Top 5 Names on September 4, 2026
13. RNW — Squeeze Score 28.8
RNW tops the board despite a modest 2.1% short interest as a percentage of float and a 1.0-day days to cover. Its borrow fee is not available in today's data ("—" in the table), and its float utilization sits at 2.1%. What elevates the score is the threshold flag combined with a very short cover window — shorts can exit in a single session, which cuts both ways. The setup here is a low-SI, threshold-flagged small cap trading at $6.81. Any squeeze would be driven by threshold pressure persisting rather than by structural crowding; if short volume keeps exceeding 50% of total volume, the flag compounds the score.
14. RGC — Squeeze Score 28.5
RGC is the day's fee story: a 237.8% annualized borrow fee against only 1.8% SI of float and a 4.7-day cover window. This is the classic high-fee, tight-availability setup — shorts are paying an enormous carrying cost to stay positioned in a $6.71 stock, and the fee alone creates constant pressure to close. A squeeze here needs only persistence: if the borrow fee stays elevated or availability tightens further, holding the short becomes economically untenable regardless of price direction.
15. SVRA — Squeeze Score 28.2
SVRA pairs 29.6% SI of float with a 27.1-day days to cover — the longest cover window on today's board — plus a modest 2.6% borrow fee and positive 5-day momentum of 2.1%. This is a high-SI crowding setup in a $5.39 stock: nearly a third of the float is sold short and it would take almost a month of average volume to unwind. If a positive catalyst forces covering, the 27.1-day cover window is the mechanical amplifier.
16. EH — Squeeze Score 25.7
EH shows 15.2% SI of float, a 1.5% borrow fee, 16.3 days to cover, and the strongest positive momentum among today's top five at 4.0% over five days. The setup is a mid-SI name already moving against the shorts, with the stock at $4.69. If upward price action continues, the 16.3-day cover window means exits stay congested. Traders reviewing how similar setups played out historically often log them in a journal — see how Tapeboard compares as a TradeZella alternative for that workflow.
17. GRBK — Squeeze Score 25.1
GRBK carries 5.9% SI of float, a 0.4% borrow fee, and 9.0 days to cover at a $71.09 share price. This is a quieter, threshold-driven setup: the short-side pressure shows up in the FINRA flag rather than in an extreme fee or SI reading. A squeeze would require the threshold condition to persist long enough that the 9.0-day cover window starts to matter against any incremental buying.
Stocks Flagged on the FINRA Threshold List
The T column marks names on the FINRA threshold list — symbols where short volume exceeded 50% of total volume within the last seven trading days, indicating sustained heavy short pressure rather than a one-off session. Twenty-four of today's 25 names carry the flag; CYDY (score 23.3, 8.1% borrow fee, 17.1 days to cover) is the lone exception. Full scoring detail is in our methodology.
