Cenergy Holdings is trading at €22.50, down 5.22%, after a broad European sell-off on October 8. - The pan-European STOXX 600 fell 0.75% as a bond sell-off and elevated oil prices stoked inflation and growth concerns. - Reuters reported Middle East supply worries and rising yields weighed on European shares. - No fresh company-specific catalyst clearly explains the decline. The €10 million buyback, announced September 16 for share-based remuneration, was not a new October 8 event.
