Factor Breakdown: How the Score Is Built
Tapeboard's Short Squeeze Score (setup v6, since 2026-10-07) gates on short interest of at least 15% of float (FINRA settlement, point-in-time and split-safe), then ranks gated names 0-100 on 20-day volatility with the single largest daily move excluded (60%), 5-day float rotation (20%) and last-session relative volume (20%), each as a percentile among the gated names. A higher score means higher historical odds of a large move in either direction; it is not a directional call. Borrow fee, days to cover and the short-volume ratio are shown for context at zero weight. Data are sourced from FINRA, the SEC, and the NYSE and NASDAQ exchanges. Read the full methodology.

How does Tapeboard calculate its squeeze score?
The score gates on short interest of at least 15% of float (FINRA settlement, point-in-time), then ranks gated names 0-100 on 20-day volatility with the single largest daily move excluded (60%), 5-day float rotation (20%) and last-session relative volume (20%), each as a percentile among the gated names. Borrow fee, days to cover and the short-volume ratio are shown for context at zero weight. The full formula, the gate and the calibrated odds are published at the methodology page.
When does short-interest data update?
Short interest lags about two weeks, following the FINRA settlement schedule. Borrow fees update next-day from stock-loan data, and the FINRA short-volume threshold list updates daily.
