What this means for investors
Novo Nordisk’s dramatic drop sent the stock to its lowest point since 2021, wiping out gains from its Wegovy weight-loss drug. The stock, which peaked in 2024, was already struggling after initial data for CagriSema disappointed.
Today’s announcement showed the drug did not come out on top in a direct comparison with Eli Lilly’s tirzepatide. People taking CagriSema achieved 23% weight loss after 84 weeks of treatment, compared with 25.5% for tirzepatide. Deutsche Bank(NYSE:DB) downgraded Novo from “Buy” to “Hold” following the trial results.
Earlier this month, Novo shares dropped after the company warned that 2026 sales could decline by 5% to 13%. Investors are now questioning Novo Nordisk’s strategy and will be watching to see if it can expand beyond diabetes and obesity drugs.
