Atreca, Inc. was delisted on Mar 20, 2024; its insiders filed their last Form 4 on Apr 17, 2024; 43 institutions reported holding it in 13F filings for Q4 2023, worth $1.24M in total; no superinvestor held 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.

Fails-to-deliver
Shares that weren't delivered by the settlement date, from the SEC, for the last 30 dates with fails. The price is the previous day's closing price published by the SEC.
The SEC has reported no fails-to-deliver for BCEL.
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.
FINRA has reported no daily short volume for BCEL in the last two years.
ATS (dark pool) volume
Weekly volume on alternative trading systems (ATS) and other off-exchange (OTC) venues, from FINRA, for the last 12 weeks. ATS share is ATS volume ÷ (ATS + OTC volume), not a share of all trading.
