Calculating Standard Deviation (Risk) for Portfolio

[Bailing-Bob]

Can anyone direct me to a website where I can enter a model portfolio of mutual funds and determine the Standard Deviation of the portfolio over different time periods. I have no problem finding the Standard Deviation for the individual funds but I want to determine the SD for different portfolios as a whole.

Thanks.

Thanks. Just checked it out. Looks promising. Limiting factor is risk data only goes back to 1999.

Since I'm with Etrade, it's build into my account options. I played with it a little but wasn't too excited about it.
