By far the most popular index used is the Standard & Poor’s 500-Stock Index, an index that well represents the major corporations in the U.S. market. But now, although I still recommend indexing, or so-called passive investing, there are valid criticisms of too narrow a definition of indexing. Many people incorrectly equate indexing with a strategy of simply buying the S&P 500 Index. That is no longer the only game in town.
