Understanding Daily Short Volume
FINRA's Daily Short Sale Volume files provide a critical look at the flow of short selling activity. Unlike bi-monthly short interest reports, which capture open positions at a specific point in time, these daily files aggregate the volume of trades marked as 'short' reported to FINRA's Trade Reporting Facilities (TRFs), the ADF, or the ORF.
Data Utility
This data is essential for analysts looking to identify spikes in short-selling pressure on a daily basis. It is important to note that this data is not consolidated with exchange-reported short volume, meaning it represents a subset of total market activity. Analysts should use this as a proxy for daily sentiment and flow rather than a definitive measure of total open short interest.
