Frequently asked questions

What is short interest in RSLBF?

Short interest is the total number of RSLBF shares currently sold short but not yet covered or closed out. FINRA publishes this data twice monthly.

How is RSLBF 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.
