For what its worth, I reviewed some seasonal characteristics about volatility from the end of August thru September. The stats are worth some further investigation. In each of the previous three years, the volatility low was made in the third week of August and the peak was typically made with six weeks, here are the stats and ensuing highs...(NOTE: This is only based on the VIX, just a raw pen and paper calculation, so I dont tick off any of the scientists on the site)...
2001: 8/27(low) 21.94 9/21(high) 57.31 +161.21%
2000: 8/28(low) 18.13 10/13(high)36.74 +102.65%
1999: 8/25(low) 20.31 9/24 (high) 32.33 +59.88%
1998: 8/07(low) 25.28 9/01(high) 53.08 +109.97%
So, in three of the last four years the VIX has bottomed in the final week of August before rising thru September and typically October...So I would say odds favor rising volatility and long volatility strategies
