Top 5 Most Shorted Stocks on September 29, 2026
1. KOD — Squeeze Score 99.7
KOD carries 27.2% short interest, a 0.4% borrow fee and 3.5 days to cover at a price of $90.88. It is a threshold-flagged momentum setup: the stock is up 169.6% over five days while shorts remain heavily positioned. Covering pressure builds when a rising price forces margin-driven buybacks, and 3.5 days to cover means exits take multiple sessions of normal volume to absorb.
2. VKTX — Squeeze Score 97.2
VKTX shows 19.9% short interest, a 0.6% borrow fee, the highest in the top five, and 3.1 days to cover at $32.04. It is on the threshold list despite a 22.1% five-day decline, so shorts are pressing a stock already moving in their favor. A positive catalyst would force covering into a position that is sitting on gains, and the borrow fee would be the first signal of tightening supply.
3. SMR — Squeeze Score 93.5
SMR has 22.4% short interest, a 0.4% borrow fee and 2.0 days to cover at $7.83, down 12.7% over five days. It is a threshold-flagged setup with a short cover window. At 2.0 days, a reversal could unwind positioning quickly, which makes the setup fast rather than durable.
4. IOVA — Squeeze Score 93.1
IOVA posts 22.5% short interest, a 0.3% borrow fee and 5.0 days to cover at $14.45, up 35.8% over five days. It is not on the threshold list, so the score rests on positioning and cover time rather than sustained daily short volume. With 5.0 days to cover, a sustained bid would leave shorts competing for exits across several sessions.
5. FCEL — Squeeze Score 92.1
FCEL has 32.7% short interest, the highest in the top five, and 3.7 days to cover at $17.05, down 5.4% over five days. No borrow fee is available in today's data, and the name is not threshold-flagged. This is a high-short-interest setup where the size of the short base, not the cost of carrying it, drives the score. Squeeze mechanics would depend on a catalyst forcing covering into that base.
Highest Borrow Fees on September 29, 2026
Borrow costs are low across most of the board. TE has the highest fee at 4.3% with 34.0% short interest and 3.4 days to cover. CHPT follows at 4.1% with 21.6% short interest and only 1.3 days to cover, the shortest window on the list. RXRX has the longest window at 9.0 days to cover, with a 0.5% fee and 34.8% short interest. FCEL, BTBT, SDGR, TWST and GENI have no fee data today, shown as "—" in the table.
Stocks Flagged on the FINRA Threshold List
The T flag marks symbols with sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file: more than 50% of recent volume was short-side within the last seven trading days. Today, 18 of 25 names carry it, including KOD at 99.7 and CHPT at 88.9. IOVA at 93.1 and FCEL at 92.1 rank high without it. The full breakdown is in the methodology.
How the Squeeze Score Is Built
The score is a 0-100 composite. Short interest as a percent of float (FINRA) carries 35%, borrow fee (IBKR) 25%, float utilization 20%, days to cover 15% and five-day momentum (Schwab) 5%. Higher scores mean more squeeze potential. See the scoring methodology for the full formula.
