Cerillion PLC short interest

From the Financial Conduct Authority’s short-selling disclosures. Until 9 Jul 2026 the FCA published every individual net short position of 0.5% or more, with the fund’s name. Since then it publishes each company’s aggregated net short position only. We cover the UK-listed companies we can match to a listing. FCA short-selling disclosures · FCA aggregated net short positions (CSV)

The short positions held against a company, net of any long positions the same holders hold, as a percentage of its issued shares. A figure of 5% means disclosed sellers are short shares equal to 5% of the company.

That is when the FCA stopped publishing named positions. Every fund figure here is dated: it is the last-known book, not a fund’s current position. Every figure after that date is the FCA aggregate, which names no one.

Building means the 8-day average of the net short is above its 35-day average and rising; covering is the opposite. A trend flip is when those two averages cross. Changes are in percentage points.

Named positions were only published at 0.5% or more. When a fund disappears from the register, its position fell below that line. It may not have closed completely.

The FCA updates its lists each weekday. Disclosures lag by at least one trading day, and we refresh in the evening, UK time. Information only, not investment advice.
