What Is FINRA Short Sale Volume? It Is Not the Same as Short Interest
When traders see high FINRA short sale volume, they often assume a stock is being heavily shorted. That is not always true. FINRA short sale volume can be useful as one risk clue, but it is not the same as short interest and should not be used as a standalone trading signal.
What FINRA short sale volume measures
FINRA short sale volume is daily trading-flow data reported through FINRA channels. It is not open short positions and it is not a complete picture of all market activity.
Short sale volume vs short interest
Trading flow.
Open short position.
Short sale volume is flow. Short interest is position.
How to use it in a risk checklist
How FlowHunt uses it
FlowHunt treats FINRA short sale volume as one public evidence layer. It becomes more useful when it lines up with other risk evidence such as price-volume stress, weak breadth, elevated volatility or delayed SEC evidence.
