“In 2025, sales to three major customers accounted for 61% of our total revenue.”
Total shares sold short and not yet covered, reported to FINRA by broker-dealers and published twice a month (bi-monthly). Days to cover divides the short position by average daily volume; a high value (above 5) can signal short-squeeze potential.
