The Hartford Capital Appreciation Fund Summary Section

INVESTMENT OBJECTIVE.   The Fund seeks growth of capital.

Your Expenses.   The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts for Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in certain classes of Hartford mutual funds or 529 plans administered by Hartford Funds Management Company, LLC. More information about these and other discounts is available from your financial professional and in the “How Sales Charges Are Calculated” section beginning on page 93 of the Fund’s statutory prospectus and the “Purchase and Redemption of Shares” section beginning on page 153 of the Fund’s statement of additional information. Descriptions of any financial intermediary specific sales charge waivers and discounts are set forth in Appendix A to the statutory prospectus. In addition, the table and examples below do not reflect any transaction fees that may be charged by financial intermediaries or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class I, Class R6, Class Y, or Class F shares.

Shareholder Fees   (fees paid directly from your investment)

Annual Fund Operating Expenses   (expenses that you pay each year as a percentage of the value of your investment)

(1)

For investments over $1 million, a 1.00% maximum deferred sales charge may apply.

​

(2)

"Other expenses” for Class Y have been restated to reflect estimated amounts in connection with the new transfer agency fee effective May 1, 2019.

​

(3)

"Total annual fund operating expenses" do not correlate to the ratio of expenses to average net assets that is disclosed in the Fund’s annual report in the financial highlights table, which reflects the operating expenses of the Fund and does not include acquired fund fees and expenses. The ratio of expenses to average net assets that is disclosed in the Fund’s annual report in the financial highlights table for the applicable period also does not reflect the restated "Other expenses" for Class Y.

​

(4)

Hartford Administrative Services Company (“HASCO”), the Fund’s transfer agent, has contractually agreed to waive and/or reimburse a portion of the transfer agency fee to the extent necessary to maintain the transfer agency fee for Class Y as follows: 0.04%. This contractual arrangement will remain in effect until February 29, 2020 unless the Board of Directors of The Hartford Mutual Funds, Inc. approves its earlier termination.

​

Example.   The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

•

Your investment has a 5% return each year

​

•

The Fund’s operating expenses remain the same (except that the examples for Class Y reflect the expense limitation arrangement for only the first year)

​

•

You reinvest all dividends and distributions

​

3​

•

You pay any deferred sales charge due for the applicable period.

​

Your actual costs may be higher or lower. Based on these assumptions, for every $10,000 invested, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

You would pay the following expenses if you did not redeem your shares:

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 108% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.   The Fund normally invests at least 65% of its net assets in common stocks. The Fund may invest in securities of any market capitalization, but tends to focus on medium and large companies. The Fund may invest up to 25% of its net assets in securities of foreign issuers and non-dollar securities, including companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets.

The Fund seeks its investment objective by employing a multiple portfolio manager structure, which means the Fund has several components that are managed separately using different investment styles. Each component sleeve has a distinct investment philosophy and analytical process to identify specific securities for purchase or sale. Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, does not allocate a set percentage to any of these sleeves but instead seeks a flexible and diversified Fund profile. Together the investment strategies represent a wide range of investment philosophies, companies, industries and market capitalizations. Based on market or economic conditions, the Fund may, through its stock selection process, focus in one or more sectors of the market. The Fund may trade portfolio securities actively.

PRINCIPAL RISKS.   The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective. For more information regarding risks and investment matters, please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

4

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Mid-Cap Securities Risk − The securities of mid cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.

Active Investment Management Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. ​

Asset Allocation Risk − The risk that if the Fund’s strategy for allocating assets among different portfolio management teams does not work as intended, the Fund may not achieve its objective or may underperform other funds with similar investment strategies. The investment styles employed by the portfolio managers may not be complementary, which could adversely affect the performance of the Fund.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments. Certain European countries in which the Fund may invest have recently experienced significant volatility in financial markets and may continue to do so in the future. The impact of the United Kingdom’s intended departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

Emerging Markets Risk − The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk − The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.

Sector Risk − To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market.

Securities Lending Risk − The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

5​

Active Trading Risk − Active trading could increase the Fund's transaction costs and may increase your tax liability as compared to a fund with less active trading policies. These effects may adversely affect Fund performance.

Large Shareholder Transaction Risk − The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund's performance and liquidity. Similarly, large purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

Average Annual Total Returns.  The table below shows returns for the Fund over time compared to those of two broad-based market indices. After-tax returns, which are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes, are shown only for Class A shares and will vary for other classes. Actual after-tax returns, which depend on an investor’s particular tax situation, may differ from those shown and are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Class R6 shares commenced operations on November 7, 2014 and performance prior to that date is that of the Fund’s Class Y shares. Class F shares commenced operations on February 28, 2017 and performance prior to that date is that of the Fund’s Class I shares. To the extent a share class has adopted the prior performance of another share class that had different operating expenses, such performance has not been adjusted to reflect the different operating expenses. If the performance were adjusted, it may have been higher or lower. For more information regarding returns, see the “Performance Notes” section in the Fund’s statutory prospectus.

TAX INFORMATION.   The Fund’s distributions are generally taxable, and may be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Such tax-deferred arrangements may be taxed later upon withdrawal of monies from those arrangements.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES.   If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank or financial advisor), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary’s website for more information.

Investment Objective.   The Fund seeks growth of capital.

Your Expenses.   The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts for Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in certain classes of Hartford mutual funds or 529 plans administered by Hartford Funds Management Company, LLC.

More information about these and other discounts is available from your financial professional and in the “How Sales Charges Are Calculated” section beginning on page 93 of the Fund’s statutory prospectus and the “Purchase and Redemption of Shares” section beginning on page 153 of the Fund’s statement of additional information. Descriptions of any financial intermediary specific sales charge waivers and discounts are set forth in Appendix A to the statutory prospectus. In addition, the table and examples below do not reflect any transaction fees that may be charged by financial intermediaries or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class I, Class R6, Class Y, or Class F shares.

Shareholder Fees   (fees paid directly from your investment)

(1)

For investments over $1 million, a 1.00% maximum deferred sales charge may apply.

​

(2)

"Other expenses" for Class T are based on estimated amounts. "Other expenses" for Class Y have been restated to reflect estimated amounts in connection with the new transfer agency fee effective May 1, 2019.

​

(3)

Hartford Administrative Services Company (“HASCO”), the Fund’s transfer agent, has contractually agreed to waive and/or reimburse a portion of the transfer agency fee to the extent necessary to maintain the transfer agency fee for Class Y as follows: 0.06%. This contractual arrangement will remain in effect until February 29, 2020 unless the Board of Directors of The Hartford Mutual Funds, Inc. approves its earlier termination.

​

Example.   The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

You would pay the following expenses if you did not redeem your shares:

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategy.   Under normal circumstances, the Fund invests at least 80% of its assets in common stocks. The Fund invests in a diversified portfolio of common stocks of issuers located primarily in the United States. Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, chooses the Fund’s investments using fundamental research designed to identify issuers with improving quality metrics, business momentum and attractive relative valuations. The investment process is aided by a proprietary quantitative screening process that narrows the investment universe to companies that are consistent with the Fund’s investment strategy. The Fund’s portfolio seeks to be broadly diversified by industry and company. The Fund may invest in a broad range of market capitalizations, but tends to focus on large capitalization companies with market capitalizations similar to those of companies in the S&P 500 Index.

PRINCIPAL RISKS.   The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets.

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Active Investment Management Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. ​

Quantitative Investing Risk − The value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance. This may be as a result of the factors used in building the quantitative analytical framework, the weights placed on each factor, the accuracy of historical data supplied by third parties, and changing sources of market returns.

Securities Lending Risk − The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral.

Portfolio Turnover.  The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 31% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.   The Fund invests primarily in a portfolio of equity securities that typically have above average dividend yields and whose prospects for capital appreciation are considered favorable by the sub-adviser, Wellington Management Company LLP (“Wellington Management”). The Fund’s portfolio seeks to be broadly diversified by company and industry. Under normal market and economic conditions, at least 80% of the Fund’s net assets are invested in dividend paying equity securities. The Fund tends to focus on securities of larger, well-established companies with market capitalizations similar to those of companies in the S&P 500 Index. The Fund may invest up to 20% of its net assets in securities of foreign issuers and non-dollar securities.

Wellington Management uses fundamental analysis to evaluate a security for purchase or sale by the Fund. As a key component of its fundamental analysis, Wellington Management evaluates a company’s ability to sustain and potentially increase its dividend payments. Wellington Management also evaluates a company's business environment, management quality, balance sheet, income statement, anticipated earnings, revenues and dividends, and other related measures or indicators of value, including certain environmental, social and/or governance (ESG) factors.

PRINCIPAL RISKS.   The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment.

Market Risk − Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets.

Dividend Paying Security Investment Risk − Income provided by the Fund may be affected by changes in the dividend policies of the companies in which the Fund invests and the capital resources available for such payments at such companies. Issuers that have paid regular dividends or distributions to shareholders may not continue to do so at the same level or at all in the future. Dividend paying securities can fall out of favor with the market, causing the Fund during such periods to underperform funds that do not focus on dividends. The Fund’s focus on dividend paying investments may cause the Fund’s share price and total return to fluctuate more than those of funds that do not focus their investments on such investments.

Active Investment Management Risk − The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. ​

Equity Risk − The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Foreign Investments Risk − Investments in foreign securities may be riskier than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments. Certain European countries in which the Fund may invest have recently experienced significant volatility in financial markets and may continue to do so in the future. The impact of the United Kingdom’s intended departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

Currency Risk − The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.

Securities Lending Risk − The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Large Shareholder Transaction Risk − The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund's performance and liquidity. Similarly, large purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks, which are discussed in “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.

Average Annual Total Returns.  The table below shows returns for the Fund over time compared to those of two broad-based market indices. After-tax returns, which are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes, are shown only for Class A shares and will vary for other classes. Actual after-tax returns, which depend on an investor’s particular tax situation, may differ from those shown and are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Class R6 shares commenced operations on November 7, 2014 and performance prior to that date is that of the Fund’s Class Y shares. Class F shares commenced operations on February 28, 2017 and performance prior to that date is that of the Fund’s Class I shares. To the extent a share class has adopted the prior performance of another share class that had different operating expenses, such performance has not been adjusted to reflect the different operating expenses. If the performance were adjusted, it may have been higher or lower. For more information regarding returns, see the “Performance Notes” section in the Fund’s statutory prospectus.
