Frequently asked questions
- Which UK companies did Spark Investment Management LLC short?
- The FCA's named register recorded Spark Investment Management LLC against 7 UK companies between 2025 and 2026, across 14 disclosures. 2 positions were still open when the register closed on 10 Jul 2026, the largest 0.62% of CREST NICHOLSON HOLDINGS PLC.
- 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 Spark Investment Management 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.
