About this data

FINRA collects short interest (shares sold short and not yet bought back) twice a month and publishes it by security. Days to cover (short shares ÷ average daily volume) estimates how many days of normal trading it would take short sellers to close their positions — a high value is a classic short-squeeze setup. This is true short interest, distinct from daily short-sale volume (which includes market-maker hedging). See also this security's fails-to-deliver.
