Top 5 Names on October 12, 2026
1. FCEL — Squeeze Score 95.7
FCEL leads the board with the day's highest score, combining 32.1% of float sold short, a 41.4% borrow fee, 3.8 days to cover, and a T flag. The stock is down 9.4% over five sessions to $18.03, so this is a threshold-flagged setup where shorts are pressing while already paying elevated carry. The mechanics: with a third of the float borrowed, any forced covering wave meets shallow borrow supply, and a positive catalyst would force shorts to buy into rising prices while paying 41.4% annualized to hold.
2. NVAX — Squeeze Score 90.3
NVAX posts the highest short interest on the top half of the board at 32.3% of float, with a 42.2% borrow fee and 5.6 days to cover at $12.75. Unlike most of the board, five-day momentum is positive at +0.8%, meaning shorts are underwater on the recent move while paying steep carry. If the price continues to grind higher, the 5.6-day covering window turns slow accumulation against shorts into a sustained bid.
3. TWST — Squeeze Score 88.4
TWST carries 19.1% short interest, a 25.0% borrow fee, and 3.2 days to cover, with the stock down 25.9% over five days to $159.78. This is a momentum-driven short pile-on: the fee is the lowest in the top five, so borrow is still available, but the T flag shows short-side volume dominating. A sharp reversal after a 25.9% five-day drop is the classic trigger, since late shorts entered near the lows and would cover quickly on any bounce.
4. RXRX — Squeeze Score 88.2
RXRX shows 30.8% of float short, a 52.3% borrow fee, and 5.2 days to cover, with the stock down 16.1% over five sessions to $4.36. This is a high-fee, high-SI small-cap setup: carry at 52.3% annualized bleeds short positions daily, and nearly a third of the float is already borrowed. If borrow availability tightens further or a catalyst forces covering, the combination of fee pressure and a 5.2-day exit window amplifies the move. Traders reviewing how past squeezes in this profile played out often journal entries and exits in a tool like TradeZella to study the covering pattern.
5. ASTS — Squeeze Score 87.7
ASTS rounds out the top five with 24.3% short interest, a 69.8% borrow fee, and 4.5 days to cover at $50.97, down 11.9% over five days. The 69.8% fee is the second-highest in the top five, so this is a tight-borrow setup where holding short costs roughly 0.19% per day in carry alone. If borrow rates climb toward triple digits or recall risk rises, shorts face a choice between paying up and covering into strength.
Stocks Flagged on the FINRA Threshold List
The T column marks symbols on the FINRA threshold list, meaning more than 50% of recent volume on the FINRA Consolidated NMS daily short-volume file was short-side, a sign of sustained heavy short pressure rather than a one-day spike. Today 21 of 25 names carry the flag. The full scoring breakdown is at /methodology/short-squeeze-score.
How the Squeeze Score Is Built
The score weights five inputs: 35% SI%Float (FINRA), 25% Borrow Fee, 20% float utilization, 15% Days to Cover, and 5% 5-day momentum. Data is sourced from FINRA and SEC filings. See /methodology/short-squeeze-score for the full methodology.
