Top Short-Squeeze Candidates Today: September 10, 2026 — 7-Factor Leaderboard
OCGN leads Tapeboard's September 10, 2026 squeeze leaderboard with a 30.5 composite score, as elevated short interest and long days-to-cover — not extreme borrow fees — drive today's top rankings.
TL;DR: As of market close on September 10, 2026, OCGN leads Tapeboard's 7-factor squeeze leaderboard with a score of 30.5/100, driven by its 32.1% short interest and a 1.9% annualized borrow fee.
Tapeboard's daily squeeze scan ranked 25 stocks by composite score on September 10, 2026, combining seven factors: short interest as a percentage of float, annualized borrow fee, float utilization, the FINRA Consolidated NMS short-volume ratio, days to cover, five-day price momentum, and week-over-week borrow-fee change — each z-scored against a live ~500-stock universe. Today's dominant pattern is high short interest paired with extended days-to-cover rather than extreme borrow costs: the top two names carry SI above 29% of float and days-to-cover above 23, while nearly every name in the top 15 sits on the FINRA threshold list. This is a composite short squeeze ranking — not a raw most-shorted list.

What Drove Today's Rankings
The dominant signal across the top 10 is the combination of double-digit short interest and multi-week days-to-cover: OCGN, SVRA, WB, and RNA all pair SI above 19% of float with 22+ days to cover. The outlier is LU at rank 3, which scores 29.6 despite just 1.6% SI and 3.5 days to cover, with its score reweighted across the remaining factors where borrow fee and momentum data are null. Under the model's weights — 35% SI% float, 25% borrow fee, 20% float utilization — names like OCGN and SVRA earn their top slots primarily on the short-interest and utilization legs rather than fee stress.
Top 5 Names
1. OCGN — Squeeze Score 30.5/100
OCGN's primary driver is short interest at 32.1% of float, the second-highest SI reading on today's board, combined with 23.9 days to cover. Its 1.9% annualized borrow fee is moderate, but the fee has eased 0.29 percentage points over five days. The stock is on the FINRA short-volume threshold list, and its 5-day momentum of -22.3% is the second-weakest in the top 10.
2. SVRA — Squeeze Score 30.2/100
SVRA pairs 29.6% short interest with the highest borrow fee in the top five at 2.2% annualized. Days-to-cover of 27.1 is the second-longest on the board, and the borrow fee has fallen 0.49 percentage points over five days. SVRA carries the FINRA threshold flag, with 5-day momentum of -2.6%.
3. LU — Squeeze Score 29.6/100
LU's score of 29.6 is built without borrow-fee or momentum inputs — both are null, so the score is reweighted across the remaining factors. Its reported short interest is just 1.6% of float with 3.5 days to cover, meaning its rank rests on the short-volume and utilization components. LU is on the FINRA threshold list.
4. OPAL — Squeeze Score 25.9/100
OPAL combines 15.0% short interest with 12.2 days to cover and a 1.4% annualized borrow fee. Five-day momentum of -8.5% and a 0.06 percentage-point fee decline over five days round out its factor profile. OPAL holds the FINRA threshold flag and is the only Energy-sector name in today's top five.
5. WB — Squeeze Score 25.9/100
WB's primary driver is 19.2% short interest against 22.0 days to cover, one of the longest cover windows in the top 15. Its 1.2% borrow fee is the third-highest in the top five, though the fee slipped 0.02 percentage points over five days. WB is on the FINRA threshold list with 5-day momentum of -2.4%.
Factor Breakdown: How the Score Is Built
The composite weights five published components: 35% SI% of float (FINRA), 25% borrow fee, 20% float utilization, 15% days to cover, and 5% five-day momentum, with each factor z-scored against the ~500-stock universe and missing inputs reweighted across the remainder. Full details are in the methodology.
Frequently Asked Questions
What are the top short-squeeze candidates today?
The top three by composite score on September 10, 2026 are OCGN (30.5, 32.1% SI, 1.9% borrow fee), SVRA (30.2, 29.6% SI, 2.2% fee), and LU (29.6, 1.6% SI, fee data unavailable). All three carry the FINRA short-volume threshold flag.
How does Tapeboard calculate its squeeze score?
Each of seven factors — SI% of float, borrow fee, float utilization, FINRA short-volume ratio, days to cover, 5-day momentum, and 5-day fee change — is z-scored against a ~500-stock universe and combined using published weights (35% SI, 25% fee, 20% utilization, 15% days-to-cover, 5% momentum). Null inputs are reweighted across the remaining factors.
When does short-interest data update?
Short interest lags roughly two weeks because it publishes on the FINRA settlement schedule. Borrow fees update next-day from stock-loan availability, so the fee leg of the score is always fresher than the SI leg.
