About this data

FINRA publishes daily consolidated (CNMS) short-sale volume — the share of each day's reported trading volume that was marked "short." This page aggregates the rolling ~60-trading-day window. Important: short volume includes bona-fide market-maker hedging and is not the same as short interest (shares sold short and not yet covered); high percentages are common and routine. For settlement failures on this security, see its fails-to-deliver.
