Here's a tweak suggestion, unless FM already does this and I missed it. It's frivolous, but I'm just curious enough to want to know the answer.
Suppose I'd like to see how well my portfolio's performance over a time period correlates with some of the major indexes, such as DJIA, S&P500, Russell 2000, etc. IF I could get my hands on a file of how those indexes have performed, would FM do the statistical math for me, and show me a correlation coefficient for my portfolio vs. each of those indexes?
