Put/Call Ratio
The Put/Call Ratio is a financial indicator that measures the ratio between the trading volume of put options and call options in a specific market or on a particular asset, over a defined period.
Formula:
Put/Call Ratio = Volume of Put Options / Volume of Call Options. Interpretation: Ratio > 1: More puts than calls; indicates fear or bearish sentiment. Ratio < 1: More calls than puts; signals optimism or bullish sentiment. Ratio ≈ 1: Balanced market sentiment.
Use in Trading: The Put/Call Ratio gauges overall investor sentiment. Very high values (e.g., above 1.2) often show excessive pessimism, which can precede market rebounds. Very low values (e.g., below 0.5) indicate extreme optimism, often occurring near market tops.
As a contrarian indicator, extreme readings in the Put/Call Ratio can anticipate possible market reversals. Limitations: The Put/Call Ratio is a useful sentiment tool, but it should be supported by other analysis methods, and it works best in context with additional indicators.
