Frequently asked questions
- Which UK companies did Magnetar Financial (UK) LLP short?
- The FCA's named register recorded Magnetar Financial (UK) LLP against 15 UK companies between 2012 and 2026, across 85 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 Magnetar Financial (UK) LLP'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.
