Not sure if this has been discussed already but, It appears that www.market-topology.com stopped providing the correlation numbers for "free" (unless i'm missing something here...). do you guys know of any other sources where i can get this info for free? Any help would be greatly appreciated. thanks!
They offer a free two week trial that you can use to look for ideas. Then just download daily price data into excel and use it to calculate correlations. This way you can calculate the numbers over any time frame as well. Corey
I went to Google and found the cached pages. It still works but the data is only updated through January 25th 2002. The link is: http://www.market-topology.com/cgi-bin/createminimap.cgi?market=NY&imgtype=checked&name= You get a page asking you to enter the correct symbol. Not sure how long that will work though.
