I'm currently searching for a website, free or paid, which each day ranks the highest correlation stocks, and/or etfs, Any particular favorites for those who have/do trade based on correlation. I appreciate the help.
One of the journal threads on pairtrading uses this site to get into its pairs, http://www.pairtradefinder.com/ otherwise, this one is also pretty good, http://www.csidata.com/ though the free one already listed looks great
