Novo Nordisk shares extend decline, down ~1% in Copenhagen after 8% Monday drop

Novo Nordisk shares continued to decline on Tuesday, falling about 1% in Copenhagen after an 8% drop the previous day. The sustained selloff suggests ongoing investor concerns, though the specific catalyst remains unclear from the report. This matters as Novo Nordisk is a major European pharma and index heavyweight, so sustained weakness could weigh on broader market sentiment.
