Top 5 Most Shorted Stocks on October 16, 2026
1. RXRX — Squeeze Score 90.2
RXRX holds the top spot with 30.8% of float short, so float utilization is also 30.8%. The borrow fee is 0.5%, days to cover is 4.9, and the stock trades at $4.16 after a 5-day move of -20.5%. It is a threshold-flagged, low-priced, high-SI setup. Covering pressure builds if a positive catalyst forces shorts to buy back into 4.9 days of volume.
2. NBIS — Squeeze Score 89.6
NBIS scores 89.6 on 19.5% short interest, a 0.4% fee and 2.4 days to cover. It trades at $188.41 after a 5-day move of -25.2%, and it is on the threshold list. This is a higher-priced name where the short side is lighter than most of the board, but the 2.4-day cover window is short. A sharp reversal would leave little time for shorts to exit in an orderly way.
3. FCEL — Squeeze Score 87.9
FCEL carries 32.1% of float short, the second-highest SI in the top five. The borrow fee is 0.3% and days to cover is 3.7. The price is $14.09 after a 5-day move of -27.9%, and the symbol is threshold-flagged. The setup is momentum-driven. If the selloff stalls, a crowded 32.1% short base has to be covered into a thinner float.
4. CIFR — Squeeze Score 87.5
CIFR scores 87.5 with 21.7% short interest, a 0.4% fee and only 1.8 days to cover, the lowest in the top five. It trades at $10.04 after a 5-day move of -33.6%, the steepest drop in the group. It is not on the threshold list. The mechanics favor a fast squeeze if the price turns, because 1.8 days of volume is all shorts need to cover.
5. NVAX — Squeeze Score 84.2
NVAX has the highest short interest in the top five at 32.3% of float, with a 0.4% fee and 5.3 days to cover. The price is $12.82 after a 5-day move of -11.7%, the mildest decline among the leaders, and it is threshold-flagged. A large short base with a 5.3-day cover window means any forced buying would be absorbed slowly, which can extend a move once it starts.
Highest Borrow Fees on October 16, 2026
Fees are low across most of the board. GRRR is the outlier at 14.5%, followed by TE at 1.3%, GRPN at 1.1% and INDI at 0.9%. GRPN also shows the highest short interest on the board at 65.6% of float and 11.7 days to cover.
Stocks Flagged on the FINRA Threshold List
The T flag means the symbol shows sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file, with more than 50% of recent volume on the short side within the last 7 trading days. Seventeen of today's 25 names carry it. See the full scoring breakdown for how the flag feeds the ranking.
How the Squeeze Score Is Built
The score runs from 0 to 100 and weights five inputs: 35% short interest as a percent of float (FINRA), 25% borrow fee, 20% float utilization, 15% days to cover, and 5% 5-day momentum. Short interest comes from FINRA reporting, and threshold status from SEC-regulated market data files. Read the methodology for the full formula.
