Is Volatility an Asset Class?

Others have weighed in on whether volatility should be considered an asset class. From the point of view of a long term investor it clearly doesn’t make sense to buy and hold volatility. (In that sense, it is the ultimate cyclical asset class and we should be glad we don’t live in a world of ever increasing volatility!). However, in terms of the diversification benefit for a portfolio, the VIX does exhibit low (and negative) correlation with many of the major asset classes. The table below shows the correlation matrix for major asset classes over the past 750 days, a period during which the VIX had negative correlation with US stocks and real estate and no correlation with European stocks. Notice, though, that a similar diversification benefit could probably have been achieved with a combination of treasuries and bonds.
