gamma squeeze

In the world of stock trading and investing, terms like “short squeeze” and “gamma squeeze” have been making headlines, leaving many wondering what these phenomena entail. In this article, we’ll delve into the concept of a gamma squeeze, shedding light on what it is, how it happens, and the implications it carries for traders and investors.

What is a Gamma Squeeze?

A gamma squeeze is a market phenomenon that occurs when the rapid buying of options, particularly call options, leads to a significant increase in the price of the underlying asset.

In essence, it’s a self-fulfilling prophecy: as traders purchase call options, market makers who sold these options must hedge their positions by buying the underlying asset. This increased demand for the asset can drive up its price. As the price rises, more call option buyers are attracted, leading to further purchases and price escalation. This positive feedback loop creates a gamma squeeze.

Gamma squeezes are often associated with heavily shorted stocks, as the forced buying of the underlying asset by market makers can result in substantial losses for short sellers. Traders and investors closely monitor the options market and gamma exposure to identify and potentially profit from gamma squeezes.

To comprehend a gamma squeeze, we must first understand the term “gamma” in the context of options trading. Gamma is one of the Greek letters used in options pricing models, and it represents the rate of change of an option’s delta concerning changes in the underlying asset’s price.

  • Delta: Delta measures the change in the option’s price concerning changes in the underlying asset’s price. It essentially quantifies the option’s sensitivity to movements in the stock price. Delta can range from 0 to 1 for call options and from -1 to 0 for put options. For instance, a call option with a delta of 0.5 would increase by $0.50 if the underlying stock’s price increased by $1.
  • Gamma: Gamma, on the other hand, represents how fast delta changes as the stock price moves. It measures the rate of change of delta concerning changes in the underlying stock’s price. Essentially, it quantifies the option’s sensitivity to changes in delta. A higher gamma implies that delta changes more rapidly with fluctuations in the stock price.

Gamma Squeeze Real-World Examples

Gamma squeezes have occurred in various stocks, often driven by a combination of factors, including speculative trading, social media-driven momentum, and a high concentration of call options. Here are a few more real-world examples::

  1. GameStop (GME): The GameStop saga in early 2021 is perhaps the most famous example of a gamma squeeze. Retail traders, organized through online forums like Reddit’s WallStreetBets, piled into call options, driving up the stock price to astronomical levels. This led to substantial losses for short sellers and a frenzy of media attention.
  2. AMC Entertainment (AMC): Similar to GameStop, AMC Entertainment experienced a gamma squeeze in 2021 as retail traders rallied around the stock. Call option buying and delta hedging contributed to substantial price volatility.
  3. Tesla (TSLA): Tesla has been a subject of gamma squeezes on multiple occasions due to its high volatility and active options market. Rapid price movements in Tesla stock have been driven by call option activity and delta hedging by institutions.
  4. BlackBerry (BB): BlackBerry witnessed a gamma squeeze in early 2021. The stock’s price surged as retail traders and online communities rallied around it. This sudden momentum attracted attention and led to significant volatility.
  5. Nokia (NOK): Nokia experienced a gamma squeeze concurrent with the GameStop and AMC squeezes in early 2021. Retail traders and coordinated efforts contributed to notable price fluctuations.
  6. Kodak (KODK): Eastman Kodak’s stock price spiked dramatically in a short period in 2020. This event was attributed to news of the company receiving a government loan to produce pharmaceutical ingredients. Call option buying and delta hedging added to the rapid price increase.

How Gamma Squeeze Works?

Now that we have a grasp of gamma let’s explore how a gamma squeeze unfolds:

  1. Call Options Accumulation: A gamma squeeze typically begins with a surge in the purchase of call options on a specific stock or asset. Call options give the holder the right to buy the underlying asset at a predetermined price (strike price) before or on a specific expiration date.
  2. Delta Hedging: As traders buy call options, market makers and institutions who sold these options may engage in delta hedging to manage their risk. Delta hedging involves buying or selling shares of the underlying asset to offset the risk associated with the options they’ve sold.
  3. Feedback Loop: Here’s where the gamma squeeze takes shape. When market makers and institutions engage in delta hedging, they buy shares of the underlying asset in response to the increasing demand for call options. This surge in buying activity can drive up the stock’s price.
  4. Accelerated Demand: As the stock’s price rises, it can trigger more call options to be in-the-money (i.e., having intrinsic value) due to the increase in the stock price. This, in turn, prompts more buying of shares by market makers to hedge their positions.
  5. Reinforcing Cycle: The increasing stock price and accelerated buying of shares can create a reinforcing cycle, causing the stock to surge rapidly. This cycle can continue until the options expire or traders and market makers begin to unwind their positions.

Certainly, let’s dive deeper into the concept of a gamma squeeze, exploring its implications, real-world examples, and how traders can navigate this phenomenon.

4 Implications of a Gamma Squeeze

  1. Volatility Amplification: Gamma squeezes are notorious for their ability to amplify stock price volatility. As the buying pressure on call options accelerates, the corresponding delta hedging by market makers and institutions can lead to rapid and often unpredictable price swings. This heightened volatility can attract traders seeking short-term opportunities but can also deter more conservative investors.
  2. Short Squeeze Potential: Gamma squeezes can trigger short squeezes. Short sellers, who have bet on the stock’s decline, may be forced to cover their positions by buying shares. This surge in buying by short sellers looking to limit their losses adds further upward pressure on the stock price, potentially leading to a cascade effect of buying and further price increases.
  3. Market Disruption: A gamma squeeze can disrupt normal market dynamics. Traditional valuation metrics and technical analysis may temporarily lose their relevance as the forces driving the squeeze take over. This disruption can create trading opportunities for those who can navigate the chaos effectively but can also pose risks for traders unprepared for the rapid price fluctuations.
  4. Short-Term Nature: It’s important to understand that gamma squeezes are typically short-lived. The rapid price increase driven by the feedback loop of delta hedging and call option demand often reaches unsustainable levels. As traders take profits or unwind their positions, the stock price can experience sharp corrections, sometimes reverting to its fundamental value.

For traders and investors looking to navigate a gamma squeeze or capitalize on its opportunities, here are some key considerations:

  1. Volatility and Risk Management: Given the heightened volatility during a gamma squeeze, robust risk management is paramount. Setting stop-loss orders, defining risk tolerance, and sizing positions appropriately are essential steps to protect capital.
  2. Leveraging Options Strategies: Traders experienced in options may utilize strategies such as straddles and strangles to profit from increased volatility during a gamma squeeze. These strategies involve taking positions in both call and put options to capitalize on price fluctuations.
  3. Stay Informed: Stay up-to-date with news and market developments. Being aware of the factors driving the squeeze and any potential catalysts can help in making informed decisions.
  4. Technical Analysis: While traditional technical analysis may lose some relevance during a squeeze, it can still provide valuable insights. Identify key support and resistance levels to help guide entry and exit points.
  5. Short-Term Focus: Gamma squeezes are typically short-lived and characterized by rapid price movements. Traders looking to profit from these situations often have a short-term focus and are prepared to act swiftly.
  6. Know Your Strategy: Have a clear trading or investment strategy in mind. Are you looking for quick gains or considering a longer-term position? Define your objectives and stick to your plan.
  7. Technical Analysis Relevance: While traditional technical analysis may lose some relevance during a gamma squeeze, it can still provide valuable insights. Identifying key support and resistance levels, trendlines, and chart patterns can help guide entry and exit points.
  8. Continuous Learning: Like all aspects of trading and investing, mastering gamma squeezes requires continuous learning and adaptation. Stay informed about evolving market dynamics and emerging strategies.


A gamma squeeze is a complex phenomenon in the world of options and stock trading. It arises from the interplay between increasing demand for call options, delta hedging by market makers, and the resulting feedback loop of rising stock prices.

While gamma squeezes can create substantial trading opportunities and volatility, they are usually short-lived and characterized by rapid price corrections. Traders and investors should exercise caution and have a thorough understanding of options and market dynamics when navigating such situations, as they can present both risks and rewards.

Gamma Squeeze (FAQs)

1. What causes a gamma squeeze?

A gamma squeeze occurs when there is significant buying of call options on a particular stock or asset. Market makers and institutions who have sold these options may engage in delta hedging to manage their risk. This delta hedging involves buying shares of the underlying asset, which, in turn, can drive up the stock’s price. As more call options become in-the-money due to rising stock prices, the cycle of buying and delta hedging intensifies, leading to a gamma squeeze.

2. Are gamma squeezes illegal or unethical?

Gamma squeezes, like short squeezes, are not inherently illegal or unethical. They are market phenomena driven by supply and demand dynamics. However, they can attract regulatory scrutiny if they involve market manipulation or coordinated efforts to artificially inflate or deflate a stock’s price.

3. What’s the difference between a gamma squeeze and a short squeeze?

A gamma squeeze and a short squeeze are related but distinct phenomena. A gamma squeeze typically involves a surge in call option buying, which leads to delta hedging by market makers and institutions, causing the stock’s price to rise. In contrast, a short squeeze occurs when short sellers are forced to cover their positions by buying shares, causing a rapid price increase. While gamma squeezes often lead to short squeezes, they can also occur independently.

4. Are gamma squeezes predictable?

Gamma squeezes can be challenging to predict accurately. They often involve a combination of factors, including call option activity, delta hedging strategies, and market sentiment. Traders and investors should exercise caution and conduct thorough research before attempting to profit from or navigate a gamma squeeze.

5. How can investors protect themselves during a gamma squeeze?

Investors should employ robust risk management strategies, including setting stop-loss orders and defining their risk tolerance. It’s also essential to stay informed about news and market developments, as well as to have a clear exit strategy. Due to the rapid and unpredictable nature of gamma squeezes, investors should be prepared for substantial price swings.
