how do i calculate an annualized gain standard deviation? i have monthly and quarterly gain standard deviation values, but is there a basic/direct equation that allows me to calculate the annualized gain standard deviation from either/or the monthly and quarterly values?

For statistically independent random variables, you can add variances. You can test to see if adding mothly variances will give you a quarterly variance.

I have also been trying to find this solution. Several years ago I had a number to use to relate the two SD's so I know it exists. Did you come up with an answer yet?

FYI as I looked further, I found this article which discusses the monthly vs annual issue std dev issue. Hope this helps.
