How to read this: a higher score means a more crowded, harder-to-cover short base that is still building while price reclaims its 50-day moving average — the classic squeeze setup. Days-to-cover is recomputed as shares-short / average-daily-volume (FINRA floors its own value at 1.00); the z-score compares it to the ticker's own history. Short interest is reported fortnightly with a ~2-day publication lag, so treat this as a swing-horizon watchlist, not an intraday signal.
