Information on daily closing stock market prices can be found on the websites of the Wall Street Journal, CNN Money and individual exchanges. The closing price is the price of a stock at the time the market closes, according to the U.S. Securities and Exchange Commission.
Individual reports of closing prices may vary based on the conventions of different sources, according to the SEC. For example, different reports may alter closing prices based on after-hours trading. Markets that conform to the Consolidated Tape Association standards report the closing price as the stock price at the close of the market, with separate designations for prices based on after-hours trading.
