What is Citadel Securities GCS (Ireland) Limited shorting?
1 disclosed net short position of 0.5% or more across Spain, per the official registers. Positions below the 0.5% publication threshold are not public. Each position is a percentage of that company's issued share capital, not a money value: a large percentage of a small company can be less money than a small percentage of a giant.
Related register entries: Citadel Advisors Europe Limited, CITADEL ADVISORS II LLC, Citadel Advisors LLC, Citadel Securities (Europe) Limited, CITADEL SECURITIES GP LLC. The registers disclose these as separate legal entities, so their figures are never combined here.
