Frequently asked questions
- What is short interest in CSIQ?
- Short interest is the total number of CSIQ shares currently sold short but not yet covered or closed out. FINRA publishes this data twice monthly.
- How is CSIQ short interest calculated?
- Short interest is aggregated from member firm reports to FINRA. Every U.S. broker-dealer must report aggregate short positions in each security as of the 15th and last trading day of each month.
- 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.
