Before 2026: the named era

Reconstructed from the frozen named register: the sum of individually disclosed positions of 0.5% or more in IBSTOCK PLC at each disclosure date, back to 18 Jul 2018. 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.

Frequently asked questions

How shorted is IBSTOCK PLC right now?
14.25% of IBSTOCK PLC's issued share capital was sold short as of 9 Oct 2026, per the FCA's aggregate net short position publication. That makes it the 2nd most shorted UK stock, out of 421 companies with disclosed positions.
What is IBSTOCK PLC's short interest?
14.25% of issued share capital as of 9 Oct 2026. "Short interest" is the US term; the FCA publishes the aggregate net short position, the sum of every disclosed position of 0.2% or more, so it is a lower bound on all short selling in the stock.
What does this number include?
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.
Which funds are shorting IBSTOCK PLC?
Since 13 July 2026 the FCA no longer publishes position-holder names, only the aggregate per company. The final named register (as of 10 Jul 2026) listed 13 funds with positions of 0.5% or more in IBSTOCK PLC, led by JPMorgan Asset Management (UK) Ltd at 2.70%; the full final list is preserved on this page.
