Quantitative Mechanics

How the Structure Works

Short Futures + Long Call replicates a Long Put, which offsets the Short Put.

A Reversal (Reverse Conversion) is the opposite of a Conversion. You short the underlying futures, buy an ATM Call, and sell an ATM Put when the Put is trading at an unjustified premium to the Call.
