Vanguard 500 index investor
The investment seeks to track the performance of a benchmark index that measures the investment return of large-capitalization stocks. The fund employs a passive management investment approach designed to track the performance of the Standard & Poor's 500 index, a widely recognized benchmark of U.S. stock market performance that is dominated by the stocks of large U.S. companies. It invests all, or substantially all, of assets in the stocks that make up the index, holding each stock in approximately the same proportion as its weighting in the index.
