This fund invests in stocks of large U.S. companies in market sectors that tend to grow more quickly than the broad market. This low-cost index fund follows a buy-and-hold approach and invests in substantially all of the stocks represented in its broad benchmark. The fund’s primary risk, apart from general stock market volatility, comes from the fact that its focus on large-capitalization growth stocks may, at times, underperform the broader stock market.With respect to 75% of its total assets, the fund may not: (1) purchase more than 10% of the outstanding voting securities of any one issuer or (2) purchase securities of any issuer if, as a result, more than 5% of the fund’s total assets would be invested in that issuer’s securities; except as may be necessary to approximate the composition of its target index. This limitation does not apply to obligations of the U.S. government or its agencies or instrumentalities.Read More
