I'd like to know your thoughts on the proper way to trade volatility. For example, I was taking a look at VXGN and was wondering what would be the best strategy to implement in order to capture an expected rise in volatility? IV is currently around 73 and lets say I expect volatility to increase to 90. Is a straddle the best strategy? How about a strangle? Should you ensure you're delta neutral? What is absolute critical in this trade? What makes this a good or bad trade? I'm not interested in playing this one, only wanted to use it as an example. I know I'm new at this greek thing, but I'm trying to learn. Many thanks for your input.
