How to read a month of short interest

A short position is a count of borrowed shares sold and not yet bought back, reported by brokers twice a month. A large count can be a hedge against a convertible bond, an index arbitrage leg or a pair trade, so the tables show size and change, never intent. Days to cover says how many average sessions of volume the position equals; it is a ratio, not a forecast of a squeeze.

The change tables compare share counts, so a corporate action moves them as surely as trading does. A reverse split shrinks a position without anyone buying shares back, and a spin-off or merger can add one overnight. Before reading a large change as a decision by short sellers, check the company’s filings for the same weeks.

Names and venues come from the FINRA rows themselves. Rows stored before August 2026 carry neither, so they are read from the newest stored row for the same symbol; where no such row exists the table says the venue is not recorded instead of guessing it.

FINRA is the owner and source of this short interest and short sale volume data. Free on every plan; not for redistribution.
