When coming across the constantly rising stock prices after long-term drops in the same, the sensitive short sellers guess the further scenario. As a result, they start buying back the stocks they already sold short. This, in turn, increases the buying pressure in the stock market, which boosts the prices of the assets and securities even more. However, traders’ sentiments and news also play a vital role in increasing stock prices. Whatever the reason, the instant and rapid increase in covering the short positionShort PositionA short position is a practice where the investors sell stocks that they don't own at the time of selling; the investors do so by borrowing the shares from some other investors to promise that the former will return the stocks to the latter on a later date.read more creates a huge imbalance in the market liquidity, which also adds to the factors influencing short squeezing.

The following charts demonstrate a couple of short squeezes concerning two different stocks — GameStop and Volkswagen on the daily timeframe.


As one can observe, the GameStop chart displays a bigger short squeeze when compared to Volkswagen stock. That said, both are similar from a fundamental standpoint. After all, short squeezes take place in the exact way; only the corrections differ.

With regard to the GameStop short squeeze, one may make the following observations:

  • Any individual who caught the trend prior to the run-up made the least risky investment.
  • Market participants pushed prices up because of the hype, leading to the formation of the first squeeze.
  • The first red or bearish candle suggested that all individuals who made decent gains were accumulating profits, and there was a possibility that market participants closed a few of the short positions.
  • The hype persisted, and the ones who were late to the party created another squeeze.
  • The second bearish candle represented the people who made decent gains for the second time and closed their positions, people who panicked, and market participants who closed their short positions.

Lastly, one could conclude that the mass hysteria and hype were fading away, and the people who purchased the top, hoping the price would rise further, were trapped.

Individuals can develop a comprehensive idea of this concept by looking at charts like these already published on TradingView.


The short squeeze examples below help us understand the concept more clearly:

Example #1

AMC Theaters recorded a loss worth $4.6 billion post-COVID-19 in 2020. However, the short squeeze phenomenon boosted its share prices to a great extent, giving traders a ray of hope. Recently, there have been speculations of another AMC short squeeze to happen soon despite a reduction in short shares to 89.1 million in August 2022, which is 7 million down from July, with almost 17% of stocks available to short again.

Example #2

Take the example of Volkswagen, where the short squeeze resulted in a significant jump in the stock price in October 2008. As a result, the stock price increased from €210 per share to over €1,000 per share in just two days, making it the most valuable company in the world for a brief period.

As a result, the short sellers expecting the stock price to fall were hammered and were forced to purchase the stock at €1,005 per share for short covering.

Gamma Squeeze vs Short Squeeze

A short squeeze situation arises when short sellers have to buy back their shares, given the constantly rising market prices. On the contrary, a gamma squeeze involves market makers betting on stocks when they observe multiple call options purchases for a particular stock by traders.

While the terms differ in how they work in the stock market, both contribute equally to significant spiking of the stock prices, causing enhanced buying pressure on the market.
