It is not a simple matter to translate the VIX index into an ETF product that investors can trade on the open market. VIX options trade as monthly contracts, meaning that every 30 days, the front-month contract will expire. A fund like the ETF VXX must therefore close out its contracts each month and roll them over into the next month's contract. Because uncertainty and fear generally increases the further out time you go, later contracts tend to be more expensive than near-term contracts. This phenomenon is known as Contango. The opposite situation, Backwardation, occurs when subsequent contracts trade at a discount to the front month contract. If the underlying option strip is trading in Contango, the fund effectively pays a premium each month to roll over its contracts. Over time, depending on the magnitude of the Contango, this eats away at the fund, regardless of the performance of the index that the ETF is designed to track. The table below uses data on ETF holdings and degree of contango/backwardation in the Futures market to calculate gains or losses due to rollover.
The leveraged volatility ETFs--which include TVIX, TVIZ, and UVXY--are particularly dangerous trading vehicles. Not only do they suffer double the rollover losses (or profits, in the rare occasions that the Futures are in backwardation), but they also underperform against their 1x counterparts due to the mathematics behind the leveraging process itself. See this article for an in-depth explanation of this phenomenon. The chart and tables below calculates this decay over the past month.

The Hybrid Score is a calculation to determine profitability of volatility ETFs. The score takes into account the two primary determinants of profitability of these ETFs: Mean Reversion and Contango. Mean Reversion is the principle that while volatility make spike or slump, there is a strong tendency for volatility to quickly return to a baseline with the VIX near 20. When VIX futures contracts rise significantly above this level, the odds increase that the VIX will drop over the longer term and when the VIX drops below 20 during tranquil periods, the odds favor a return to higher levels of volatility as investors become less complacent. Contango is the spread between futures contracts and results in rollover-associated losses to fund-holders (or profits to shortsellers). Higher Hybrid scores are associated with elevated levels of volatility and large Contangos and favor those investing in inverse ETFs or short volatility. Lower Hybrid Scores are associated with low volatility and small contangos or backwardation, all of which favor those betting on increased volatility. Using these scores, the historical performance of all volatility ETFs based on current hybrid scores is calculated to determine investing strategies.
