Short Interest & FTDs
The Short Squeeze
When Shorts Get Squeezed
A short squeeze occurs when a heavily shorted stock rises sharply, forcing short sellers to buy back shares (cover), which pushes the price even higher.
Anatomy of a Squeeze
1. Stock is heavily shorted (high short %)
2. Positive catalyst or buying pressure
3. Price rises, shorts start losing
4. Margin calls force shorts to cover
5. Covering creates more buying pressure
6. Price spikes rapidly
7. Eventually exhausts and reverses
