[EquisMetaStock Group] Re: How to determine the stability of volatility for a long periods of time?

Thank Jose for your reply

In comparing two different stocks A & B with different level of 
pricing, ATR can be used to determine each volatility, but I would 
like to find out which stock is more stable [less volatile] in term 
of their volatilities, which does not mean to remain constant in 
volatility, but to remain the characteristics in volatility. 
Do you have any suggestion?
Thank you for any suggestion
Eric
