Max Pain Theory and the Put-Call Ratio (PCR)

This chapter explains two essential tools for options trading analysis: Max Pain Theory and the Put-Call Ratio (PCR).

Max Pain Theory​

The Max Pain Theory suggests that the price of the underlying asset will gravitate toward a point where the total pain (losses) for option holders is minimized, and for option writers is maximized at expiration. This point is called the "Max Pain" price and is often used to anticipate price movement near expiry.

Put-Call Ratio (PCR)​

The Put-Call Ratio (PCR) is a sentiment indicator calculated by dividing the number of traded put options by call options.

  • A high PCR indicates bearish sentiment.
  • A low PCR suggests bullish sentiment.

How It Works​

  1. Max Pain Calculation:

    • Aggregate the total loss for all outstanding call and put options at each price level.
    • Identify the price where the least amount of loss occurs (the "Max Pain" price).

  2. PCR Analysis:

    • Evaluate the ratio of puts to calls over time to gauge market sentiment shifts.

Examples​

Example for Max Pain​

Imagine a stock trading at ₹100. By calculating Max Pain, you may find that the maximum loss for option holders is minimized at ₹95. This could imply that the stock will drift toward ₹95 as expiration approaches.

Example for PCR​

  • If the PCR value is 1.5, it suggests that more puts are being traded than calls, indicating a bearish outlook.
  • If the PCR value is 0.5, it means more calls than puts are being traded, suggesting a bullish sentiment.

When to Use These Tools​

  • Max Pain: Best used around options expiration to anticipate potential price moves.
  • PCR: Useful for assessing overall market sentiment and identifying potential reversals.

Advantages and Disadvantages​

Max Pain​

Advantages:

  • Helps predict price behavior near expiration.

Disadvantages:

  • Not always reliable due to market manipulation or unexpected events.

PCR​

Advantages:

  • Provides a quick gauge of market sentiment.

Disadvantages:

  • Can be misleading in highly volatile markets.
