As of 15 September 2026, 42,361 UCB Unsponsored ADR (Belgium) shares were held short — the total across every reporting firm, not one fund's position. That is 27,405 shares more than the previous report, a 183.24% increase. At the average daily volume of 100,514 shares, that position represents 1.00 days of trading — what the filing calls days to cover.
This is the most recent figure that exists, and it is 17 days old. FINRA collects short interest twice a month, on a settlement date, and publishes it about eight business days later. So nobody has a live short-interest number for UCBJY — not us, and not anyone quoting one. We print the settlement date on the figure so you always know which day you are looking at.
Across the 12 reports we hold, the position has risen from 27,204 shares on 31 March 2026 to 42,361 today, a change of 55.7%. The highest reading in that window was 42,361 shares on 15 September 2026.

- What is UCBJY's short interest?
- 42,361 shares, as of the 15 September 2026 settlement date. That is the figure FINRA published, unadjusted.
- What percentage of the float is short?
- We do not publish that, because FINRA does not publish float. The regulator reports the number of shares held short; turning it into a percentage needs a share count from somewhere else, and different sources disagree about what counts as float. We would rather give you the number that was actually filed than a percentage built on an assumption.
- How current is this?
- It is 17 days old, and that is as fresh as short interest gets. FINRA measures it twice a month and publishes it seven business days after the settlement date. Any site showing you a "live" short interest figure is showing you something else.
- What does days to cover mean?
- It is the short position divided by average daily trading volume — here, 1.00. It describes how many days of ordinary trading the position is equivalent to. It is arithmetic from the filing, not a prediction about what will happen.
- Where does this come from?
- FINRA's consolidated short interest file, which is public. We read it directly and store it unchanged, except that we blank the days-to-cover placeholder FINRA writes when a stock has almost no volume.
