Put/Call Ratio

The put/call ratio is the most widely referenced options sentiment indicator. It divides the total put volume by the total call volume for a given stock or index. A ratio below 1.0 means more calls are trading than puts (bullish leaning), while a ratio above 1.0 means more puts are trading (bearish leaning). For the overall market, the average equity P/C ratio tends to sit around 0.6-0.7.

While the P/C ratio provides a quick snapshot of sentiment, it has significant limitations when used in isolation. It treats all volume equally — $500 in far out-of-the-money lottery ticket calls carries the same weight as $50,000 in deep-in-the-money institutional calls. It also doesn't distinguish between opening and closing transactions, can't separate retail noise from institutional positioning, and lacks context for what's normal for a specific stock or sector.

Options Pilot uses the P/C ratio as just one of seven sentiment checks within the Sentiment pillar. We supplement it with OI skew analysis, volume-OI alignment, conviction quality metrics, smart money flow detection, and sector-relative comparisons. This multi-dimensional approach reveals the full story behind options flow, not just a single number. A P/C ratio of 0.48 might look bullish, but our seven-check system might reveal that the bullish signal carries only moderate conviction — valuable nuance that changes how you should trade.
