I've got the monthly standard deviation for a portfolio of stocks and I need the yearly value. Is it 'statistically allowed' to just multiply the monthly value by 12? For example:
monthly standard deviation = 5,
hence, yearly standard deviation = 60.
If not, how can I get the yearly standard deviation from the monthly value?
(I cannot recalculate because I do not have the source data).
