Positioning score 63.5 + catalyst boost 0 (total capped at 100). This is a screening index, not a probability of a squeeze.

Method and coverage limits

Factor percentiles compare eligible primary operating-company stocks reporting short interest at the latest settlement date (2026-09-15). The weighted mean uses short interest 30%, days to cover 20%, price vs VWAP 15%, short-volume trend 15%, short-interest change 10%, and fails-to-deliver 10%. Missing factors redistribute their weight; incomplete coverage is not evidence of low risk. Price, volume, and earnings boosts add 10 each, capped at 20.

Shares outstanding are not free float. Borrow fees, utilization, lendable supply, recalls, and dealer inventory are not measured. Short-sale volume does not measure the change in open shorts; fails to deliver are not a borrow-cost measurement; price vs VWAP does not establish short sellers' entry prices. Earnings can move prices in either direction.

The weights are judgment-based, not calibrated to future squeeze outcomes. The separate options assessment below does not change this universe ranking.

Options positioning & squeeze sensitivity

Nearest expiration after today within 30 calendar days; same-day expirations and later maturities are excluded.

The selected options expiration is incomplete or temporarily unavailable.

Open interest has both a buyer and a seller; it does not reveal dealer hedge direction. Gross gamma sums both calls and puts without netting and uses a local 1% price-change approximation. It measures sensitivity, not predicted buying or a squeeze probability.

Assessment prepared 2026-10-06 11:00 UTC. Options model values may come from a cached snapshot; their original computation time is not supplied. Open interest has its own effective date.
