Why these names moved could not be confirmed in today’s data; each is still marked as having no identified driver.Samsung Electronics carried a shareholder-return news line in early trade, but that marking is absent from the current data.No cause is attached here. Once flows and disclosures are filled in after the close, they will be looked at again.
