Before 2026: the named era
Reconstructed from the frozen named register: the sum of individually disclosed positions of 0.5% or more in Impax Asset Management Group PLC at each disclosure date, back to 9 Apr 2024. This is a lower bound and a different measure from today's aggregate above, because positions between 0.1% and 0.5% were reported to the FCA but never published with names, so the two series are charted separately and are not comparable point for point. See the methodology.
Who was short Impax Asset Management Group PLC?

- It is the sum of every individual net short position amounting to 0.2% or more of the company's issued share capital, as notified to the FCA. Smaller positions are not counted, so total short interest can be somewhat higher.
