Arch Resources, Inc. was delisted on Jan 14, 2025; its insiders filed their last Form 4 on Jan 14, 2025; 223 institutions reported holding it in 13F filings for Q4 2024, worth $2.51B in total; Aquamarine was the only superinvestor holding it.
Four kinds of short-selling data, each measuring something different:
- Short interest: shares sold short and not yet bought back, as of a settlement date. FINRA publishes it twice a month, about eight business days after the settlement date.
- Daily short volume: shares sold short each day in off-exchange trades reported to FINRA. It counts trades, not open positions, and is published the next day.
- Fails-to-deliver: shares not delivered by the settlement date. The SEC publishes them twice a month, about two weeks late.
- ATS (dark pool) volume: weekly volume on alternative trading systems and other off-exchange venues. FINRA publishes it two to four weeks after the week.

Daily short volume
Off-exchange short-sale volume, not short interest: shares sold short each day in trades reported to FINRA, for the last 30 trading days.
The short volume ratio isn't a sentiment gauge: market makers sell short to fill buy orders and to hedge, so short sales are usually about half of off-exchange volume.
