Here's a way to buy volatility or to hedge a long portfolio by Grant C

Many investors hold long positions as August ends--some because they sell calls against stock, others because of asset allocation, still others because they aren't paying attention, etc. For those thinking about hedging a long portfolio, here's an idea that might help. For others, like myself, who are die hard volatility traders, this idea will work almost as well as options or inverse index ETFs. The VXX is the ETN of the VIX and trades about 3X the S&P. The common method of measuring volatility in the stock market is the VIX, an index based on a ratio between purchased calls vs. puts. Mostly the VIX declines when the market either rallies or goes into a period of complacency or reduced movement. Sort of what happens during the summer months as the big boys go off to the Hamptons to relax. Eventually, they come back and more often than not, they reverse August's action and jam the market into a decline. The VIX, and the VXX, goes up as a sort of "Fear" indicator (more puts being purchased than calls). This is how the Sept-Oct. period got the nick name of the "Death Season". Now, I have no idea if history will repeat itself and fireworks will replace August's inaction, but it is my nature to bet against the extremes. Since the market is at an extreme with complacency or lack of volatility, I'm interested in the other side of that trad, and will use the VXX to implement that strategy. The one thing I've learned about volatility is that it is "extreme" reverting, not "mean" reverting as most of the trading books claim. Price is much more likely to revert to the mean, or an average, and volatility seems to seek the extremes, sort of like water in a pan that is tilted back and worth so it laps at the edges.
