Marshall Wace LLP

UK short positions the FCA published under this name: 328 companies and 14,050 disclosures between 6 Nov 2012 and 9 Jul 2026. 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.

Frozen archive. This is the pre-2026 UK named register, which stopped on 10 Jul 2026. The FCA now publishes aggregate positions only, with no holder names, so this page can never gain a new disclosure. See how UK disclosure changed in 2026. Live UK figures are on the company pages, linked below where a company is still reportable.

This name still appears in the European registers, which do publish holders: current positions for Marshall Wace LLP. The two datasets are kept separate and never combined.

Frequently asked questions

Which UK companies did Marshall Wace LLP short?
The FCA's named register recorded Marshall Wace LLP against 328 UK companies between 2012 and 2026, across 14,050 disclosures. 22 positions were still open when the register closed on 10 Jul 2026, the largest 1.34% of CERES POWER 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 Marshall Wace 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.
