Russell Clark references the Price-to-Sales ratio as one input for SPX income strategies. How is it actually incorporated into strike selection or position sizing?

At VixShield, we approach SPX income trading through a disciplined, rules-based framework centered on 1DTE Iron Condors, the Iron Condor Command. Russell Clark integrates fundamental inputs like the Price-to-Sales ratio as a macro filter within the broader Unlimited Cash System rather than a direct mathematical variable in daily execution. The P/S ratio helps gauge overall market valuation and potential mean reversion risk, influencing our pre-signal calibration each afternoon. For instance, when the S&P 500's aggregate P/S sits above its long-term median of approximately 2.1, we lean toward more conservative tier selection even if VIX Risk Scaling permits all three tiers. This tempers exposure during periods of elevated valuations that historically precede larger drawdowns. Strike selection itself remains governed by our proprietary EDR indicator, which blends VIX9D and historical volatility to project the Expected Daily Range, combined with RSAi for real-time skew adjustment. On a typical day like those seen in late April 2026 with SPX near 7138.80 and VIX at 17.95, EDR might suggest a 1.16 percent range, prompting Conservative tier wings targeting a 0.70 credit, Balanced at 1.15, or Aggressive at 1.60. The P/S filter might shift us from Aggressive to Balanced if valuations signal caution, ensuring we stay within our 10 percent of account balance position sizing rule. ALVH provides the true risk backbone, layering VIX calls across short, medium, and long tenors in a 4/4/2 ratio to cut drawdowns by 35-40 percent during spikes. This integrates with Theta Time Shift, our zero-loss 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 premium without adding capital. Position sizing never exceeds 10 percent per trade, scaled further if P/S and other macro signals indicate fragility. The result is a Set and Forget methodology with no stop losses, delivering approximately 90 percent win rates on the Conservative tier across backtested periods. Signals fire reliably at 3:05 PM CST post-SPX close, avoiding PDT concerns. All trading involves substantial risk of loss and is not suitable for all investors.
