There are a number of other S&P 500 index funds, including offerings from Fidelity and Schwab, which have nearly identical return figures. Those others, however, are hundredths of a percentage point lower in returns, and ever slightly higher in expense ratios. Vanguard also offers an ETF version of this, which is not listed here, with identical returns, expenses and asset levels.
