What is Put Call Ratio?

Last Updated on December 13, 2023 by BFSLTeam BFSLTeam

The Put-Call Ratio is like the barometer of the stock market, giving investors a sense of the prevailing market sentiment. In simple terms, it is an indicator that can help you gauge market mood – bullish or bearish. It’s crucial, especially in the Indian context, where market dynamics are as diverse as its culture.

In this blog, you’ll learn about the PCR ratio meaning, how to analyse it, calculate it, and why it matters. 

What is the Put-Call Ratio?

The Put-Call Ratio, or PCR as it’s commonly abbreviated, is a popular tool used by traders and investors to measure market sentiment. Simply put, it’s a quotient that reflects the volume of trading in put options versus call options. Puts are bets that a stock or index will fall, and calls are wagers that it will rise. 

When you hear traders discussing the PCR ratio, they’re talking about whether more people are betting on the market to decline or rise. A higher ratio indicates that more puts are being bought relative to calls, suggesting that investors are either expecting a downturn or are hedging against one. Conversely, a lower ratio signals that calls are the favoured choice, implying a bullish outlook.

How to Analyse PCR?

Analysing the Put Call Ratio indicator requires a keen eye on market trends and a bit of intuition. If you’re analysing the PCR, consider it in the context of recent market movements. A high PCR ratio might not always mean that the market will fall; sometimes, it’s just a sign of investors being cautious. On the other hand, a low PCR could indicate overconfidence in the market, which could precede a correction.

It’s also important to look at the PCR over time rather than at a single point. Is the ratio trending upwards or downwards? What does that say about how market sentiment is shifting? You can also compare the current PCR with historical averages to determine if it’s out of the ordinary.

Remember, the key to utilising the Put Call Ratio effectively lies in understanding its details and interpreting it within the broader market context. The Put Call Ratio shouldn’t be used in isolation; it’s one part of a broader set of analytical tools. When you use it along with other market indicators, it can lead to more informed and intelligent trading decisions.

How is PCR Calculated?

Putting it simply, the put-call ratio formula is straightforward. You divide the number of traded put options by the number of traded call options. If 200 puts and 100 calls are traded, the PCR is 2.0, indicating that for every call bought, two puts are bought.

To put it into practice, consider the daily trading volumes of options on Nifty or individual stocks listed on the National Stock Exchange. By applying the formula to these figures, you get a snapshot of the trading day’s PCR. It’s a simple yet powerful tool to have in your analytical arsenal.

Significance of Put Call Ratio

Let’s explore the significance of the put-call ratio offering you bite-sized wisdom:

1. Contrarian Indicator: PCR serves as a contrarian signal. An elevated ratio might signal that the market is due for a positive reversal, while a low ratio could hint at an impending downturn.
2. Market Sentiment: It acts as a temperature check on market sentiment. High PCR suggests bearish sentiment, while low PCR points to bullish sentiment.
3. Overbought/Oversold Levels: Extreme PCR levels can indicate overbought or oversold market conditions, offering potential entry or exit points.
4. Risk Appetite: The PCR can reflect the risk appetite in the market – risk-averse or risk-taking.
5. Hedging Activity: It can also signify the extent of hedging activity, as more investors buy puts to protect their portfolios.

Limitations of Put Call Ratio

Despite its utility, the PCR comes with its own set of limitations.

1. Lagging Indicator: PCR is based on past transactions and thus is a lagging indicator. It reflects what has already happened rather than predicting the future.
2. Hedging vs. Speculation: The PCR doesn’t differentiate between options bought for hedging purposes and those for speculation. This can sometimes cloud its predictive power.
3. Market Noise: During periods of high volatility, the PCR can be swayed by short-term noise rather than true sentiment changes.
4. Isolation Risk: Using PCR in isolation can be misleading. It’s best utilised in combination with other market indicators and analyses.
5. Historical Comparison Limits: The effectiveness of comparing current PCR with historical averages can be limited, as market dynamics change over time.

Conclusion

The Put-Call Ratio is a vital tool in the hands of a smart investor. While it’s not a magic wand that can predict market movements with absolute certainty, it offers valuable insights into the collective psyche of market participants. In the Indian context, where the markets are as dynamic as the monsoon winds, the PCR can provide a steady perspective.

As you navigate the Indian markets, let the PCR be one of the tools you use to measure the winds of sentiment.
