Top 5 Short Squeeze Setups on June 18, 2026
5. GRPN — Squeeze Score 51.1
GRPN is the most heavily positioned name on today's board: 64.6% of float is held short, days to cover sits at 6.3, and float utilization matches at 64.6% — leaving almost no unencumbered shares in the lending pool. The borrow fee of 1.2% is not yet punishing, meaning the cost-of-carry pressure is modest, but the extreme float utilization leaves the position structurally fragile. The 5-day price momentum is −4.0%, currently giving shorts confirmation. If that trend reverses, the 6.3 days-to-cover means shorts would need more than a week at normal volume to fully unwind, concentrating covering demand into a compressed window against a float that is already almost entirely encumbered at $16.16 per share.
8. ELF — Squeeze Score 42.2
ELF carries 48.9% of float short at $65.18 with only 2.0 days to cover. The low days-to-cover figure means short positions are relatively liquid — exits are possible in a single session under normal volume — but nearly half of all lendable float is already absorbed by short sellers. The 5-day momentum of +5.8% is already working against the position; if buying pressure compounds, the combination of 48.9% float short and a high per-share price makes the notional covering demand material. Tightening borrow availability or a single session of elevated volume could push the fee above its current 0.4% floor and accelerate exits.
9. CHWY — Squeeze Score 41.9
CHWY has 51.3% of float short at $18.22 with 2.8 days to cover. A majority of the lendable float is on the short side, yet the 0.4% borrow fee indicates no current scarcity premium for shares to borrow. The 5-day momentum of −3.0% is favorable for shorts at the moment, but the float utilization of 51.3% means any sustained shift in direction puts more than half the float's short positions under pressure simultaneously. If a positive catalyst draws buyers, the 2.8 days-to-cover figure means covering would need to happen quickly and could absorb available liquidity at current volume levels.
11. NTLA — Squeeze Score 36
NTLA presents the most mechanically charged setup in the top 5: 36.2% of float short, 9.2 days to cover, priced at $15.58, with a 5-day price momentum of +26.9%. That upward move means shorts are already facing mark-to-market losses, and the 9.2 days-to-cover means orderly exit at current volume takes nearly two full trading weeks. The 0.4% borrow fee has not yet reflected tightening, but sustained price appreciation often precedes availability constraints in the lending market. If the upward momentum continues and borrow availability begins to contract, the fee could rise sharply, adding cost-of-carry pressure to an already adverse position.
12. RH — Squeeze Score 35.8
RH carries 41.1% of float short at $147.99 with 6.0 days to cover and a borrow fee of 0.3%. At that share price, the notional value of covering pressure per point of upside is elevated relative to lower-priced names on this list — each covering buyer absorbs a meaningful dollar amount of available supply. The 5-day momentum of −7.0% is currently running in favor of shorts. But a 41.1% float short position with 6.0 days to cover is structurally exposed: if the trend reverses, the covering timeline stretches into the following trading week, and institutional positioning at $147.99 per share tends to produce larger discrete order sizes that can move bids rapidly.
Stocks Flagged on the FINRA Threshold List
The "T" column marks names where short volume has sustained above 50% of total volume on the FINRA Consolidated NMS daily short-volume file, qualifying them for the FINRA threshold list. Twenty-four of today's 25 names carry that flag — BTDR, with a score of 33.0 and 41.5% of float short, is the sole exception. Threshold status signals persistent, concentrated short-side order flow beyond single-session positioning. Full scoring methodology is at /methodology/short-squeeze-score.
How the Tapeboard Squeeze Score Is Built
The score weights five inputs: 35% short interest as a percent of float (FINRA), 25% borrow fee (IBKR stock-loan availability data), 20% float utilization (FINRA), 15% days to cover (FINRA/Schwab), and 5% five-day price momentum (Schwab). Disclosure data is drawn from SEC filings. Full weighting tables and update cadence are at /methodology/short-squeeze-score.
