S&P 1500

The S&P 1500, or S&P Composite 1500 Index, is a stock market index of US stocks published by S&P Global. It combines stocks in the S&P 500, S&P MidCap 400, and S&P SmallCap 600.^[2] This index covers approximately 90% of the market capitalization of U.S. stocks and is a broad measure of the U.S. equity market.

The index was launched on May 18, 1995 with a first value date of December 30, 1994.

Standard & Poor's also provides the S&P 900 index (a combination of the S&P 500 index plus the S&P MidCap 400)^[3] and the S&P 1000 (the S&P MidCap 400 plus the S&P SmallCap 600 index).^[4]

Like many indexes, the headline quote for the "S&P 1500" is a price return index; however, there is also "total return" version of the index, which includes dividends, interest and distributions (when applicable). These versions differ in how dividends are accounted for. The price return version does not account for dividends; it only captures the changes in the prices of the index components.^[5]
