Short interest for agen, ensc, inab, xlo, zvsa, glue, allr, apdn
7/25/2025 11:06am
**Key takeaway 🏹**
Among your eight biotech tickers, the *heaviest* short-crowding right now sits in Monte Rosa Therapeutics (GLUE 17 %) and Agenus (AGEN 12.7 %). The rest of the list carries only single-digit—or even sub-1 %—short exposure, so any “squeeze” narrative would need a fresh surge in bearish positioning or a sharp contraction in free float.
| Ticker | Latest reported short-interest shares | % of float (if available) | Reporting date* | Quick read |
|--------|--------------------------------------|---------------------------|-----------------|------------|
| GLUE | 7,840,000 | **17.0 %** | 31 Oct 2024 | High absolute and relative SI; 3.8 days to cover suggest shorts could feel heat on a big catalyst |
| AGEN | 2,241,148 | **12.70 %** | 25 Jul 2025 (FINRA tape) | Double-digit SI with 4.9 days to cover—watch clinical-data windows |
| ZVSA | 49,600 | 4.7 % | 31 Aug 2024 | Tiny float means even ~50 k shares = material %, but days-to-cover only 0.4 |
| ENSC | 689,400 | 6.3 % | 31 Aug 2024 | SI ballooned 3,885 % MoM last summer—bearish conviction has lingered |
| ALLR | 1,720,000 | 6.7 % | 30 Jun 2024 | SI swung sharply higher in Q2; float is microscopic, so moves can be violent |
| APDN | 2,140,000 | — (not disclosed) | 31 Aug 2024 | Raw shares elevated; % float not stated, but <3 days to cover keeps risk acute |
| INAB | 389,700 | 1.3 % | 15 Jun 2024 | Bears are minimal here; volume-driven spikes more likely than squeeze |
| XLO | 31,000 | 0.1 % | 31 Aug 2024 | Essentially no short crowding—squeeze dynamics unlikely |
\*FINRA/Nasdaq publish short-interest snapshots twice monthly, normally settling on the 15th and month-end; public release follows about eight trading days later.

### How to use this info 🧭
1. **Catalyst overlay**
• GLUE and AGEN enter conference season (SITC, ESMO) with elevated short stakes—positive data could force rapid covering.
• ZVSA trades OTC (float thin, liquidity sporadic); even a modest headline can whiplash price because shorts have <½-day of typical volume to unwind.
2. **Float math matters**
Absolute share counts can mislead—e.g., XLO’s 31 k shorts look tiny until you recall its float is >50 M shares, yielding a trivial 0.1 % SI. Focus on **% float and days-to-cover**, not just raw shares.
3. **Monitor the tape**
Track off-exchange (“DF”) prints and borrow-fee spikes; a sudden jump in either often precedes the official SI report by days.
4. **Protect yourself**
High-SI names can gap both ways. If you’re long:
• Use **stop-loss buffers** wider than usual to survive volatility.
• Size positions conservatively; borrow rates on GLUE, AGEN, ZVSA already run mid-single-digits (and can shoot >30 % overnight).
