Understanding Short Sale Flow
FINRA provides critical daily short sale volume files that aggregate data for all short sale trades executed and reported to the TRF, ADF, or ORF. It is vital for analysts to distinguish this data from open short interest. This daily volume represents the 'flow'—the number of shares marked short on a specific trade date—rather than the total size of open positions.
Data Accessibility
These files are published no later than 6:00:00 PM ET on the relevant trade date. The consolidated files combine volume for trades in exchange-listed securities, providing a comprehensive view of daily short-selling pressure. Analysts use this data to identify spikes in short-selling activity that may precede broader market moves or indicate institutional hedging strategies. For the most accurate analysis, this flow data should be cross-referenced with bi-weekly official short interest reports.
