Experimental Stock Market Data

This is an experimental page that currently provides a link to the latest stock market information. It is updated automatically, usually between 10:00 p.m. EDT and 1:00 a.m. EDT, from an email source in California to reflect the current day's closing information. It consists of general market news and quotes for selected stocks. Not all stocks are included here; see here for the ticker symbols of the included stocks.

Stock prices are "Deemed reliable, but never guaranteed." For reliable stock prices consult a licensed stockbroker or a reputable financial newspaper or service. For more information about the source of these quotes, or to get on the mailing list to receive these quotes directly please contact martin.wong@eng.sun.com. The charts available below are part of a free value-added service provided as an experiment by Mark Torrance at the M.I.T. Artificial Intelligence Lab.

Please send mail to the stockmaster at the address below if any of the following is true:

If you know the name of a company which this service tracks, currently listed as "(unknown)"
If you know the name and symbol for a mutual fund which you would like to have added to the mutual fund charts page
If you have specific suggestions for ways to improve the service

I cannot guarantee a response to your message; usage of this service has increased dramatically since it was mentioned in an article in the Washington Post business section on April 10, 1994 (click here to read the article).

Please do not send mail to request that this service track a given stock that is not provided in the source data; I have no control over which stocks are provided.

Note: You may find it helpful, if you are using NCSA Mosaic for X-windows, to set your fixed font to a smaller size for viewing this and other 80-column ("preformatted") text in the default Mosaic document view. You can do this by inserting the text

Mosaic*plainFont: *adobe-courier-medium-r-normal-*-12-*

into your .Xdefaults file.
