Most Shorted Stocks Today: June 8, 2026 — Top 25 Squeeze Candidates
On June 8, 2026, the most shorted stocks are led by OST (squeeze score 100, 49.2% borrow fee) and CETX (77.1% short interest of float), in a leaderboard dominated by small-cap, high-fee names on the FINRA threshold list.
The most shorted stocks on June 8, 2026 are topped by OST, which carries a perfect Tapeboard squeeze score of 100 — driven not by heavy short interest (just 3.5% of float) but by a punitive 49.2% borrow fee and a days to cover reading of 999.99 that makes its tiny float effectively impossible to buy back at recent volume. Just behind it sits CETX at 99.7, the board's true high-conviction short squeeze profile with short interest at 77.1% of float. The broader pattern on June 8, 2026 is small-cap and cost-driven: extreme borrow fees on thin floats, with 17 of the top 25 names flagged on the FINRA threshold list.

Top 5 Most Shorted Stocks on June 8, 2026
1. OST — Squeeze Score 100
OST tops the board on cost and liquidity, not positioning. Short interest is only 3.5% of float, so this is not a crowded-trade setup — it is a borrow-and-liquidity setup. The borrow fee sits at 49.2% annualized, and days to cover reads 999.99, meaning recent volume is so thin that existing shorts could not be bought back at any reasonable pace. At $1.695, OST is a low-priced, illiquid name where the squeeze mechanic is the borrow itself: if availability tightens further or lenders recall shares, shorts face a forced exit into almost no liquidity. It is not threshold-flagged.
2. CETX — Squeeze Score 99.7
CETX is the classic crowded-short profile on the June 8 board: short interest at 77.1% of float — the highest on the list — paired with a 31.2% borrow fee and just 2.6 days to cover. It carries the FINRA threshold flag, confirming sustained short-side volume. Five-day momentum is sharply negative at -45.6%, so shorts are currently winning; the squeeze risk is a reversal — if a positive catalyst forces covering into a float that is already three-quarters shorted, the move higher would have little supply to absorb it. Price $5.08.
3. TOPS — Squeeze Score 91.4
TOPS shows 65.5% short interest of float with a 19.0% borrow fee and only 1.0 day to cover. Its float utilization mirrors the short interest at 65.5%, meaning nearly all available borrow is in use. At $0.88 this is a sub-dollar name; the low days-to-cover means shorts could in theory cover in a single session, but the high utilization and threshold flag indicate borrow is already tight. A forced recall or a volume spike on the threshold list is the mechanical catalyst here.
4. GRPN — Squeeze Score 86.5
GRPN is the highest-priced name in the top tier at $16.18 and the most liquid profile: 66.7% short interest of float but a benign 1.0% borrow fee, with 5.4 days to cover. This is a high-SI setup without cost pressure — shorts are heavily positioned but pay almost nothing to hold. It is threshold-flagged, with five-day momentum of -14.4%. Because the fee creates no urgency, a squeeze here would require a covering catalyst rather than a borrow-driven recall.
5. GOVX — Squeeze Score 63.9
GOVX is the borrow-cost outlier: a 377.0% annualized borrow fee, by far the highest on the June 8 board, against a modest 13.6% short interest of float and 1.0 day to cover. This is a pure cost-of-carry setup — positioning is light, but the fee is punitive enough that holding the short is expensive by the day. It is threshold-flagged, with five-day momentum of -39.4%. If the fee stays elevated, time works against shorts even without a price catalyst. Price $1.39.
Stocks Flagged on the FINRA Threshold List
The "T" column marks names on the FINRA threshold list — symbols showing sustained heavy short pressure on the FINRA Consolidated NMS daily short-volume file, where more than 50% of recent volume traded short-side across the last seven trading days. On June 8, 2026, 17 of the top 25 carry the flag, concentrating in the high-SI mid-cap and small-cap names rather than the single highest-fee outliers. For the full breakdown of how this flag feeds scoring, see /methodology/short-squeeze-score.
How the Tapeboard Squeeze Score Is Built
The squeeze score is a weighted composite, not a single metric: 35% short interest as a percent of float (FINRA), 25% borrow fee (IBKR), 20% float utilization, 15% days to cover, and 5% five-day price momentum (Schwab). That weighting is why a low-SI name like OST or GOVX can still rank near the top — an extreme borrow fee or float-utilization reading can carry the score even when positioning is light.
