Stock Research: Prices

WEB RESOURCES

This is a selected list of sites that offer free stock pricing data. While many of these have extensive historical data, this can be inconsistent (especially when a company's capital structure changes).

Yahoo! Finance
Daily, weekly and monthly open, high, low, close, volume, and close adjusted for splits and dividends. Search for a stock and then select "historical prices". Data are available back as far as 1962, depending on the stock (the earliest available date will be displayed automatically). Also covers mutual funds, indices and exchange traded funds.
Google Finance
Daily and weekly open, high, low, close and volume. Prices are adjusted for splits and dividends, but these actions are not indicated when the data are downloaded. Data are available as far back as forty years.
Big Charts
Most useful for getting a quote for a specific date. Does not offer data downloads.
