Frequently asked questions

How shorted is UCB right now?
Disclosed net short positions total 0.50% of UCB's share capital as of 10 Sep 2026, per the FSMA's public register.
Who is shorting UCB?
No individual positions of 0.5% or more are currently disclosed for UCB.
What is UCB's short interest?
0.50% of share capital as of 10 Sep 2026. "Short interest" is the US term; the FSMA publishes each disclosed net short position of 0.5% or more by name, summed here, so it is a lower bound on all short selling in the stock.
What does this number include?
The sum of individually disclosed net short positions of 0.5% or more of share capital. Positions between 0.1% and 0.5% are reported to the regulator privately and are not public, so the true total can be higher.
How often is this updated?
Position holders must disclose changes by the next trading day; we refresh from the FSMA's register every trading day.
