ERO · Ero Copper Corp.
Total shares sold short and not yet covered, reported to FINRA by broker-dealers twice a month. Each reading settles on the 15th and the last business day of the month and is published seven business days later — the next scheduled dates are listed at the top of the table. Days to cover divides the short position by average daily volume; a high value (above 5) can signal short-squeeze potential.
Peer-relative percentile rank across all stocks reporting short interest at the latest settlement date (2026-07-15). Weighted mean of the available factors (short interest 30%, days to cover 20%, price vs VWAP 15%, short-volume trend 15%, short-interest change 10%, fails-to-deliver 10%) plus catalyst boosts (price spike, volume surge, earnings within days), capped at +20 and clamped to 100.
