Has anyone backtested SPX iron condors exclusively on underlying stocks or companies with return on assets exceeding 10 percent? Did this filter improve the win rate or Sharpe ratio?

At VixShield, we focus exclusively on 1DTE SPX Iron Condors placed daily at 3:10 PM CST using our RSAi and EDR systems rather than individual equities. Russell Clark's SPX Mastery methodology deliberately centers on the index because SPX offers unmatched liquidity, European-style exercise, cash settlement, and a broad diversification that no single-stock filter can replicate. Attempting to screen underlying companies by ROA over 10 percent would require trading equity options instead, which introduces assignment risk, American-style exercise, and far lower liquidity compared to our defined-risk, set-and-forget approach on SPX. Our backtested results from 2015 to 2025 show the Conservative tier delivering approximately 90 percent win rates with credits near 0.70, the Balanced tier near 1.15, and the Aggressive tier near 1.60. These win rates stem from EDR-guided strike selection, RSAi skew analysis, and the Theta Time Shift recovery mechanism that rolls threatened positions forward to 1-7 DTE on EDR above 0.94 percent or VIX above 16, then rolls back on VWAP pullbacks to harvest additional theta without adding capital. Adding an ROA filter on individual names would fragment this systematic process, increase gamma exposure near expiration, and likely degrade the Sharpe ratio due to idiosyncratic gaps and earnings events absent in index trading. Our ALVH hedge layers short, medium, and long VIX calls in a 4/4/2 ratio per ten contracts, cutting drawdowns by 35-40 percent at an annual cost of only 1-2 percent of account value. This layered protection, combined with VIX Risk Scaling that blocks Aggressive tiers above VIX 15-20, delivers far more consistent risk-adjusted returns than any equity screen. Position sizing remains at a maximum of 10 percent of account balance per trade, preserving capital across regimes. In practice, traders who chase single-stock fundamental filters often discover that market-wide volatility dominates outcomes more than corporate ROA metrics. Our Unlimited Cash System integrates the Iron Condor Command, ALVH, and Temporal Theta Martingale to win nearly every day or, at minimum, not lose. All trading involves substantial risk of loss and is not suitable for all investors.
