Short Interest

What Is Short Interest?

Short interest is the number of shares sold short but not yet covered. It reflects how many market participants are betting a stock will fall.

Why It Matters

High short interest can signal bearish sentiment, but it can also set up a short squeeze if positive news forces traders to buy back shares quickly.

How to Use It

• Check short interest alongside volume and trend.
• Compare the short interest ratio, or days to cover.
• Do not treat it as a buy or sell signal by itself.

Examples

Heavily shorted names like GME and AMC have shown how fast sentiment can reverse. More established names can also see elevated short interest during earnings stress or sector weakness.

Key Takeaways

• Short interest measures bearish positioning.
• High short interest can lead to squeezes.
• Use it as one part of a broader analysis.
