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.
