Frequently asked questions
- How shorted was Barinthus Biotherapeutics plc?
- Barinthus Biotherapeutics plc left the US market in 2026. Its final reported figure was 0.11% of shares outstanding for settlement date 31 Jul 2026, per FINRA's consolidated short interest report; this page preserves its full history.
- 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.
- Is this BRNS's short float?
- No. This is short interest as a percentage of shares outstanding, the count in the company's SEC filings. "Short float" divides the same FINRA short count by the public float, which excludes closely held shares, so it comes out higher for the same company. We publish no float estimates: the float is not a regulatory figure.
- What is BRNS's days to cover?
- 1.82 days for settlement date 31 Jul 2026: FINRA's own short interest ratio, the reported shares short divided by average daily trading volume. It is published in the same FINRA file and shown verbatim; we hold no volume data ourselves.
- Which funds are short?
- US public short interest is aggregate-only: individual short sellers are not named. Only some EU markets publish named positions.
