Frequently asked questions

Which Dutch stock saw the biggest rise in short interest over the past year?
Akzo Nobel N.V.: up 9.65 percentage points to 11.67% as of 12 Oct 2026, per AFM data. The full lists are on this page.
How are these changes calculated?
Each company's latest published figure is compared with its figure on the anchor date, or the nearest position date before it. Changes are percentage points of the company, not percent of the earlier figure. A company is compared only when it has a published figure at both ends; one that was absent on either date is left out rather than counted as zero.
Does a rise mean the stock will fall?
No. These are disclosed positions, published with a delay, and a position can be a hedge rather than a bet. Nothing here is investment advice and none of it predicts anything.
