1. Measuring Derivatives Market Positioning
The Put/Call Ratio (PCR) measures the relative trading volume or open interest of put options (bearish bets or downside hedges) compared to call options (bullish bets or upside speculation).
2. Equity vs. Index Put/Call Ratios
| Metric | Typical Range | Market Character & Usage |
|---|---|---|
| Equity Put/Call Ratio | 0.50 – 0.90 | Reflects single-stock retail and speculative trader positioning. Extreme lows (< 0.50) signal euphoria; highs (> 0.95) signal panic. |
| Index Put/Call Ratio (Cboe) | 1.00 – 1.60 | Reflects institutional hedging on S&P 500 (SPX) and Nasdaq (NDX). Ratio normally exceeds 1.0 due to permanent portfolio insurance demand. |
3. Contrarian Sentiment Timing
The Put/Call Ratio functions primarily as a contrarian indicator. When the 10-day moving average of the Total Put/Call Ratio surges to multi-year highs, excessive pessimism indicates that downside hedges are fully saturated, setting the stage for aggressive short-covering rallies.
