Cracking the Code of Gamma – Option Greek

Options trading is a powerful tool for investors to protect their positions, generate income, or speculate on the future movements of financial assets. However, successful trading in options demands a solid grasp of various factors that can affect your trades. One of these critical factors is the option Greek known as Gamma.

Gamma measures how much an option’s delta will change when the price of the underlying asset moves by Rs 1. In simpler words, it helps us comprehend how sensitive an option’s price is to changes in the underlying asset’s price. Let’s break this down further.

Delta and Gamma Relationship

Delta is another important option Greek that gauges the change in the option’s price concerning a Rs 1 change in the underlying asset’s price. However, the delta itself can change as the asset price moves. This is where Gamma comes into play. Gamma tells us how much the delta will change as the asset price changes.

Know The Power of Delta – Option Greeks

Here’s an example to illustrate the concept:

Imagine you are a trader on Dalal Street, India’s prominent financial hub, and you have purchased a call option on a stock. This call option has a delta of 0.50 and a gamma of 0.05. The stock is currently trading at ₹1000.

  • Initial State: The call option’s delta is 0.50, which means it’s expected to increase by Rs 0.50 for every Rs 1 increase in the stock price.
  • Stock Price Increases: If the stock price rises to Rs 1,001, the delta will increase to 0.55. Your option’s price will increase by Rs 0.55, resulting in a profit.
  • Stock Price Decreases: Conversely if the stock price falls to Rs 999, the delta will decrease to 0.45. Your option’s price will decrease by Rs 0.45, resulting in a loss.

In this example, Gamma reveals that the delta of your option is not constant. It changes with the underlying stock’s price movement. A higher gamma implies a steeper change in delta, indicating that your option is more sensitive to price changes in the underlying asset. This can be both an advantage and a disadvantage depending on your trading strategy.

Practical Implications

Understanding Gamma is crucial for options traders because it can affect risk management and strategy decisions. Options with higher gamma demand more attention and careful monitoring, as they can lead to rapid changes in delta and price.

For instance, if you are pursuing a steady, cautious strategy, you might prefer options with lower gamma. Conversely, if you seek higher-risk, higher-reward opportunities, options with higher gamma might be more attractive.

Conclusion

In conclusion, Gamma is a fundamental element of options trading, particularly for those on Dalal Street and elsewhere. It helps traders comprehend how the sensitivity of their options changes with shifts in the underlying asset’s price. By grasping the dynamics of Gamma, you can make more informed choices, manage risk effectively, and potentially enhance your trading success.
