Frequently asked questions
- What is short volume for SMMT?
- Short volume is the portion of daily trading volume in SMMT that was executed as short sales. FINRA publishes this data every trading day as part of the Reg SHO daily short sale volume files.
- Is short volume the same as short interest?
- No. Short volume counts short sales each day (flow), while short interest measures open short positions at a point in time (stock). A share can be sold short and covered in the same day without affecting short interest.
- What is a high short volume ratio?
- A short volume ratio above 50% means more than half of that day's reported volume was short sales. Sustained high ratios can indicate aggressive shorting pressure.
