Connect with Vanguard ® > vanguard.comPlain talk about riskAn investment in the fund could lose money over short or even long periods. You should expect the fund’s share price and total return to fluctuate within awide range, like the fluctuations of the overall stock market. The fund’s performance could be hurt by: Stock market risk: The chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising stock prices and periods offalling stock prices. The fund’s target index may, at times, become focused in stocks of a particular sector, category, or group of companies. Because the fundseeks to track its target index, the fund may underperform the overall stock market.Investment style risk: The chance that returns from small-capitalization stocks will trail returns from the overall stock market. Historically, small-cap stockshave been more volatile in price than the large-cap stocks that dominate the overall market, and they often perform quite differently.
