Quantitative Mechanics

How the Structure Works

The only risk is if the stock gets pinned exactly at the higher long strike at expiration (the "valley of death").

The Call Ratio Backspread is an asymmetric volatility breakout weapon. You sell 1 lower strike call to completely finance the purchase of 2 higher strike calls for a net zero cost or small credit. If the market crashes or collapses, you keep the net credit (zero downside risk!). If the market explodes higher, you make unlimited profits from the double long calls.

Strike Selection Criteria
