What is the Put Call Ratio?

Put/Call ratio (PCR) is a popular derivative indicator, specifically designed to help traders gauge the overall sentiment (mood) of the market. The ratio is calculated either on the basis of options trading volumes or on the basis of the open interest for a particular period. If the ratio is more than 1, it means that more puts have been traded during the day and if it is less than 1, it means more calls have been traded. The PCR can be calculated for the options segment as a whole, which includes individual stocks as well as indices.

How is PCR Calculated?

The interpretation of this ratio differs as per the type of investor. PCR is calculated by two methods which are as follows:
a. Based on Open Interests of a specific day
PCR is calculated by dividing the current open interest in a Put contract on a specific day by the open Call interest on the very same day.
PCR (OI) = Put open interest/Call open interest

b. Based on the volume of Options trading
Here, PCR is calculated by dividing the total Put trading volume by the total call trading volume on a specific day
PCR (Volume) = Put trading volume/Call trading volume
Put volumes are the financial market indicator for the total initiated Put option over a specific time frame. Furthermore, Call volumes are used to indicate the total initiated Call options over that period.
