The fund seeks long-term capital appreciation and growth of income with current income a secondary objective.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below.

Fees and Expenses of the Fund

	Investor Class		I Class
Shareholder fees (fees paid directly from your investment)
Maximum account fee	$20	a	-

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

Management fees	0.73	%	0.58	%
Other expenses	-		-
Acquired fund fees and expenses	0.04		0.04
Total annual fund operating expenses	0.77	b	0.62	b
Fee waiver/expense reimbursement	(0.04)		(0.04)
Total annual fund operating expenses after fee waiver/expense reimbursement	0.73	b	0.58	b

a	Subject to certain exceptions and account minimums, accounts are charged an annual $20 fee.
b	The figures shown in the fee table do not match the "Ratios to average net assets" shown in the Financial Highlights table, as those figures do not include acquired fund fees and expenses.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Investor Class	$	75	$	233	$	406	$	906
I Class		59		186		324		726

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 the fund's shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 26.4% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities. Any derivatives that provide exposure to the investment focus suggested by the fund's name, or to one or more market risk factors associated with the investment focus suggested by the fund's name, are counted (as applicable) toward compliance with the fund's 80% investment policy.

The fund seeks to achieve its objective by primarily investing in a mix of other T. Rowe Price equity funds (underlying funds) that focus on various areas of the overall stock markets. The fund broadly diversifies its assets among underlying funds representing specific market segments by normally investing in a variety of U.S. equity funds and, from time to time, a money market fund. In addition, the fund may invest in individual securities on a limited basis. The goal is to maintain broad exposure to several markets in an attempt to reduce the impact of markets that are declining and to benefit from strong performance in particular market segments over time.

The various underlying funds and any individual securities focus on the U.S. stock market. The fund's focus on U.S. stocks is represented by a diversified mix of underlying funds that employ growth and value investment approaches and consist of small-cap, mid-cap, and large-cap stocks.

The adviser decides how much of the fund's assets to allocate to particular underlying funds and asset classes based on the outlook for, and on the relative valuations of, the underlying funds and the various markets and asset classes in which they invest. The adviser weights such factors as the outlook for inflation and the global economy; corporate earnings; relative values and prospects for growth and value stocks, dividend-paying stocks, market capitalizations, and certain industries; and the overall outlook for U.S. stocks.

The adviser periodically reviews the mix of underlying funds and the percentages allocated to them. The fund may sell shares of the underlying funds for a variety of reasons, including to realize gains, limit losses, or redeploy assets into more promising opportunities.

Principal Risks

As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund's share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater in unfavorable or uncertain market conditions, are summarized as follows:

Active management/Asset allocation: The fund's overall level of risk will directly correspond to the risks of the underlying funds in which it invests. By investing in many underlying funds, the fund has partial exposure to the risks of different areas of the market. However, the selection of the underlying funds and the allocation of the fund's assets among the various asset classes, market sectors, and investment styles represented by those underlying funds could cause the fund to underperform other funds with a similar benchmark or investment objective(s).

Investments in other funds: The fund bears the risk that its underlying funds will fail to successfully employ their investment strategies. One or more underlying fund's underperformance or failure to meet its investment objective(s) as intended could cause the fund to underperform similarly managed funds.

SUMMARY

3

Market conditions: The value of the fund's investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by an underlying fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of an underlying fund's holdings and markets generally, including geopolitical developments (such as trade and tariff arrangements, sanctions, and cybersecurity attacks), recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses. Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

Equity exposure: An underlying equity fund's share price can fall because of weakness in the overall stock markets, a particular industry, or specific holdings. Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of an underlying equity fund may decline due to general weakness or volatility in the stock markets, adverse conditions impacting a particular industry or market sector, or factors affecting an investment style or market capitalization targeted by the fund.

Market capitalization: Because the fund invests in certain underlying funds that focus on a particular market capitalization, its share price may be negatively affected if investing in that market capitalization falls out of favor. Small- and mid-cap companies often have less experienced management, more limited financial resources, and less publicly available information than large-cap companies, and tend to be more sensitive to changes in overall economic conditions. As a result, investments in small-cap and mid-cap companies are likely to be more volatile than investments in large-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and they may be less capable of responding quickly to competitive challenges and industry changes.

Investment style: Because the fund invests in certain underlying funds that focus on growth stocks and certain underlying funds that focus on value stocks, its share price may be negatively affected if either investing approach falls out of favor. Growth stocks tend to be more volatile than the overall stock market and are more sensitive to changes in current or expected earnings. Value stocks carry the risk that investors will not recognize their intrinsic value for a long time (or at all) or that they are actually appropriately priced at a low level.

Dividend-paying stocks: To the extent the fund invests in an underlying fund that focuses on dividend-paying stocks, it is exposed to greater volatility and the risk of stock market declines that could cause the fund to underperform funds with similar objectives. Stocks of established companies paying high dividends may not participate in a broad market advance to the same degree as most other stocks, and a sharp rise in interest rates could cause a company to reduce or eliminate its dividend.

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund's assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund's service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality.

Performance

The following performance information provides some indication of the risks of investing in the fund. The fund's performance information represents only past performance (before and after taxes) and is not necessarily an indication of future results.

The following bar chart illustrates how much returns can differ from year to year by showing calendar year returns and the best and worst calendar quarter returns during those years for the fund's Investor Class. Returns for other share classes vary since they have different expenses.

		Quarter Ended	Total Return			Quarter Ended	Total Return
	Best Quarter	6/30/20	20.92%		Worst Quarter	3/31/20	-21.60%

The following table shows the average annual total returns for each class of the fund that has been in operation for at least one full calendar year. The fund's performance information included in the table is compared with a regulatory required index that represents an overall securities market (Russell 3000^® Index). In addition, the table may also include one or more indexes that align to the fund's investment strategy.

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other share classes.

Purchase and Sale of Fund Shares

The Investor Class generally requires a $2,500 minimum initial investment ($1,000 minimum initial investment if opening an IRA, a custodial account for a minor, or a small business retirement plan account). Additional purchases generally require a $100 minimum. These investment minimums generally are waived for financial intermediaries and certain employer-sponsored retirement plans submitting orders on behalf of their customers.

The I Class requires a $500,000 minimum initial investment per fund per account registration, although the initial investment minimum generally is waived or reduced for financial intermediaries, eligible retirement plans, certain accounts for which T. Rowe Price or its affiliates have discretionary investment authority, qualifying directly held accounts, and certain other accounts.

For investors holding shares of the fund directly with T. Rowe Price, you may purchase, redeem, or exchange fund shares by mail; by telephone (1-800-225-5132 for IRAs and nonretirement accounts; 1-800-492-7670 for small business retirement plans; and 1-800-638-8790 for institutional investors and financial intermediaries); or, for certain other accounts, by accessing your account online through troweprice.com.

If you hold shares through a financial intermediary or retirement plan, you must purchase, redeem, and exchange shares of the fund through your intermediary or retirement plan. You should check with your intermediary or retirement plan to determine the investment minimums that apply to your account.

Tax Information

Any dividends or capital gains are declared and paid annually, usually in December. Redemptions or exchanges of fund shares and distributions by the fund, whether or not you reinvest these amounts in additional fund shares, generally may be taxed as ordinary income or capital gains unless you invest through a tax-deferred account (in which case you will be taxed upon withdrawal from such account).

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), 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 salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
