Here's a neat way to download stock data from Yahoo, perhaps into a spreadsheet (so you can play with the data):
http://finance.yahoo.com/d/quotes.csv?s= a BUNCH of STOCK SYMBOLS separated by “+” &f=a bunch of special tags
where some special tags are (thanks to Mike):

For example, if y'all copy and paste this URL into your browser address:
you'll get something which looks like:
"GENERAL ELEC CO",32.98,"Jun 26","21.30 - 32.98","NYSE",2.66,"Jul 25",28.55,"Jul 3","-0.21%"
whereas, to get the data already in a spreadsheet (so you can play it), you can use (for example):
Here's a spreadsheet that'll download the Yahoo data according to the tags that you specify:
You just follow steps 1, 2, 3 then 4 (click the button).
And all that info gets …?
Gets downloaded into the spreadsheet. You just have to identify the Yahoo Symbols, stick in the Yahoo Tags that define the info you want, stick in some Headings (so you know what you're getting), then click the Download Data button. You will also want to reformat the columns so that prices don't display as dates
To download the spreadsheet, click on the picture above.
See also Portfolio spreadsheet.
Data is downloaded in .csv format … that's comma-separated-values.
Some stock names include commas.
The data associated with such a stock won't look good … things gets shifted to the right. ^#$%@!&?
Solution? (as suggested by Azamul K.)
Put the name LAST … in the right-most column.
If you'd like to play with the 500 S&P stocks, you can use the spreadsheet described here. It also uses some of these tags.
