Hi
The firm-specific volatility of earnings,is calculated as the standard deviation of Earnings over the most recent 5 years. This should give a firm specific measure of earnings volatility.
I think this is simple to code, but I am not sure how to construct a loop for that ?
I would appreciate your help
Thanks
