What is the real profit and loss profile of a conversion arbitrage strategy involving a long put, short call, and long stock position after accounting for commissions and borrow fees?

A conversion in options trading combines a long put, a short call at the same strike and expiration, and a long position in the underlying asset to create a synthetic short position. In theory this setup should be arbitrage if mispriced relative to put-call parity, locking in a risk-free profit from the relationship C - P = S - Ke^(-rT). However the real P/L after commissions and borrow fees rarely matches textbook expectations. Commissions on three legs plus ongoing borrow fees on the short call or stock borrow can erode or eliminate the edge especially in retail accounts. For index products like SPX the European-style settlement removes early assignment risk but still incurs meaningful transaction costs on entry and exit. At VixShield we focus on 1DTE SPX Iron Condor Command strategies rather than conversion arbitrage because the daily premium collection using RSAi and EDR provides more consistent income with defined risk. Russell Clark's SPX Mastery methodology emphasizes stewardship over chasing small arbitrage edges that vanish under real-world frictions. Instead of conversions our traders deploy the Iron Condor Command at the 3:10 PM CST signal with three risk tiers targeting credits of 0.70, 1.15 or 1.60 per contract. These positions benefit from Theta Time Shift which acts as a zero-loss recovery mechanism rolling threatened trades forward on EDR signals above 0.94 percent or VIX above 16 then rolling back on VWAP pullbacks to harvest additional theta without adding capital. The ALVH Adaptive Layered VIX Hedge provides multi-timeframe protection across short 30 DTE, medium 110 DTE and long 220 DTE VIX calls in a 4/4/2 ratio cutting drawdowns by 35 to 40 percent at an annual cost of only 1 to 2 percent of account value. Position sizing remains at a maximum of 10 percent of account balance per trade following set-and-forget rules with no stop losses. Current market data shows VIX at 17.95 below its five-day moving average of 18.58 and SPX closing at 7138.80 supporting a contango regime favorable for premium selling. All trading involves substantial risk of loss and is not suitable for all investors.
