Analyzing Daily Short Flow
Data from the FINRA Reg SHO daily short-sale volume files for the session of October 21, 2026, reveals a median off-exchange short-volume ratio of 53.2% across 3,603 covered symbols. This metric represents the daily trading flow marked as short, which includes both directional short selling and market-maker hedging activity.
Distinguishing Flow from Position
It is vital for market participants to understand that this daily short volume is not equivalent to open short interest. Much of this volume is generated by market makers providing liquidity, which is often closed out by the end of the trading session. While a high short-volume ratio can indicate heavy selling pressure, it does not necessarily reflect a long-term bearish position. Analysts should use this data to gauge intraday sentiment rather than as a proxy for total open short interest.
