FRED and its associated services will include 10 years of daily history for Standard & Poors and Dow Jones Averages series.  The S&P 500 is regarded as a gauge of the large cap U.S. equities market. The index includes 500 leading companies in leading industries of the U.S. economy, which are publicly held on either the NYSE or NASDAQ, and covers 75% of U.S. equities. Since this is a price index and not a total return index, the S&P 500 index here does not contain dividends.  Copyright © 2016, S&P Dow Jones Indices LLC. All rights reserved.
