If I were a smart guy, I would have funds available for opportunities like TVIX this week. It is ~20 today. ANY disruptions in the market in the coming days/weeks and this goes back up to 30 and beyond. Buy at 20, set a limit sell at 30, and walk away. It always goes up faster than it comes down. A 50% gain 'in the bank'. A no brainer actually.
I am off to scrape up some cash for this before its too late. Might be some loose change in the sofa cushions...
