What is the Put Call Ratio?

The put call ratio (PCR) is a technical indicator used in options trading to measure market sentiment. It is calculated by dividing the number of traded put options by the number of traded call options in a given period.

Formula:
Put Call Ratio = Total Put Volume / Total Call Volume

• Put Options are contracts that give the holder the right to sell an asset at a specified price.

• Call Options are contracts that give the holder the right to buy an asset at a specified price.

So, when the put call ratio is high, it means more investors are buying puts than calls — often a sign that investors are bearish (expecting the market to fall). Conversely, a low PCR suggests more calls are being traded, showing a bullish (positive) market outlook.

How to Interpret the Put Call Ratio?

Here’s a basic guideline for interpreting the put call ratio:

• PCR > 1 – Bearish Sentiment: More puts than calls are being bought.

• PCR < 1 – Bullish Sentiment: More calls than puts are being bought.

• PCR = 1 – Neutral Sentiment: Equal interest in puts and calls.

However, seasoned traders also use this tool contrarian-style. For example, an extremely high put call ratio may actually be a bullish signal — because when too many investors are bearish, it could mean the market is oversold and ready to rebound.

Why Is Put Call Ratio Important?

1. Investor Sentiment: The PCR gives you a peek into what traders are feeling — fear or confidence.

2. Market Turning Points: Extreme PCR values often signal potential reversals.

3. Short-Term Strategy: Day traders and swing traders use PCR to time their entries and exits.

The put call ratio is most commonly applied to indices like the Nifty or Bank Nifty in the Indian market, but it can also be used for individual stocks.

How to Use Put Call Ratio in Your Strategy?

• Combine with Other Indicators: Use it with RSI, MACD, or trendlines for better accuracy.

• Watch for Spikes: Sudden changes in the put call ratio often precede volatile moves.

• Don’t Use in Isolation: PCR is a powerful sentiment tool, but it should never be your sole reason to enter a trade.

Real-Life Example

Let’s say the Nifty 50 has a put call ratio of 1.3. This indicates a bearish mood. But if the market has already dropped significantly, this could actually be a reversal signal, hinting that a bounce-back may be coming soon.

As with all technical indicators, the key is to use the put call ratio wisely — combining it with your research, technical levels, and risk management.
