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 with respect to Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in Hartford Funds. For purchases of Class T shares, you may qualify for a sales charge discount if you purchase $250,000 or more in a single transaction. 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 90 of the Fund’s statutory prospectus and the “Purchase and Redemption of Shares” section beginning on page 162 of the Fund’s statement of additional information. In addition, descriptions of any financial intermediary specific sales load waivers and/or discounts are reproduced in Appendix A to the statutory prospectus based on information provided by the financial intermediaries. The table and examples below do not reflect any transaction fees that may be charged by financial intermediaries. In addition, the table and examples below do not reflect any commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or 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)

“Total other expenses” for all classes, except Class T, have been restated to reflect current transfer agency fees. "Total other expenses" for Class T shares are based on estimated amounts.

​

(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 "Total other expenses."

​

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

​

•

You reinvest all dividends and distributions

​

•

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 123% 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.

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 may decline in value due to the activities and financial prospects of individual companies or 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.

Investment Strategy 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. There is no guarantee that the Fund’s investment objective will be achieved.

Asset Allocation Risk − The risk that if the Fund’s strategy for allocating assets among different asset classes and/or 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, 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 seek to earn additional income by engaging 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.

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.
