Frequently asked questions

- Disclosed net short positions total 0.62% of ARGENX's share capital as of 12 Oct 2026, per the FSMA's public register. That makes it the 11th most shorted Belgian stock, out of 13 companies with disclosed positions.
- Who is shorting ARGENX?
- The FSMA names each holder of a position of 0.5% or more. Currently disclosed: MARSHALL WACE LLP.
- What is ARGENX's short interest?
- 0.62% of share capital as of 12 Oct 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.
