VXX or SPDR etf's optionsIf you hate how the Vix futures lag the spot Vix and want to see bigger moves in strong market moves on a more level playing field like me (I always say trading HVU is an uphill battle), then try SPY or DIA (sp500 and Dow Jones) or VXX etf's options in the US market. I once got a 50% gain in a single day on a 1.5% move in the S&P. Only for very short term and strong moves, and decay is worse than HVU over time, but I find is more "fair" than trading HVU, and even HVI to some extent.
