Only a moron...Would play hvu on margin. HVU is not a stock it is an etf that aimes on 2X the vix index. With the run on the s and p 500 its hard to say where this goes. But at the bottom it doesnt go far. Once people come to there senses and realize that calls and puts are the way to go to protect there gains then it will climb a bit.
IMO watch it like a hawk. But dont freak out to bad as it bumps and burns everyday. Have a feel for the world market and buy and hold when you call bs.
