Short Squeeze

A short squeeze refers to a rapid increase in the price of a stock that occurs primarily due to technical factors in the market rather than underlying fundamentals. It typically happens when a stock with a large amount of short interest begins to increase in price, forcing short sellers to close their positions by buying the stock. This additional buying pressure can lead to an accelerated surge in the stock’s price.

Here’s a step-by-step breakdown of how a short squeeze happens:

  • Initial Short Selling: Traders and investors sell a stock short because they believe its price will decrease. Short selling involves borrowing shares to sell them at the current price with the hope of buying them back later at a lower price to pocket the difference.
  • Catalyst for Increase: Something prompts the stock price to start rising. It could be positive news about the company, better-than-expected earnings results, a favorable macroeconomic indicator, or even just rumors.
  • Short Sellers Begin to Buy: As the price rises, short sellers may start incurring losses. Those who want to limit their losses will decide to close out their short positions. To do this, they have to buy the stock in the market to return the borrowed shares.
  • Snowball Effect: The additional buying from short sellers closing their positions can cause the stock price to rise even further. This can force more short sellers to buy the stock to close their positions, creating a snowball effect.
  • Peak and Decline: Eventually, the buying pressure from short sellers subsides, and other factors (like the stock’s underlying fundamentals) may come into play. The stock price might stabilize or even decline if the rapid price increase was largely due to the short squeeze and not supported by the company’s intrinsic value.

Example of a Short Squeeze

Let’s delve into a fictional scenario to illustrate a short squeeze:

Scenario: The Rise and Squeeze of StarNet Inc.


StarNet Inc. is a tech company that promised a revolutionary internet technology but had faced several setbacks, leading many to doubt its prospects. Given these doubts, many traders decided to short the stock, anticipating further price declines. Approximately 5 million shares were shorted out of the 20 million available for trading (a 25% short interest).

The Unexpected News:

One Monday morning, StarNet announces a breakthrough in its technology and a major contract with a leading tech company. The stock price, which had been languishing at $10, starts to rise rapidly on this unexpected positive news.

The Squeeze Begins:

  • By Tuesday, the stock price reaches $15, a 50% increase. Some short sellers decide to cut their losses and buy back shares to cover their short positions. Their buying adds more upward pressure on the stock price.
  • On Wednesday, the stock opens at $20. Panic starts to set in among the short-selling community. The more the price rises, the larger their potential losses become.
  • Financial news outlets pick up the story, discussing the potential of a massive short squeeze for StarNet. This draws even more attention and buying interest from regular investors and traders looking to capitalize on the momentum.
  • By Friday, the stock price has skyrocketed to $40, primarily driven by short sellers scrambling to buy shares and cover their positions. Those who entered their short positions at $10 are now facing a 300% loss.

After the Squeeze:

  • With most of the short positions covered and the buying frenzy calming down, the stock begins to stabilize. Over the next week, it settles around $30 as analysts and investors reassess StarNet’s actual value in light of the recent news.
  • While the company’s prospects have indeed improved, many believe the rapid run-up to $40 was exaggerated due to the short squeeze.

This scenario highlights the dangers of short selling, especially in stocks with high short interest. It also underscores the potential volatility that can arise when unexpected positive news challenges the prevailing sentiment around a heavily shorted stock.
