How shorted is Aura Biosciences, Inc. right now?

9.91% of Aura Biosciences, Inc.'s (AURA) shares outstanding were reported short for settlement date 31 Jul 2026, per FINRA's consolidated short interest report.

What does this number include?

FINRA member firms must report their short positions in all US equities twice a month; FINRA consolidates them per security. We divide that official share count by the company's shares outstanding from its SEC filings. This is the regulatory figure, not a daily estimate.

Why does it only update twice a month?

US short interest is reported for settlement on the 15th and the last business day of each month, and FINRA publishes the consolidated figures about nine business days later. That cadence is set by regulation; no daily official figure exists.

Which funds are short?

US public short interest is aggregate-only: individual short sellers are not named. Only some EU markets publish named positions.
