That same formula failed on selecting the winning horse in the Kentucky
Derby.
And, to get closer to what I used to do, it also failed to predict Brawn
racing's success this year.

I have a list of stocks and their historical volatilities. Is there a
formula
that can be used in excel which could estimate the trading range of the
stock
for a given day ?

Thank you in advance.
