ℹ️ INFO LL-309: Iron Condor Optimal Control Research

🚨 What Went Wrong

Date: 2026-01-25 Category: Research / Strategy Optimization Source: arXiv:2501.12397 - "Stochastic Optimal Control of Iron Condor Portfolios"

🔬 Root Cause

• Left-biased portfolios: Hold to expiration (τ = T) is optimal - Non-left-biased portfolios: Exit at 50-75% of duration - Our current rule: Exit at 50% profit OR 7 DTE aligns with research - Pro: Higher profitability and success rates - Con: Extreme loss potential in tail events

✅ How We Fixed It

• Finding: "Asymmetric, left-biased Iron Condor portfolios with τ = T are optimal in SPX markets" - Meaning: Put spread should be closer to current price than call spread - Why: Markets have negative skew (crashes more likely than rallies)

📈 Impact

• Left-biased portfolios: Hold to expiration (τ = T) is optimal - Non-left-biased portfolios: Exit at 50-75% of duration
