6. OCGN — Squeeze Score 30.5
OCGN leads the board at a 30.5 score on 32.1% short interest, a 1.9% borrow fee, and 23.9 days to cover — the second-longest cover window on today's list. Shares are down 22.3% over five days at $1.05, and the name sits on the threshold list. This is the classic crowded-small-float setup: a deep short base, weak price action, and a cover window long enough that any positive catalyst forcing buy-ins would take weeks to clear at recent volume. If borrow availability tightens from the current 1.9%, the score has room to climb further.
7. SVRA — Squeeze Score 30.2
SVRA posts the longest days-to-cover figure on the board at 27.1, paired with 29.6% of float short and a 2.2% borrow fee. The stock has only slipped 2.6% over five days at $5.32, meaning shorts have not been rewarded recently despite the heavy positioning. The setup here is a slow-burn cover problem: nearly a month of average volume is needed to exit, so any sustained bid forces an extended unwind.
8. LU — Squeeze Score 29.6
LU scores 29.6 despite just 1.6% of float short, a 3.5-day cover window, and no borrow fee reading in today's data. Its rank is driven by threshold status and the other score components rather than raw short interest. This is a threshold-flagged momentum setup rather than a crowded short — the squeeze case depends on sustained heavy short-side volume continuing to show up in the daily file.
10. OPAL — Squeeze Score 25.9
OPAL carries 15.0% short interest, a 1.4% borrow fee, and 12.2 days to cover at $1.82, down 8.5% over five days. It is a mid-tier SI name with threshold confirmation — the kind of profile where a single positive catalyst can flip a grinding decline into a forced-cover rally because the short base is large relative to liquidity but not yet paying punitive borrow costs.
11. WB — Squeeze Score 25.9
WB rounds out the top five at 25.9, with 19.2% of float short, a 1.2% borrow fee, and 22.0 days to cover at $6.62. The long cover window is the standout metric: shorts are comfortable on cost but structurally slow to exit. Traders reviewing positioning in names like this often journal the setup in tools such as TradeZella to track how cover windows evolve before entry.
Highest Borrow Fees on September 10, 2026
The extreme outlier is RGC at a 216.9% annualized borrow fee against only 1.8% short interest — a hard-to-borrow profile where the cost of staying short is itself the squeeze mechanism. OPTT follows at 4.9% with 13.2% SI, then SVRA at 2.2% and OCGN at 1.9%. LU, MTH, and MGNX report no fee reading today.
Stocks Flagged on the FINRA Threshold List
Twenty-three of today's 25 names carry the T flag, including every top-five name. The T flag means the symbol shows sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file — more than 50% of recent volume was short-side. RNA (22.1% SI, 27.5 days to cover, down 26.4% over five days) is one of the few without the flag. See the full scoring methodology for how threshold status interacts with the score.
