short interest

The total number of shares of a company that have been sold short but not yet covered, expressed as a number or percentage of float.

Example

GameStop's 140% short interest — more shares shorted than existed in the float — made it uniquely vulnerable to a short squeeze.

Memory Tip

SHORT INTEREST = how many shares are SHORTED. High short interest = potential for a short squeeze.

Why It Matters

Short interest matters because it can signal potential price volatility and market sentiment about a company. A high short interest level may indicate that many investors believe the stock price will fall, but it can also create a situation where shares become scarce and prices may spike unexpectedly.

Common Misconception

Many people assume that high short interest always means a stock is overvalued and will definitely decline in price. In reality, short interest simply reflects bearish sentiment and does not guarantee price movement in any direction.

In Practice

If a company has 50 million shares outstanding and 10 million shares have been sold short but not covered, the short interest would be 20 percent of the float. When positive news about the company emerges, those short sellers may rush to buy shares to cover their positions, potentially driving the price up rapidly and creating what is known as a short squeeze.

Etymology

SHORT (sold without ownership) INTEREST (total outstanding position). Total INTEREST (exposure) in SHORT positions.
