Stock Market Data

[mtgordon]

I'm looking for a data set that has the history stock prices for the last 10 years or so. Bigger time frame is better, but I might only get through the newer data anyway so small data might not be that bad.

I'd like to be able to sort through it and look for certain situations like "stock went down 5% in 1 day" or something like that. If it's just in excel format I can probably write something that would do that for me though.
