4 Index Funds Beating the Market in August

When most people talk about passive investing with an index fund, the index those funds are generally tied to is the S&P 500. These stocks collectively represent between 80% and 85% of the U.S. equity market, and there's certainly no shortage of S&P 500-based mutual funds and exchange-traded funds to choose from.

It's certainly possible to be a passive index investor outside of Standard & Poor's popular market barometer, though. It's also possible some of these index funds will from time to time be able to outpace the broad market. Four names beating the S&P 500's August gain of 5.1% (so far) deserve a closer look.
