VXX is moving up so fast and without pause that the system is having trouble generating any "add-on" buy signals, even on the 15 minute model. With VXX touching $46, its calls on all strikes and all weekly/monthly expirations are putting in 40% returns today. I'm buying the Jan 4th $50 call for an imminent crash, and the Jan 18th $50 calls for a slow-motion crash, spreading my money equally. These are highly speculative positions, but in a worst case market scenario, they will reward the risk taken. Jan 4th $50 calls -----> $1.60 = +45% Jan 18th $50 calls ----> $2.85 = +40%
