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 invest $10,000

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

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

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

Expense Example - THE HARTFORD HEALTHCARE FUND - USD ($)	Year 1	Year 3	Year 5	Year 10
Class A	676	942	1,229	2,042
Class C	309	646	1,108	2,390
Class I	104	325	563	1,248
Class R3	166	514	887	1,933
Class R4	135	421	729	1,601
Class R5	105	328	569	1,259
Class R6	94	293	509	1,131
Class Y	99	322	563	1,254
Class F	94	293	509	1,131

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

Expense Example No Redemption - THE HARTFORD HEALTHCARE FUND - USD ($)	Year 1	Year 3	Year 5	Year 10
Class A	676	942	1,229	2,042

Class R6	94	293	509	1,131
Class Y	99	322	563	1,254
Class F	94	293	509	1,131

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 fiscal year ended October 31, 2019, the Fund’s portfolio turnover rate was 35% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY.

Under normal circumstances, the Fund invests at least 80% of its assets in the equity securities of health care-related companies worldwide as selected by the sub-adviser, Wellington Management Company LLP (“Wellington Management”). Wellington Management's investment process focuses on stock selection through fundamental analysis. The Fund takes a broad approach to investing in the health care sector. It may invest in health-related companies, including companies in the pharmaceuticals, biotechnology, medical delivery, medical products, medical services, managed health care, health information services and emerging health-related subsectors. The Fund’s assets will be allocated across the major subsectors of the health care sector, with some representation typically maintained in each major subsector. The Fund will normally invest at least 25% of its total assets, in the aggregate, in the following industries: pharmaceuticals and biotechnology, medical products and health services. The Fund will invest in securities of issuers located in a number of different countries throughout the world, one of which may be the United States; however, the Fund has no limit on the amount of assets that may be invested in each country. The Fund may invest in securities of companies of any market capitalization.

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.

Healthcare Concentration Risk −The performance of a fund that focuses on a single industry or sector of the economy depends in large part on the performance of that industry or sector. The Fund’s focus on healthcare-related securities increases the Fund’s exposure to the risks associated with the healthcare-related sector, including changes in laws or regulations, lawsuits and regulatory proceedings, patent considerations, intense competition and rapid technological change and the potential for obsolescence. As a result, the Fund may be subject to increased price volatility and may be more susceptible to adverse developments than a fund that invests more widely.

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 and Small Cap Securities Risk −Investments in mid- and small-capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, including the risk of bankruptcy.

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.

Foreign Investments Risk −Investments in foreign securities may be riskier, more volatile, and less liquid 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. The impact of the United Kingdom’s 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.

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. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.
