Quantitative Mechanics

How the Structure Works

The only risk is if the market gently drifts and pins exactly at the lower strike at expiry.

The Put Ratio Backspread is the ultimate institutional crash hedge. You sell 1 higher strike Put to fully fund the purchase of 2 lower strike Puts for a net credit. If the market rallies or gaps up, you keep the net credit with ZERO upside loss! If the market crashes into a freefall, your 2 long puts generate explosive alpha.
