When you hear terms like “gamma squeeze” tossed around in the world of finance, it might sound like jargon from another planet. However, understanding a gamma squeeze can offer valuable insights into how stock prices can suddenly surge, and why this phenomenon is so important in the trading world. Let’s break down what a gamma squeeze is, how it works, and why it matters.
What Is a Gamma Squeeze?
At its core, a gamma squeeze is a market event that occurs when the price of a stock rises sharply due to the mechanics of options trading. It’s a bit complex, but don’t worry—we’ll walk through it step by step.
To understand a gamma squeeze, you first need to be familiar with a few concepts: options, gamma, and delta.
Options: These are financial contracts that give investors the right, but not the obligation, to buy or sell a stock at a specific price within a certain time frame. There are two main types: call options (which give the right to buy) and put options (which give the right to sell).
Delta: This measures how much the price of an option is expected to change when the price of the underlying stock changes. For example, if a stock’s price goes up by $1 and an option’s delta is 0.5, the option’s price would go up by $0.50.
Gamma: This measures the rate of change of delta. Essentially, gamma shows how much delta will change as the stock price changes. High gamma means delta changes quickly with the stock price, which can amplify price movements.
How Does a Gamma Squeeze Happen?
Initial Position: The process often starts when traders or investors take large positions in options. This can happen when they believe a stock’s price will move significantly, and they want to profit from that movement.
The Role of Market Makers: When these options are bought, market makers (the institutions that facilitate the buying and selling of options) need to hedge their positions. To do this, they buy or sell the underlying stock to balance their risk. For instance, if many call options are bought, the market makers might buy the stock to hedge.
Delta Hedging: As the stock price moves, the delta of the options changes. To keep their hedge effective, market makers need to continually buy or sell the stock. If the stock price rises, they need to buy more of it to adjust their hedge. This buying can push the stock price even higher.
Gamma Effect: Here’s where gamma comes into play. As the stock price moves higher, the delta of the options increases faster (due to high gamma). This means that market makers have to buy even more of the stock to hedge their positions. This additional buying can create a feedback loop, driving the stock price up even further.
The Squeeze: The rapid increase in stock price due to constant buying by market makers can force even more options traders to buy stock to cover their positions, creating a squeeze. This is because those holding short positions in options may need to buy the underlying stock to cover their bets.
The Impact of a Gamma Squeeze
A gamma squeeze can lead to dramatic price movements and increased volatility in a stock. This was famously observed in early 2021 with the GameStop stock saga. GameStop’s stock price surged in a classic gamma squeeze scenario, leading to huge losses for some investors and significant gains for others.
Real-World Example: GameStop
The GameStop phenomenon is a textbook example of a gamma squeeze. Here’s a simplified breakdown:
Initial Situation: Many institutional investors and hedge funds believed that GameStop’s stock price would fall, so they shorted the stock (bet on its price falling). Simultaneously, individual investors started buying call options, betting that the stock price would rise.
Options Buying: As these call options were bought, market makers had to buy shares of GameStop to hedge their positions.
Rising Stock Price: As GameStop’s stock price began to rise, the delta of the call options increased. This meant market makers needed to buy more shares, pushing the price up even further.
Feedback Loop: This cycle of buying led to an even higher stock price and more buying from market makers, creating a feedback loop that drove the stock price up dramatically.

Why Is a Gamma Squeeze Important?
Understanding gamma squeezes is crucial for several reasons:
Investment Strategy: Recognizing the signs of a potential gamma squeeze can help investors make more informed decisions. If you’re aware of how options trading can impact stock prices, you can better navigate the stock market and manage risks.
Market Volatility: Gamma squeezes contribute to market volatility. Knowing about these events can help you understand why stock prices might suddenly spike or drop.
Regulatory Insight: The impact of gamma squeezes on financial markets can lead to discussions about regulatory measures. Understanding these dynamics can inform discussions on market regulations and protections.
How to Spot a Gamma Squeeze
Spotting a gamma squeeze involves looking at several indicators:
High Options Volume: Significant trading volumes in options can indicate that a gamma squeeze might be brewing. Particularly, a surge in call options can be a warning sign.
Rapid Price Movements: If a stock’s price is moving quickly and dramatically, it could be a result of a gamma squeeze, especially if it’s happening alongside high options trading volume.
Increased Volatility: Stocks experiencing a gamma squeeze often show increased volatility. If you notice a stock’s volatility spiking, it might be worth investigating whether a gamma squeeze is occurring.
Conclusion
A gamma squeeze is a fascinating and complex phenomenon in the financial markets, driven by the interplay between options trading, delta, and gamma. While it can lead to dramatic price movements and increased volatility, understanding how it works can give investors valuable insights into market behavior and risk management. By being aware of the signs and mechanics of a gamma squeeze, you can navigate the financial markets more effectively and make more informed investment decisions.
In summary, a gamma squeeze is a powerful reminder of how interconnected financial markets can be and how intricate the mechanisms behind stock price movements can be. Whether you’re an investor, trader, or simply interested in financial markets, understanding a gamma squeeze is a crucial piece of the puzzle in grasping how stock prices can sometimes skyrocket or plummet in seemingly inexplicable ways.
