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

[chichungchoi <no_reply@xxxxxxxxxxxxxxx>]

I would like to determine which stock is more stable and less 
volatility for a long period of time, does anyone have any idea on this 
issue?
Stdev(C, 60) can be defined as a unit to determine the volatility of 
price movement for a specific length of periods, but how to determine 
the stability of this volatility for a long period of time? such as 10 
years.

If there are two stocks A and B, 
Stdev(C, 60) for A is more volatile then Stdev(C, 60) for B in term of 
price movement, but 
Stdev(C, 60) for A is more stable then Stdev(C, 60) for B for 10 
periods of time.

Does anyone know how to measure the stability of volatility?
Should I measure Stdev(Stdev(C, 60), 2500) to determine the volatility 
for 10 years? I could be wrong on this approach, does anyone have any 
suggestion?

Thank you for any suggestion
Eric
