Short Interest vs Short Volume
Why short interest (inventory) and short volume (daily flow) are different, and why FINRA as-of dates always appear on this site.
By Asset Trend Reports Team
Simple definition
Short interest is the reported inventory of open short positions as of a settlement date. Short volume is how much of a day’s trading was marked short.
A useful analogy
Short interest is the number of library books currently checked out. Short volume is how many checkouts happened today. Busy checkout days do not automatically mean the shelf is empty — or full.
How to read a number on this site
Short % of Float and Days to Cover come from the short-interest style snapshot and always show an as-of date from the FINRA reporting cycle — not a live tick.
We keep short volume conceptually separate so headlines that mix the two are easier to spot.
Limits
Biweekly settlement means the figure can be stale between reports. Vendor float definitions can differ slightly. Neither metric alone proves a squeeze will occur.
