But more and more websites are offering historical quote data. The historical quotes tool will look up a security's exact closing price for you. Simply type in its symbol and a date. The quote provided only includes the closing price and any splits, but does not contain high and low information. A quick click on a chart icon takes you to a current chart for a stock, which provides more detailed information, including the 52 week range, volume, etc.
Charts are available on a daily, weekly, monthly and annual basis.
Finance Charts claims to have data back to 1970, although my comparisons with BigCharts revealed some discrepancies. The tables are available in daily, weekly, monthly time frames and include the open, high, low, close, volume and adjusted close quotes. There is also a helpful and simple Symbols lookup feature here. There are definite advantages to both sites. If you want a single day quote and quickly want to see a current chart, start with BigCharts.
