Index funds are a type of mutual fund, which is a collection of many different stocks. Active funds profess to know which stocks will outperform the market. Index funds don't make that promise; stocks are weighted by their size relative to the rest of the market or use a weighting based on identifiable price or size characteristics. Because there's no magic formula or talent presumed in constructing these funds, they are cheap; if no one can beat the market, why pay 1 or 2 percent of your assets to someone who claims they can? If you believe in efficient markets you'd only hold index funds. This has been revolutionary for the average investor. Through the 1960s few Americans owned stock at all, and if they did they only held a handful of individual stocks, which was very risky. Now about 50 percent of the population owns stock, mostly through mutual funds and increasingly with allocations based on indexing. The average household can invest as well as many hedge funds, for a fraction of the price. The existence of index funds shows that the best innovations (in finance or any industry) are often the simplest.
