Seasonal vol patterns?

Well, at least I was able to write a program in Matlab which automatically loads data from yahoo and then calculates month HV using close/close. I also created dummy variables for each month and ran it using a simple ols for XOM. The only month which was signifcant at even the 90% level was June. It was negative. I did the same thing in HAL and the same month was negative and was signficant at the same level.

I'll have to do some more research on this and use a heteroskadistic model.
 
So did you fellas ever do anything with this whole volatility study?

I did the analysis on daily Dow data back to 1900 and found a reliable huge rise in volatility from September - November.

So I'm guessing if you did the analysis and then traded the results, you would have made a bundle in the last few months?
