How is the Put Call Ratio Calculated?

To calculate the pcr in the share market, divide the open interest in a put contract on a specific day by the open call interest on the same day.

Based on Open Interests on a Specific Day.

The PCR is calculated by dividing open interest in a put contract on a certain day by open call interest on the same day.

PCR (OI): Put Open Interest / Call Open Interest 

Based on the volume of options trading.

The PCR is calculated by dividing the put trading volume by the call trading volume on a given day.

PCR (Volume): Put Trading Volume / Call Trading Volume

Put volume refers to the total number of put options initiated during a given time range. Call volume, on the other hand, represents the total number of calls made within a certain time.

Notably, the meaning of this ratio varies depending on the type of investment.

Example of Put Call Ratio

Ms. Amruta, an investor, intends to use the PCR ratio to assess the market attitude of a specific investment. The puts and calls initiated are listed below:

Type of OptionNumber Initiated

PCR is total put open interest divided by total call open interest. 

PCR Ratio = 1300/1700

                  = 0.7647 

Because the outcome is less than one, it suggests that investors prefer to buy call options over put options. It also indicates that investors expect a positive trend in the future.

Importance of Put Call Ratio

The pointers below show the relevance of PCR in brief:

  • It is a useful tool for determining current market mood.
  • PCR ratio helps traders comprehend the direction of price movement in underlying securities. As a result, they may place directional bets on orders with more ease.
  • It is essentially a contrarian signal, which allows traders to avoid the herd mentality while investing in a certain market.
  • This PCR ratio is important for analysing the overall trading behaviour of market players.  

Regardless, this derivative indication is not without its limitations. Investors must learn more about them to battle market attitudes properly. 

Limitations of Put Call Ratio

One of the most significant limitations of the PCR ratio is that it does not always capture the subtleties of market mood.

Other Limitations of this ratio include—

  • Many corporate stocks do not provide options. This makes it impossible to calculate the PCR for the majority of equities.
  • Even though it is a contrarian indication, investors should consider other important criteria before wagering on current market attitudes.
  • To achieve successful results, PCR must be used in conjunction with other strong markers.
  • Investors must understand how to correctly interpret the put-call ratio chart, as even little shifts may serve as an important signal of potential market volatility.
