The FCA's Reportable Shares List

The Reportable Shares List (RSL) is the FCA's official list of the share classes in scope for UK net short position reporting. If a share is on the list, positions in it must be notified to the FCA and feed the daily aggregate net short position publication; if it is not, no UK short-position disclosure applies to it at all. The list holds 1,387 share classes as of 2 Oct 2026, the date on the FCA's own file. All 1,387 are listed below, and 478 of them have a short-position page here.

How it works

• Who maintains it: the FCA, under the UK's post-2026 short-selling framework. It replaced the EU-inherited scope rules that depended on where a share's main trading venue was.
• How often it changes: the FCA updates the list monthly, on the first working day. New admissions to UK venues join it; delistings and corporate actions drop off it. A company that changes its ISIN, after a scheme of arrangement for example, leaves under the old one and joins under the new one.
• Why it matters for the data: a company can only ever appear in our UK league table if its shares are on the RSL. A company leaving the list stops being reportable; its short data ends, whatever positions existed.

How we use it

Every UK ingest asks the FCA for the file's date and stores a new capture when the FCA has published one, so this page follows the monthly update. Removals also show on the new & leaving page, because a disappearance from the league can mean two very different things: positions genuinely closed, or the share simply left the reportable universe. Conflating those would misread the data, so we keep them distinct.

Recently removed

The 16 share classes on the FCA's own "recently removed" sheet, newest first. A removal ends UK short-position reporting for that share class from the date shown.

The full list

Every share class on the FCA's list as of 2 Oct 2026, by company name. "Date added" is the FCA's own column: the day the share class entered the reportable universe, which for most is the day the regime started.
