Where can you find historical stock market information?

Historical stock market information is available online from a variety of investor information websites and from the individual sites of publicly traded companies, reports Investopedia. The Securities and Exchange Commission also publishes the documents those companies are required to file, which include information vital to investors, according to the SEC.

The prevalent methods of predicting future stock prices analyze various aspects of the past performance of stocks, market indexes and the market as a whole. The methods vary widely, with no one method showing any significant degree of success over the others. Investors should therefore remember that past performance is an indicator rather than a predictor of future returns, advises Investopedia.
