Understanding the Put-Call Ratio: A Key Indicator for Market Sentiment and Trading Strategies

How is the Put-Call Ratio Calculated?

The PCR can be calculated through one of two primary methods: open interest or trading volume. The open interest method is simply the total open interest puts divided by the total open interest calls for the day.

The volume method is the total trading volume of puts divided by the total trading volume of calls. For example, if 900 put options were initiated and 1500 call options were initiated on the same day, the PCR would be 0.6, which signals a bullish scenario because more calls are being purchased.

Understanding the Put-Call Ratio

Options traders bet on market movement using put options to short the market or take a bearish position, while call options are used to take a long position on the market.

An increase in put buying, or an increased bearish sentiment, would indicate a put-call ratio (PCR) greater than 1. A PCR that is less than 1 would reflect bull trends and increased call buying.

An PCR of 1 is not a great sentiment indicator, as call options generally are purchased more than puts. For equity options, a good gauge of market sentiment would be an average PCR of around 0.7.

When the PCR is greater than 0.7 or equal to 1, there is an increased bearishness, as investors hedge their portfolios against being hit by selling. When the PCR is lower than 0.7, especially closer to 0.5, it reflects a more bullish sentiment or outlook on equities.

Why the Put-Call Ratio Matters?

The PCR acts as a gauge of general market sentiment, whether investors are either bullish or bearish and even foreshadows potential price action, suggesting whether traders believe prices will move higher or lower.

Typically used as a contrarian indicator, extreme PCR levels can herald impending reversals in the overall market. For example, a high PCR may indicate an overbearing market ready to rebound, while a low PCR may suggest an overly optimistic sentiment that will lead to a market correction.

In addition, PCR also tracks trading habits, investor risk attitude, and changes in investor sentiment. Tracking these trends alone can help provide investors with insight into their trading decisions with helpful information, while at the same time modifying trading strategies to current market conditions.

What is a Good Put-Call Ratio?

There is no definitive “good” PCR value; it depends on market sentiment. However, a popular benchmark value is simply one of 0.7. Any value greater than 0.7 or more than 1 simply indicates bearishness, while values falling below 0.7 - particularly around 0.5 - signify bullishness.

Additionally, one must watch both put and call volumes to avoid misinterpreting the ratio - for instance, a decline in call volume can easily inflate the ratio with a market sentiment that is not really legitimately bearish.

FAQs

What is PCR?

The Put-Call Ratio (PCR) is one of the most important indicators of market sentiment that is always taken into consideration. This indicator quantifies the relationship between the trading volume or open interest of put options and that of call options. It can be calculated in two ways: by dividing Put Volume by Call Volume or by dividing Put Open Interest by Call Open Interest.

What is a high PCR?

When the Put-Call Ratio (PCR) is high, say in most cases above 1, it reflects that the traders are buying more put options than call options. This is taken to mean that generally the market is afraid of a downturn and that the traders are already moving to the safe side by taking bearish positions.

A Put-Call Ratio (PCR) greater than 1 indicates that more put options are being traded than call options. This often denotes a bearish market since traders are indulging in the speculative activity of assuming a decline to sell the stock or are hedging their investments through options buying.

What is PCR is greater than 1?

To explain a Put-Call Ratio (PCR), traders first get the number of put options and then get the number of call options. This calculation results in a number (ratio) that, if above ,1 indicates bearish sentiment, while if below 0.,7 indicates bullish expectations.

How to analyze the PCR ratio?

A Put-Call Ratio (PCR) of 1 implies that the market is neutral because investors are selling (buying) an identical quantity of put and call options. Different traders have different opinions in this regard, but most of them consider a ratio below 0.7 to be a strong bullish signal, whereas a PCR above 1 is usually interpreted as a strong bearish signal.
