On the other hand, if I recall correctly, there were several hundred thousand shares in the SEB nominee register, so a small or large player could be selling from there.
My own advice in these situations is always to keep your focus on the company’s development, except for cases where you have already planned to either buy or sell, add or reduce. In those instances, these daily or weekly buyer/seller market dynamics have relevance for timing.
Addition: most of the selling down occurred yesterday, so it won’t show up in Euroclear yet.
