Citadel Advisors II LLC
UK short positions the FCA published under this name: 26 companies and 179 disclosures between 9 Feb 2016 and 5 Jul 2019. Each figure is that position as a percentage of the company's issued share capital, not a money value, and percentages are not comparable or summable across companies.
This name still appears in the European registers, which do publish holders: current positions for Citadel Advisors II LLC. The two datasets are kept separate and never combined.

Frequently asked questions
- Which UK companies did Citadel Advisors II LLC short?
- The FCA's named register recorded Citadel Advisors II LLC against 26 UK companies between 2016 and 2026, across 179 disclosures. No position was still open when the register closed on 10 Jul 2026.
- Is this list current?
- No. It is a frozen archive. The FCA stopped publishing position-holder names on 13 July 2026 and now publishes one anonymous aggregate per company per day, so no new named UK disclosure exists after 10 Jul 2026. Today's UK figures are on each company's own page.
- Was this the whole of Citadel Advisors II LLC's UK short book?
- No. Only net short positions of 0.5% or more of a company's issued share capital were published with the holder's name. Smaller positions were reported to the FCA privately and never appeared in the register, so the archive is a floor, not a full book.
