In early 2021, GameStop became the poster child of the meme stock frenzy. What started as a retail-driven rally, fueled by social media discussions on platforms like Reddit, turned into a full- blown gamma squeeze. As large numbers of call options were purchased, market makers were forced to buy up shares to cover their risk, driving the stock price higher.
This sudden price increase put immense pressure on short sellers who had bet against the stock. As the price continued to rise, they were forced to cover their positions by buying back shares, pushing the stock even higher in what became a vicious cycle of short covering and gamma hedging.
This phenomenon piqued the curiosity of traders and investors alike, as it demonstrated the power of social sentiment and how short interest could trigger explosive price movements. The same pattern was repeated with AMC and other meme stocks, showing that gamma squeezes are not just rare events—they can happen anytime these key elements align. Understanding gamma squeezes is crucial for traders looking to capitalize on these sudden price movements—or avoid being caught on the wrong side of a trade.
A gamma squeeze occurs when large amounts of call options are bought on a particular stock, forcing market makers to buy the underlying stock to hedge their positions. As they buy shares, the stock price rises, which in turn causes more call options to enter the money, leading to more hedging by market makers, and thus even more buying pressure. This chain reaction drives the stock price higher and higher.
In simpler terms:
The term “gamma” refers to the rate of change in the delta of an option relative to changes in the underlying asset’s price. Delta is the amount an option’s price changes for every $1 movement in the stock price. When options move into the money, gamma increases, which leads to higher demand for the stock as market makers adjust their delta hedging strategies.
What separates a gamma squeeze from regular price movements is its self-reinforcing nature. Once it starts, it can quickly escalate into an exponential price increase, creating opportunities for those who are positioned correctly but also devastating losses for those caught short.
Recognizing the signs of a gamma squeeze before it fully unfolds can give traders a significant advantage. Here are the key elements to look for:
One of the clearest indicators of a potential gamma squeeze is a sharp increase in call options activity. Traders who purchase call options are essentially betting that the stock price will go up, but this also forces market makers to hedge their exposure. As the number of call options increases, so does the pressure on market makers to buy the stock.
Look for stocks where out-of-the-money (OTM) call options are being purchased in unusually large quantities. This sudden spike in call options increases the likelihood that market makers will need to buy shares, initiating the gamma squeeze.
Implied volatility reflects the market’s expectation of future price movements. When traders expect large price swings, implied volatility rises. If you notice that a stock has abnormally high implied volatility, especially in its options market, it could be a sign that traders are anticipating a major move.
This high volatility signals that a gamma squeeze could be forming. Elevated IV, particularly in conjunction with increased call option buying, is often a precursor to the event.
Gamma squeezes often affect stocks with high short interest, where a significant percentage of the stock has been borrowed and sold by short sellers who are betting on the stock’s price to fall. When the stock price rises due to the gamma squeeze, short sellers are forced to buy back shares to cover their positions (called short covering), driving the price even higher.
A key indicator of a potential gamma squeeze is when a stock has both high short interest and heavy options activity. This combination creates the perfect storm for a price explosion.
Open interest is the total number of outstanding options contracts. Monitor the open interest on key strike prices (where call options are being purchased) relative to the current stock price. If the stock price moves toward those strikes and crosses them, market makers will be forced to buy more shares, increasing the gamma squeeze pressure.
Tracking open interest and its relation to stock prices gives insight into where the most significant buying might occur as market makers hedge their positions.
Once you’ve identified the potential for a gamma squeeze, the next step is determining how to use this knowledge to your advantage. Here’s how you can act:
If you’ve identified a stock with high call option volume, elevated implied volatility, and significant short interest, you may be looking at a potential gamma squeeze. One common strategy is to purchase call options yourself, betting that the squeeze will push the stock price higher. However, timing is critical—entering too early or too late can result in losses.
A gamma squeeze often forces short sellers to cover their positions by buying back shares, causing the stock price to spike even more. Traders who identify a developing gamma squeeze early can take advantage by going long before the short covering accelerates.
In cases where the gamma squeeze leads to a sharp and rapid rise in prices, there are often opportunities to take profits quickly, as the rally can end just as abruptly as it began.
Social sentiment has played a huge role in recent gamma squeezes. Keeping track of discussions on platforms like Reddit, Twitter, or stock forums can provide early clues about stocks experiencing sudden retail interest. If retail traders are talking up a stock while call option volume rises, a gamma squeeze may be forming.

Gamma squeezes offer both opportunities and risks. Understanding the mechanics behind these sudden, dramatic price movements can give traders an edge in highly volatile market conditions. While gamma squeezes can lead to substantial gains, they require a deep understanding of options markets, short interest, and timing.
By utilizing data analytics, tracking options flow, and monitoring market sentiment, traders can position themselves to capitalize on gamma squeezes when they occur.
