, credit-linked notes and other types of structured finance securities. Holders of structured finance investments bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. The Fund may invest in structured finance products collateralized by low grade or defaulted loans or securities. Investments in such structured finance products are subject to the risks associated with below investment grade securities. Such securities are characterized by high risk. It is likely that an economic recession could severely disrupt the market for such securities and may have an adverse impact on the value of such securities. Structured finance securities are typically privately offered and sold, and thus are not registered under the securities laws. As a result, investments in structured finance securities may be characterized by the Fund as illiquid securities; however, an active dealer market may exist which would allow such securities to be considered liquid in some circumstances.

Mortgage-Backed Securities (“MBS”) Risk. MBS represent an interest in a pool of mortgages. The risks associated with MBS include: (1) credit risk associated with the performance of the underlying mortgage properties and of the borrowers owning these properties; (2) risks associated with their structure and execution (including the collateral, the process by which principal and interest payments are allocated and distributed to investors and how credit losses affect the return to investors in such MBS); (3) risks associated with the servicer of the underlying mortgages; (4) adverse changes in economic conditions and circumstances, which are more likely to have an adverse impact on MBS secured by loans on certain types of commercial properties than on those secured by loans on residential properties; (5) prepayment risk, which can lead to significant fluctuations in the value of the MBS; (6) loss of all or part of the premium, if any, paid; and (7) decline in the market value of the security, whether resulting from changes in interest rates, prepayments on the underlying mortgage collateral or perceptions of the credit risk associated with the underlying mortgage collateral.

Commercial Mortgage-Backed Securities Risk. CMBS are subject to particular risks, including lack of standardized terms, shorter maturities than residential mortgage loans and providing for payment of all or substantially all of the principal only at maturity rather than regular amortization of principal. In addition, commercial lending generally is viewed as exposing the lender to a greater risk of loss than residential lending. Economic downturns and other events that limit the activities of and demand for commercial retail and office spaces (such as the current crisis) adversely impact the value of such securities.

Residential Mortgage-Backed Securities Risk. Credit-related risk on RMBS arises from losses due to delinquencies and defaults by the borrowers in payments on the underlying mortgage loans and breaches by originators and servicers of their obligations under the underlying documentation pursuant to which the RMBS are issued. The rate of delinquencies and defaults on residential mortgage loans and the aggregate amount of the resulting losses will be affected by a number of factors, including general economic conditions, particularly those in the area where the related mortgaged property is located, the level of the borrower’s equity in the mortgaged property and the individual financial circumstances of the borrower. These risks are elevated given the current distressed economic, market, public health and labor conditions, notably, increased levels of unemployment, delays and delinquencies in payments of mortgage and rent obligations, and uncertainty regarding the effects and extent of government intervention with respect to mortgage payments and other economic matters.

Asset-Backed Securities Risk. While traditional fixed-income securities typically pay a fixed rate of interest until maturity, when the entire principal amount is due, an ABS represents an interest in a pool of assets, such as automobile loans, credit card receivables, unsecured consumer loans or student loans, that has been securitized and provides for monthly payments of interest, at a fixed or floating rate, and principal from the cash flow of these assets. This pool of assets (and any related assets of the issuing entity) is the only source of payment for the ABS. The ability of an ABS issuer to make payments on the ABS, and the timing of such payments, is therefore dependent on collections on these underlying assets. The recoveries on the underlying collateral may not, in some cases, be sufficient to support payments on these securities, which may result in losses to investors in an ABS. These risks are elevated given the currently distressed economic, market, labor and public health conditions.

CLO, CDO and CBO Risk. In addition to the general risks associated with credit securities discussed herein, collateralized loan obligations (“CLOs”), collateralized debt obligations (“CDOs”), and collateralized bond obligations (“CBOs”) are subject to additional risks. CLOs, CDOs and CBOs are subject to risks associated with the possibility that distributions from collateral securities may not be adequate to make interest or other payments.

Valuation Risk. The Fund may invest without limitation in unregistered securities, restricted securities and securities for which there is no readily available trading market. It may be difficult for the Fund to purchase and sell a particular investment at the price at which it has been valued by the Fund for purposes of the Fund’s net asset value, causing the Fund to be unable to realize what the Fund believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. Based on its investment strategies, a significant portion of the Fund’s investments can be difficult to value and thus particularly prone to the foregoing risks.

In addition to the foregoing risks, investors should note that the Fund reserves the right to merge or reorganize with another fund, liquidate or convert into an open-end fund, in each case subject to applicable approvals by shareholders and the Fund’s Board of Trustees as required by law and the Fund’s governing documents.
