What Drove Today's Rankings
The top 10 is built on expensive borrow: eight of the ten carry annualized fees of 25% or more, and every name except CIFR sits on the FINRA threshold list. The outlier is HUT at rank 6, the lowest-fee name in the top group at 25.0%, carried instead by a 16.2% SI% float reading and threshold status rather than loan cost. Because short interest and borrow fee together account for 60% of the composite weight, names like RXRX and LEU that score high on both factors cluster near the top even with mixed momentum.
Top 5 Names
1. FCEL — Squeeze Score 98.5/100
FCEL posts the highest composite on the board, anchored by 32.7% short interest against float and a 41.4% annualized borrow fee. Its 4.1 days to cover and +11.8% five-day momentum add to the score, while its threshold-list flag confirms short-side volume has dominated recent trading. The borrow fee was unchanged over the last five sessions.
2. TWST — Squeeze Score 97.6/100
TWST ranks second despite a -19.5% five-day price move, with 22.6% of float sold short and a 25.9% borrow fee. The stock carries a FINRA threshold flag and 4.2 days to cover. Its five-day fee change of -1.2 percentage points shows borrow costs easing slightly, but the composite still scores the loan as expensive relative to the universe.
3. RXRX — Squeeze Score 95.0/100
RXRX combines the third-highest short interest on the board at 34.8% of float with a 58.8% annualized borrow fee, the second-highest fee in the top 15. Days to cover stands at 6.5, the fee rose 1.3 percentage points over five sessions, and the name sits on the FINRA threshold list. Five-day momentum is +3.4%.
4. PRME — Squeeze Score 94.7/100
PRME is the strongest momentum name in the top five at +27.7% over five days, layered on 27.9% short interest and a 41.9% borrow fee. Its 7.6 days to cover is the longest in the top five. The five-day fee change is unavailable, so that component of the score reweighted across the remaining factors. The stock is on the threshold list.
5. SDGR — Squeeze Score 93.2/100
SDGR rounds out the top five with 19.4% short interest, a 26.1% borrow fee, and 3.4 days to cover. The borrow fee climbed 0.9 percentage points over the last five sessions even as the stock fell 12.1%. It holds a FINRA threshold flag, marking the fifth consecutive top-five name on the list.
Factor Breakdown: How the Score Is Built
Tapeboard's Short Squeeze Score (setup v6, since 2026-10-07) gates on short interest of at least 15% of float (FINRA settlement, point-in-time and split-safe), then ranks gated names 0-100 on 20-day volatility with the single largest daily move excluded (60%), 5-day float rotation (20%) and last-session relative volume (20%), each as a percentile among the gated names. A higher score means higher historical odds of a large move in either direction; it is not a directional call. Borrow fee, days to cover and the short-volume ratio are shown for context at zero weight. Data are sourced from FINRA, the SEC, and the NYSE and NASDAQ exchanges. Read the full methodology.

How does Tapeboard calculate its squeeze score?
The score gates on short interest of at least 15% of float (FINRA settlement, point-in-time), then ranks gated names 0-100 on 20-day volatility with the single largest daily move excluded (60%), 5-day float rotation (20%) and last-session relative volume (20%), each as a percentile among the gated names. Borrow fee, days to cover and the short-volume ratio are shown for context at zero weight. The full formula, the gate and the calibrated odds are published at the methodology page.
When does short-interest data update?
Short interest is published on the FINRA settlement schedule and lags roughly two weeks behind the trade date. Borrow fees update on a next-day basis, and short-volume threshold data is published daily.
