Top 5 Squeeze Candidates on May 12, 2026
1. ENVB — Squeeze Score 100
ENVB holds the perfect 100 score with a 471.4% annualized borrow fee, 45.7% SI/float, and 47.9% float utilization at $2.60. The days to cover figure — 0.09 — tells a different story than the fee: shorts can theoretically exit in a fraction of a session at recent volume, so this is a cost-of-carry setup, not a volume-crunch setup. 5-day momentum is -27.6%, meaning the trade is currently working for the short side. The squeeze mechanic here is purely economic: if borrow availability tightens further or the slide reverses, the fee alone makes any held short position cripplingly expensive to maintain.
2. GRPN — Squeeze Score 82.1
GRPN is the highest pure short-interest name on the board at 59.2% SI/float, with 51.8% float utilization and 6.65 days to cover at $17.49. Borrow is only 0.9%, so this is not a fee squeeze — it's a crowding squeeze. 5-day momentum is +15.5%, meaning shorts are already taking heat. If price continues higher and utilization presses past 60%, the mechanical pressure to cover compounds quickly given how concentrated the short side has become and how little room remains in the lendable pool.
4. CLSK — Squeeze Score 67.7
CLSK shows 49.5% SI/float and 36.4% float utilization at $13.40, with 4.48 days to cover and just a 0.3% borrow fee. The borrow is cheap, but the short interest figure is the second-highest in today's top 25. A bitcoin-correlated name on the threshold list with this much crowding and a sub-5 days-to-cover figure is the textbook fast-unwind configuration: any sharp upmove in correlated crypto assets forces shorts to cover into thin float in a hurry.
5. RXRX — Squeeze Score 64.4
RXRX carries 34.2% SI/float, 33.4% float utilization, and 15.03 days to cover at $3.14 — among the longest covering windows in the top 25. The 1.2% borrow fee is modest and 5-day momentum is -6.5%. The setup is the structural inverse of ENVB: low fee, low price, but a deeply crowded short with a slow exit door. If a positive catalyst forces covering, the high days-to-cover figure means shorts cannot exit quickly — and that mismatch between covering demand and available daily volume is what fuels squeezes when they happen.
6. NVAX — Squeeze Score 64.2
NVAX posts 30.3% SI/float, 35.0% float utilization, 15.57 days to cover, and a 0.4% borrow fee at $9.65. 5-day momentum is +18.8% — the strongest move in the top 10. Days to cover above 15 paired with a positive momentum trend is the configuration to watch most closely: shorts face an extended covering runway against rising prices, and the threshold flag confirms the short side has been consistently aggressive across the most recent week of NMS data.
Stocks Flagged on the FINRA Threshold List
The "T" column flags symbols on the FINRA Consolidated NMS daily short-volume threshold list — meaning more than 50% of the symbol's reported tape volume has printed on the short side across the past seven trading sessions. It measures sustained short pressure, not a one-day spike. Twenty-one of today's top 25 carry the flag, which is why this leaderboard reads as broad rather than concentrated.

How the Tapeboard Squeeze Score Is Built
The 0–100 squeeze score is a weighted blend: 35% SI%Float (Yahoo Finance), 25% borrow fee (IBKR via iborrowdesk.com), 20% float utilization, 15% days to cover, and 5% 5-day price momentum (Schwab). Names with both high short interest and a high borrow fee concentrate at the top of the table; names with high days to cover but cheap borrow tend to sit in the middle. See /methodology/short-squeeze-score for the full formula and per-source data freshness.
Tomorrow's refreshed list, recomputed against end-of-day data, will be published at the live leaderboard.
