Quantitative Mechanics

How the Structure Works

Theta and Vega of the long call and short put cancel each other out completely, leaving pure linear Delta exposure.

Synthetic Long Stock is a pure synthetic replication tool based on Put-Call Parity. Buying an ATM Call and selling an ATM Put at the same strike creates an exact Delta = +1.00 position that moves tick-for-tick with the underlying, with zero theta decay.
