Top Short-Squeeze Candidates Today: July 13, 2026 — 7-Factor Leaderboard
GTBIF leads Tapeboard's July 13, 2026 squeeze-score leaderboard at 46.9/100, alongside GRPN (44.9/100) as the lone name with a fully observable, FINRA-threshold-confirmed short-squeeze profile. Sixteen OTC/grey-market securities were excluded due to sentinel data.
TL;DR: As of market close on July 13, 2026, GTBIF leads Tapeboard's 7-factor squeeze leaderboard with a score of 46.9/100, with GRPN (44.9/100) the only fully-populated, FINRA-threshold-confirmed name on the board.
Tapeboard's daily squeeze scan ranked 18 stocks by composite score on July 13, 2026, combining seven factors: short interest as a percentage of float, annualized borrow fee, float utilization, the FINRA Consolidated NMS short-volume ratio, days-to-cover, five-day price momentum, and week-over-week borrow-fee change — each z-scored against a live ~500-stock universe. Sixteen of the 18 names carry an identical 43.1 composite score with no observable short interest, borrow fee, or momentum data alongside sentinel 999.99 days to cover readings — these OTC/grey-market securities have been excluded from the leaderboard below to avoid publishing degenerate composite scores. Only GTBIF and GRPN survived data-quality filtering, with GRPN standing as the session's only fully-populated, FINRA-threshold-confirmed name.

What Drove Today's Rankings
Sixteen of the 18 scanned names were excluded from the leaderboard after data-quality filtering: each carried an identical 43.1 composite score and a sentinel 999.99 days to cover reading — the model's ceiling value for names where recent volume is too thin to compute a real cover estimate — with short interest, borrow fee, and momentum data unavailable across the same set. These were OTC/grey-market securities with no reported FINRA short-interest data and no IBKR stock-loan availability, so publishing their composite would have surfaced a degenerate score driven entirely by the days-to-cover sentinel. The two names that survived filtering tell a cleaner story. GRPN, at rank 2, is the standout: it's the only leaderboard name with a full data set — 67.5% short interest, a 1.2% borrow fee, 6.1 days to cover, and confirmed FINRA threshold status — and it posted the leaderboard's only measured momentum reading, -11.4% over five days. The model's 35%/25% short-interest/borrow-fee weighting means names without that data would otherwise score primarily off whichever factors remain observable, which is precisely why the data-sparse cluster was excluded.
Top Names
1. GTBIF — Squeeze Score 46.9/100
GTBIF tops today's leaderboard with a score of 46.9/100, the session's highest reading despite having no observable short interest, borrow fee, days-to-cover, or momentum data — the score is reweighted across the remaining factors given that gap. The Pharmaceuticals-sector stock, last priced at $7.62, is not flagged on the FINRA threshold list, meaning recent short-side volume hasn't crossed the reporting threshold.
2. GRPN — Squeeze Score 44.9/100
GRPN ranks second at 44.9/100, driven primarily by short interest at 67.5% of float and a 1.2% annualized borrow fee, which together translate to 6.1 days to cover at recent volume. The Retail-sector name is confirmed on the FINRA threshold list and posted the leaderboard's only measured momentum reading, -11.4% over five days, with its borrow fee down 0.4 percentage points over the same span.
Excluded Names
Sixteen OTC/grey-market securities — including ABCCF, ABSKF, ACCEF, ACIRF, ACKAF, ACSHF and ten others — were removed from the leaderboard after data-quality filtering. Each carried an identical 43.1 composite score with no observable short interest, borrow fee, or momentum data and a sentinel 999.99 days-to-cover reading. Because short interest and borrow fee carry the two largest weights (35% and 25%) in the composite model, scores built without them are degenerate and not meaningfully comparable to the surviving names, so they are excluded by design.
Factor Breakdown: How the Score Is Built
Tapeboard's squeeze score weights five core components: 35% short interest as a percentage of float (FINRA), 25% borrow fee (IBKR), 20% float utilization, 15% days to cover, and 5% five-day momentum (Schwab), each z-scored against a live ~500-stock universe before being combined into the 0-100 composite. The FINRA Consolidated NMS short-volume ratio and week-over-week borrow-fee change feed into the same model as contextual flags rather than as separately weighted components. The composite is built to surface short squeeze potential across the universe scanned each day, not to forecast whether any individual name will actually squeeze. Full weight definitions and z-score methodology are documented in the methodology.
Frequently Asked Questions
What are the top short-squeeze candidates today?
Tapeboard's top squeeze-score names on July 13, 2026 are GTBIF (46.9/100; short interest and borrow fee data unavailable) and GRPN (44.9/100; 67.5% short interest and a 1.2% annualized borrow fee). Sixteen OTC/grey-market securities were excluded from the leaderboard after data-quality filtering due to missing short-interest, borrow-fee, and momentum data paired with sentinel 999.99 days-to-cover readings.
How does Tapeboard calculate its squeeze score?
Tapeboard z-scores each factor against a live ~500-stock universe, then combines them into a single 0-100 composite weighted 35% short interest as a percentage of float, 25% borrow fee, 20% float utilization, 15% days to cover, and 5% five-day momentum, with FINRA short-volume threshold status and week-over-week fee change as contextual flags.
When does short-interest data update?
Short interest lags roughly two weeks per the FINRA settlement schedule, so today's reading reflects the most recent settlement date rather than July 13 itself. Borrow fee data updates next-day from IBKR stock-loan availability.
