Top 5 Short Squeeze Setups on May 11, 2026
The top five by Tapeboard squeeze score range from threshold-flagged momentum names to crowded-float biotech, with one classic high-cover, mid-fee outlier in the mix. Each name below pulls a different mechanic of a short squeeze.
2. GRPN — Squeeze Score 94.4
GRPN leads on raw float crowding: 59.4% short interest, 51.0% float utilization (the highest in the top 5), and 9.1 days to cover, all on +8.8% 5-day momentum at $16.95. The borrow fee is still modest at 0.9% annualized — this is a crowded-trade signal, not a hard-to-borrow one. If utilization climbs much further the locate desk has nowhere to source new shares without a fee re-rate, which is the mechanical lever that would force covering.
3. PLAY — Squeeze Score 84.9
PLAY carries the highest raw short interest on the board at 60.7% of float, but only 3.9 days to cover and -5.1% 5-day momentum at $10.09 — shorts are paying just 0.5% to hold the position and exiting is easy at current volume. The threshold flag is on, so the FINRA tape is sustaining the pressure. A positive earnings surprise or unexpected upside guidance is the classic catalyst that turns a 60% short-interest name into a forced-covering scenario.
4. CLSK — Squeeze Score 77.2
CLSK is the threshold-flagged momentum entry: 46.3% short interest, 34.2% float utilization, 4.3 days to cover, 0.3% borrow fee, and +11.5% 5-day momentum at $13.00. The setup is bitcoin-mining beta with a heavily-shorted float already rallying off a base. The mechanic here is straightforward — sustained spot crypto strength keeps mining-equity bids firm while shorts watch their entry basis erode on the tape.
5. INDI — Squeeze Score 77.2
INDI is the cover-time outlier: 30.6% short interest with 18.4 days to cover — the longest in the top 5 — plus a 3.3% borrow fee, +8.7% 5-day momentum, and the threshold flag, all at $4.72. Thin float plus light volume means a small absolute increase in buying interest forces a disproportionate response from shorts. A positive automotive-semis data point or a liquidity event is the kind of catalyst that starts the chain.
6. NTLA — Squeeze Score 76.9
NTLA is the highest-ranked non-threshold name on May 11, 2026: 36.8% short interest, 34.2% float utilization, 12.4 days to cover, 0.4% borrow fee, and +4.0% 5-day momentum at $14.46. Without the FINRA flag the pressure is structural rather than tape-confirmed — a binary clinical readout is the textbook covering catalyst for a gene-editing name carrying double-digit days to cover.
Highest Borrow Fees on May 11, 2026
RUM leads the board on stock-loan cost with a 24.7% annualized borrow fee, followed by BYND at 19.4%. Both are threshold-flagged. The next tier — IBRX at 4.4%, INDI at 3.3%, ABCL at 2.1%, XRX at 1.6%, and RXRX at 1.1% — covers the remaining genuinely expensive locates. Everywhere else on today's leaderboard the fee sits below 1%, meaning the squeeze setups are mostly crowded-float stories rather than hard-to-borrow ones.
Stocks Flagged on the FINRA Threshold List
A "T" in the right-hand column means the symbol shows up on the FINRA Consolidated NMS daily short-volume file with sustained heavy short-side activity — more than 50% of the stock's volume was executed on the short side within the last 7 trading days. It is a confirmation that real short-side pressure is hitting the tape, not just a stale bi-monthly short-interest snapshot. 20 of today's 25 candidates are flagged; the non-flagged exceptions are NTLA, BTDR, AI, TWST, and CURLF. See /methodology/short-squeeze-score for the full filter.
How Tapeboard's Squeeze Score Is Built
The 0-100 squeeze score blends five inputs: 35% short interest as a percent of float (Yahoo), 25% borrow fee (IBKR via iborrowdesk.com), 20% float utilization, 15% days to cover, and 5% 5-day price momentum (Schwab). Each input is normalized within the daily universe before weighting, so the score is relative to today's tape rather than an absolute threshold. Symbols with missing borrow or short-interest inputs (today: CURLF) score off the threshold and momentum components only. Full breakdown at /methodology/short-squeeze-score.
