Options traders watch the market-wide balance of put versus call volume as a contrarian sentiment gauge — extreme readings often mark short-term sentiment extremes rather than reliable forecasts.
How it works
Dividing total put volume by total call volume gives the put/call ratio; conventional thresholds read a ratio above roughly 1.0 as bearish positioning and below roughly 0.7 as bullish positioning.
What this does not include
This does not include open interest (a separate, sometimes more informative measure than volume alone), or the distinction between equity-only and index put/call ratios, which behave differently since index options are more commonly used for hedging.

Frequently asked questions
Why is the put/call ratio often read as a contrarian indicator?
Extreme bearish or bullish crowd positioning has historically often preceded a reversal, making an extreme ratio reading sometimes more useful as a “too much fear” or “too much greed” signal than a literal directional forecast.
Is a rising put/call ratio always bad news for the market?
Not necessarily — a rising ratio partly reflects hedging activity (investors buying puts to protect existing long positions), which doesn’t always signal a bearish directional bet.
What ratio level is considered “normal”?
It varies by underlying and time period, but many practitioners treat a roughly 0.7-1.0 range as neutral, with readings outside that band treated as more notable sentiment extremes.
