Most Shorted Stocks Today: April 29, 2026 — Top 25 Squeeze Candidates
RAYA tops Tapeboard's most shorted stocks leaderboard on April 29, 2026 with a perfect 100 squeeze score and a 286.2% annualized IBKR borrow fee, leading a board where 19 of the top 25 names sit on the FINRA short-volume threshold list.
On April 29, 2026, RAYA tops Tapeboard's short-squeeze leaderboard with a maximum score of 100, driven by a 286.2% annualized IBKR borrow fee, 100% float utilization, and 0.04 days to cover at recent volume. Nineteen of the top 25 names are flagged on the FINRA Consolidated NMS short-volume threshold list, and 22 of the 25 are trading lower over the past five sessions — broad short-side pressure, not isolated single-name interest. Borrow costs cluster low outside the very top of the board, which puts most of today's squeeze risk on float utilization, days to cover, and SI%Float reaching levels where mechanical covering — not voluntary covering — drives the tape.

Top 5 Most Shorted Stocks on April 29, 2026
1. RAYA — Squeeze Score 100
RAYA tops the board with a 286.2% annualized IBKR borrow fee, 100% float utilization, and 0.04 days to cover at recent volume. SI%Float is small at 8.0%, but maximum utilization combined with a triple-digit fee describes a stock-loan market that is effectively closed — every available share is on loan, and shorts are paying punishing carry to keep the position open. Price sits at $3.60 with -2.6% five-day momentum. If borrow availability tightens further or a single buyer steps in for size, cost-to-stay-short rises fast and covering becomes the only release valve. Threshold-flagged.
2. GRPN — Squeeze Score 84.2
GRPN runs second on the strength of one dominant input: 51.7% of float held short. Days to cover is 9.07, float utilization 47.4%, and the borrow fee is only 0.78% — shares remain cheap to borrow despite the SI%Float reading. Price is $13.96 with -10.6% five-day momentum. This is the textbook high-SI / low-fee profile: shorts have built a large book without paying up, which means a positive catalyst is what mechanically forces covering rather than mounting borrow cost. Not threshold-flagged.
3. PLAY — Squeeze Score 80.1
PLAY shows 60.7% SI%Float — the highest reading on the entire board — with 33.6% float utilization and 3.89 days to cover. Borrow fee is 0.51% at $11.13 with -13.8% five-day momentum. Threshold-flagged. Low days-to-cover means concentrated short volume can clear quickly on the way up; the mechanics here run on an SI%Float pushing the practical limit of the borrow market against a name where shorts can in fact be unwound — but only in a hurry if forced.
4. RUM — Squeeze Score 74.6
RUM carries 26.0% SI%Float, 26.0% float utilization, and 17.46 days to cover — among the highest DTC readings in the top 25. Borrow fee is unavailable, price is $6.71, and five-day momentum is essentially flat at -0.7%. Not threshold-flagged. Days-to-cover is the dominant driver: at recent volume it would take more than three trading weeks for shorts to exit, so any forced unwind has to fight thin liquidity. The squeeze trigger here is volume — anything that brings buyers in size compresses cover time and lifts the floor.
5. INDI — Squeeze Score 70.5
INDI is the only name in the top 5 with positive five-day momentum at +20.3%. SI%Float is 30.6%, float utilization 31.3%, days to cover 18.36, borrow fee 5.44% at $4.09. Threshold-flagged. The combination — high DTC, mid-single-digit fee, and an upward move already in progress — is the most active squeeze profile on the board. Shorts that added into strength now face rising carry and a tape moving against them; further upside forces price-in covering rather than waiting for a discrete catalyst.
Highest Borrow Fees on April 29, 2026
RAYA is the borrow-fee outlier at 286.2%. Outside the top of the table, the highest-fee names are INDI at 5.4%, IBRX at 5.1%, and RXRX at 4.2%. The rest of the leaderboard borrows below 1.5%, which means today's squeeze setups are driven by float utilization and days-to-cover — not borrow-cost duress.
Stocks Flagged on the FINRA Threshold List
The T column flags symbols on the FINRA Consolidated NMS daily short-volume threshold list — names where short volume has been at least 50% of total reported volume on a sustained basis within the last seven trading days. T is a real-tape pressure signal, separate from the headline SI%Float reading. Today, 19 of the top 25 candidates carry the flag. See /methodology/short-squeeze-score for the full scoring breakdown.
How the Tapeboard Squeeze Score Is Built
The Tapeboard squeeze score is a weighted blend: 35% short interest as a percentage of float (Yahoo), 25% borrow fee rate (IBKR via iborrowdesk.com), 20% float utilization, 15% days to cover, and 5% five-day price momentum (Schwab). Each input is normalized and capped before weighting; the full formula and clamps live at /methodology/short-squeeze-score.
