Investment Objective
The fund seeks to track the performance of a benchmark index that measures the investment return of small- and mid-capitalization U.S. stocks.
Strategy
The fund attempts to match the investment return of small- and mid-capitalization U.S. stocks by seeking to match the performance of its benchmark index, the Standard & Poors Completion Index (S&P Index). The S&P Index consists of primarily small- and mid-capitalization stocks and generally includes those U.S. stocks that are not included in the Standard & Poors 500 Stock Index.

Higher

Lower
Index investing provides investors with a convenient and relatively low-cost way to approximate the performance of a particular market. Because the fund is passively managed, its expenses are lower than the average actively managed fund. Assuming all other factors are equal, lower expenses can increase a fund's total return. Lower turnover should mean smaller capital gain distributions, which can raise a fund's after-tax returns.

Stocks can decline for many reasons, including adverse political or economic developments here or abroad, changes in investor psychology, or heavy institutional selling. The fund will be subject to the greater risks associated with small- and mid-cap stocks. Because the fund is designed to track the S&P Completion Index, it does not have the flexibility to shift assets toward stocks or sectors that are rising or away from stocks or sectors that are declining. As a result, actively managed funds may outperform this fund.
**This chart displays relative risk of each U.S. mutual fund listed using standard deviation of returns. Those values are provided in the bars at the top of the chart.

Methodology: We evaluate the standard deviation and its resulting placement within a specific risk/return category on an annual basis. A fund is generally placed in a risk/return category based on the 10-year standard deviation of its performance. If a fund is less than 10 years old, the actual fund performance history is supplemented with the primary prospectus benchmark history to obtain a full 10-year history, or longest time period available up to 10 years. For an Asset Allocation fund with less than 10 years of performance history, sub-strategy returns are used. When a sub-strategy is less than 10 years old, the actual sub-strategy performance history is supplemented with benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.

Risk return categories overlap; a fund with a standard deviation in the overlap between two categories, denoted by a plus (+), is placed so that its risk categorization is better aligned with anticipated return characteristics an investor may experience going forward at the discretion of T Rowe Price.

When a fund has a cash-like benchmark, denoted by a double plus (++), its standard deviation is estimated using only available fund returns. If the fund is less than 10 years old, benchmark returns are not used to obtain a full 10-year history because they would artificially suppress the volatility estimate.

All investments are subject to market risk, including the possible loss of principal. Standard deviation of returns, a measure of price volatility, is one measure of risk. Please consult the funds' prospectuses for a more complete discussion of the funds' risks.
