1. FCEL — Squeeze Score 96.6

FuelCell Energy leads the October 22, 2026 leaderboard with a squeeze score of 96.6. Short interest sits at 33.2% of float, the borrow fee is 25.2%, and days to cover are 3.3. The stock is flagged on the FINRA threshold list, meaning more than 50% of recent volume was short-side. A catalyst that forces covering could pressure borrow availability and drive the squeeze score higher.

2. NVAX — Squeeze Score 92.2

NVAX ranks second with a squeeze score of 92.2. Short interest is 32.3% of float, the borrow fee is 40.8%, and days to cover are 5.1. The name is threshold-flagged, indicating sustained heavy short pressure. If borrow availability tightens further, short covering could accelerate across the 32.3% of float held short.

3. WULF — Squeeze Score 90.3

WULF posts a squeeze score of 90.3 with short interest at 31.2% of float and a borrow fee of 41.4%. Days to cover stand at 3.2, and the symbol carries the threshold flag. This is a high-fee tight-float setup where any positive catalyst could force shorts to cover quickly given the elevated loan cost.

4. IREN — Squeeze Score 89.5

IREN ranks fourth at 89.5 with short interest of 23.6% of float and a borrow fee of 41.7%. Days to cover are just 1.6, the lowest among the top five. The name is not threshold-flagged. The high borrow fee relative to low days to cover suggests expensive stock loan without the same threshold-list pressure seen at the top of the board.

5. NBIS — Squeeze Score 87.8

NBIS scores 87.8 with short interest at 19.5% of float and a borrow fee of 41.4%. Days to cover are 2.2, and the symbol is not threshold-flagged. Five-day momentum is negative at roughly 15.5%. The setup pairs elevated borrow costs with moderate short interest and no FINRA threshold flag.

What the T Flag Means

The T column marks symbols on the FINRA threshold list, which identifies stocks where short volume exceeded 50% of total volume over a sustained window. For full details on how the flag factors into scoring, see the methodology at /methodology/short-squeeze-score.

How the Score Is Built

The Tapeboard squeeze score combines five inputs: 35% short interest as a fraction of float from FINRA, 25% borrow fee, 20% float utilization, 15% days to cover, and 5% 5-day momentum, with data attributed to FINRA and SEC. Reviewing trades and journaling setups can help traders track how these factors evolve across sessions. Read the full scoring breakdown at /methodology/short-squeeze-score.
