Short Squeeze

« Back to Glossary Index

A short squeeze occurs when a heavily shorted stock’s price rises sharply, forcing short sellers to buy back shares to cover their positions, which further drives up the stock price.

Understanding a Short Squeeze

A short squeeze typically happens in a market environment where there is rising investor confidence or positive news regarding a stock that is heavily shorted. This sudden uptick in price can trigger a cascading effect where short sellers, who have borrowed shares to sell with the expectation that the stock price will decline, must buy back shares at higher prices to limit their losses.

Key Components of a Short Squeeze

  • Short Selling: The practice of selling borrowed shares of a stock with the aim of buying them back at a lower price. If the stock price increases instead, short sellers face potential losses.
  • Short Interest: This indicates the number of shares that have been sold short but not yet covered or closed. A high short interest relative to the total outstanding shares can signal potential for a short squeeze.
  • Short Ratio: This metric compares the number of shares shorted to the company’s average daily trading volume, indicating how quickly those shorts could be covered.

Effects of a Short Squeeze

The effects of a short squeeze can be significant, leading to:

  • Increased Volatility: Prices may become extremely volatile as short sellers scramble to cover their positions.
  • Price Surge: The demand from short sellers to buy shares pushes the stock price even higher, which could attract new investors or traders.
  • Market Sentiment Shift: A short squeeze can change market perceptions of a stock and company fundamentals, which may attract bullish sentiment.

Real-World Example of a Short Squeeze

In January 2021, GameStop (GME) stock experienced a notable short squeeze. The stock had one of the highest short ratios on the market, with a significant percentage of its float sold short. When retail investors on platforms like Reddit began buying shares, the price skyrocketed from under $20 to an intraday high of $483. This forced many short sellers to cover their positions at significant losses, further fueling the upward price movement.

Understanding a short squeeze is crucial for traders, as it can present both risks and opportunities in the market. Both short sellers and potential investors need to watch stock price movements and trading volumes closely to understand and react effectively to market dynamics.
