Highest Borrow Fees on September 15, 2026
12. INDI — Squeeze Score 44.2
INDI leads the board at a 44.2 score with 30.3% of float short and 8.8 days to cover at a $3.15 share price. No borrow fee quote is available in today's data, but the float utilization of 30.3% combined with a -12.0% five-day slide describes a name where shorts are pressing aggressively. The setup is a classic threshold-flagged, high-SI small cap: if a positive catalyst forces covering, nearly nine sessions of average volume stand between shorts and the exit.
14. CRBP — Squeeze Score 43.6
CRBP scores 43.6 with 14.8% of float short, 3.7 days to cover, and a $6.88 price. The fee field is null, so the cost side of the trade is unquantified today. This is a moderate-SI threshold name rather than a high-fee trap — the squeeze case here depends on volume. At 3.7 days to cover, shorts can exit relatively quickly, so any squeeze would likely be sharp and brief rather than sustained.
15. PLAY — Squeeze Score 42.1
PLAY carries 32.5% of its float short — the third-highest SI on today's board — with 6.7 days to cover and a steep -22.4% five-day momentum reading at $6.95. No borrow fee is quoted. The setup is a crowded short riding a downtrend: shorts are deep in profit, which historically raises the odds of a violent unwind if the stock stabilizes, because nearly a third of the float must be repurchased to close the trade.
16. KRYS — Squeeze Score 41.9
KRYS is the fee standout among the leaders: a 27.8% annualized borrow fee against 14.3% SI and a heavy 15.3 days to cover at a $336.68 share price. This is the high-fee, slow-exit profile — shorts are paying meaningful carry every day to hold a position that takes over three weeks of average volume to unwind. If borrow availability tightens further or the fee climbs, the carry cost alone can force de-risking independent of price action. Traders tracking names like this should journal the fee drift alongside price; a structured review process (see our TradeZella comparison) makes that pattern visible over weeks.
17. PCRX — Squeeze Score 41.4
PCRX rounds out the top five at 41.4, with 21.7% of float short, a modest 1.9% borrow fee, and 17.0 days to cover at $24.08. The story here is duration, not cost: borrow is cheap, but the position is enormous relative to daily volume. With momentum at -6.9% over five days, shorts are winning the tape — but any sustained reversal would put a 17-session covering queue behind the bid.
Stocks Flagged on the FINRA Threshold List
Every name on today's board carries the T flag. The FINRA threshold marker means the symbol shows sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file — more than 50% of recent volume traded short-side within the last seven sessions. It does not predict direction; it confirms that shorting is the dominant flow. See /methodology/short-squeeze-score for how the flag feeds the composite score.
How the Squeeze Score Is Built
The Tapeboard short squeeze score blends five inputs: 35% SI%Float (FINRA), 25% Borrow Fee (IBKR), 20% Float Utilization, 15% Days to Cover, and 5% five-day momentum (Schwab), normalized to a 0–100 scale. Full weighting math and data-handling rules are documented at /methodology/short-squeeze-score.
