Frequently asked questions
- What is short interest in MP?

- How is MP short interest calculated?

- What does a high short interest mean?
- Higher short interest can indicate bearish sentiment, but it also raises the potential for a short squeeze if positive news forces short sellers to cover their positions simultaneously. Compare short interest to float (short percent of float) for context.
