Put Call Ratio — Meaning, Definition & Full Explanation

The put call ratio (PCR) is a significant financial metric that measures the relationship between the trading volumes of put options and call options. It serves as an indicator of market sentiment, where a high ratio suggests bearish sentiment and a low ratio indicates bullish sentiment among investors regarding the underlying asset.

What is Put Call Ratio?

The put call ratio is a commonly used tool in options trading to assess the market sentiment of investors. A put option grants the holder the right, but not the obligation, to sell a specific underlying asset at a predetermined price, while a call option allows the owner to buy the same asset. By calculating the put call ratio, traders can understand whether more investors are buying puts (expecting prices to drop) or calls (anticipating prices to rise). The ratio is calculated by dividing the total volume of put options traded by the total volume of call options traded over a specific period. This ratio is used not only to gauge market sentiment but also to assist traders in making contrarian investment decisions based on current market trends.

How Put Call Ratio Works

1. Collect Data: To calculate the PCR, first gather the trading volumes of both put and call options for a designated period.
2. Perform Calculation: Use the formula:
   [ \text{Put Call Ratio} = \frac{\text{Put Volume}}{\text{Call Volume}} ]
3. Interpret Results:
   • A PCR greater than 1 indicates that more puts are being traded than calls, suggesting a bearish outlook among investors.
   • A PCR less than 1 implies higher call volume compared to puts, reflecting a bullish sentiment.
4. Market Sentiment Indicator: Traders may interpret high PCR values as a potential reversal signal, indicating that a sell-off may be overextended, while low PCR could mean a buying opportunity if a rally seems excessive.
5. Using in Strategy: Options traders often use PCR data to make strategic decisions, such as timing buys or sells, as it indicates the balance of fear and optimism in the market.

Put Call Ratio in Indian Banking

In India, the put call ratio is closely monitored by market participants, particularly through platforms like the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE). The Securities and Exchange Board of India (SEBI) oversees the regulations regarding options trading in India. Institutions like ICICI Bank and SBI engage actively in derivatives trading, with the options market playing a crucial role in price discovery and hedging strategies. The put call ratio features prominently in the JAIIB and CAIIB exam syllabi, where candidates are expected to understand its calculation and implications on market sentiment. Additionally, the PCR is used by traders to evaluate the potential direction of volatility in the stock market, aiding in decision-making for investments under economic changes.

Practical Example

Ravi, a finance professional in Bengaluru, is analyzing the stock of a technology company, TechCorp Ltd. Over the past month, he notes that 10,000 put options and 20,000 call options have been traded. To calculate the put call ratio, Ravi divides the put volume by the call volume, which gives him a PCR of 0.5. This low ratio signals a bullish sentiment in the market, with more investors expecting the stock price to rise. However, Ravi also considers historical data and current events surrounding TechCorp Ltd. After a thorough analysis, he decides to enter a long position in call options, anticipating an upward movement in the stock price aligned with market sentiment.

Put Call Ratio vs Open Interest

Feature	Put Call Ratio	Open Interest
Definition	Ratio of put options volume to call options volume	Total number of outstanding options contracts not yet settled
Purpose	Gauge market sentiment	Assess liquidity and potential market direction
Calculation	(\text{Put Volume} / \text{Call Volume})	Cumulative total of opened contracts
Market Indicator Type	Contrarian indicator	Market health indicator

The put call ratio is primarily used to understand trader sentiment, while open interest provides insight into how many contracts are actively being traded, which helps gauge market liquidity. Both metrics can complement each other; for example, a high PCR with decent open interest may indicate strong bearish sentiment, while low PCR with low open interest may suggest a lack of conviction in the existing trend.
