5. CELU — Squeeze Score 39.2
CELU leads the board at 39.2 despite missing short interest and borrow fee prints in today's data — its score is carried by 10.24 days to cover, a thin 2.1% float utilization, and a 13.2% gain over the last five sessions at a $1.90 price. This is a momentum-against-shorts setup: the stock is already rising into a position base that needs nearly ten sessions of average volume to exit. If the upward drift continues and borrow availability tightens, shorts are forced to chase a rising offer to close.
6. RGC — Squeeze Score 37.9
RGC is the fee story of the day. The borrow fee on RGC is 258.9% annualized — by far the highest on the August 27 board — against a modest 1.6% SI % float and 4.05 days to cover at a $5.50 price. This is the classic hard-to-borrow setup: reported short interest looks small precisely because locating shares is expensive and scarce. Shorts paying triple-digit annualized fees have a constant carrying-cost bleed, so any sustained price strength forces an economic decision to cover regardless of conviction.
7. BX — Squeeze Score 37.7
BX scores 37.7 with 2.9% of float short, 4.22 days to cover, and a $143.66 price — no borrow fee print in today's data. BX is a large-cap threshold-list case: it sits on the FINRA threshold flag, meaning short-side volume has dominated recent trading even though the absolute SI is low. Squeezes in names this size are mechanical rather than explosive — if short volume stays above half of total volume, sustained buy flow grinds against a crowded short book.
8. KOD — Squeeze Score 37.0
KOD combines 26.0% SI % float with a heavy 20.61 days to cover at $40.30, while the borrow fee remains cheap at 0.3%. This is a high-SI, high-days-to-cover setup where the crowding is the risk, not the carry cost. With five-day momentum at -1.8%, shorts are currently winning; a squeeze here requires a positive catalyst that forces a fraction of that 26% short base to exit into a tape that needs over 20 sessions to absorb it.
9. URGN — Squeeze Score 36.0
URGN posts 10.6% SI % float, 6.64 days to cover, and a $45.50 price, with no borrow fee reported today and the FINRA threshold flag active. This is a threshold-flagged mid-SI setup: short volume has dominated recent sessions, and the float utilization matches SI at 10.6%, confirming the short base is real and measurable. If a positive catalyst hits while short pressure stays above the threshold, covering demand meets limited liquidity.
Stocks Flagged on the FINRA Threshold List
The T column marks names on the FINRA threshold list — symbols where short-side volume has exceeded 50% of total volume on the FINRA Consolidated NMS daily short-volume file within the last seven trading days, indicating sustained heavy short pressure rather than a one-day spike. Twenty-one of today's 25 names carry the flag, including every name from RGC at 37.9 through BIIB at 30.5. The full flag definition and scoring inputs are documented in our methodology.
How the Squeeze Score Is Built
The Tapeboard squeeze score weights five inputs: 35% SI % float (FINRA), 25% borrow fee (IBKR stock-loan availability), 20% float utilization, 15% days to cover, and 5% five-day price momentum (Schwab). Scores run 0–100, with higher values indicating greater short squeeze potential. Full formulas and data windows are at /methodology/short-squeeze-score.
