Dow Jones Wilshire 5000 Index

Wilshire 5000 Total Market Index

A capitalization-weighted index that tracks as many stocks being traded in the United States as possible. It tracks all stocks traded on the NYSE, American Stock Exchange, NASDAQ, and any other stock for which data is easily available. Thus, despite its name, it is usually tracking more than 5,000 stocks. It is the broadest index in the United States. The Wilshire 5000 is subdivided into four indices: one for large-cap, one for mid-cap, one for small-cap, and one for micro-cap stocks.

Dow Jones Wilshire 5000 Index. The Dow Jones Wilshire 5000 is a market capitalization weighted index of approximately 7,000 stocks.

It is the broadest US stock market index, tracking all the stocks traded on the New York Stock Exchange (NYSE), the American Stock Exchange (AMEX), the Nasdaq Stock Market (Nasdaq), and other US based stocks for which data is readily available.

The difference between the index's name (the 5000) and the number of stocks the index tracks at any one time occurs because the number of stocks being traded changes all the time.
