What Greeks are neutralized in a conversion arbitrage strategy consisting of a long put, short call, and long stock? How tight must the pricing be for the trade to be worthwhile?

A conversion arbitrage strategy, defined as long put plus short call plus long stock at the same strike and expiration, creates a synthetic position that is theoretically risk-free when executed at fair value. This setup is the textbook definition of put-call parity in action. The position neutralizes delta completely because the synthetic short stock created by the short call and long put exactly offsets the long stock exposure. Gamma is also neutralized as the long put and short call have identical gamma values that cancel each other. Vega exposure nets to zero for the same reason since both the put and call share equivalent sensitivity to implied volatility changes. Theta and rho become the primary residual exposures, though in a true arbitrage these are minimal and predictable. In practice, the conversion profits from even tiny mispricings between the options and underlying, often measured in pennies per contract. Russell Clark emphasizes in his SPX Mastery methodology that while such pure arbitrage is rare in the highly efficient SPX market, understanding these relationships sharpens intuition for daily 1DTE Iron Condor Command setups. At VixShield we focus on the Iron Condor Command using EDR for strike selection and RSAi for real-time premium optimization across Conservative, Balanced, and Aggressive tiers. The ALVH hedge layers provide the real-world protection that synthetic parity cannot, cutting drawdowns during VIX spikes above 16. With current VIX at 17.95, we remain in a regime where Conservative tier entries at approximately 0.70 credit remain favored. The pricing must be extraordinarily tight for conversion arbitrage to be worthwhile after transaction costs, typically requiring at least a 0.05 to 0.10 edge per contract on SPX to overcome commissions and slippage on a position sized to no more than 10 percent of account balance. Larger edges are almost never available in index options. Instead of chasing fleeting arbitrage, VixShield traders apply the same Greeks awareness to maintain delta-neutral, vega-aware Iron Condors that benefit from Theta Time Shift recovery mechanics. All trading involves substantial risk of loss and is not suitable for all investors.
