Healthcare stocks edged up amid quiet trading, mixed after-hours moves, and limited catalysts.

Health care stocks ended slightly higher after a quiet trading session with no major news, despite early declines. Arcadia Biosciences fell after ending its merger with Roosevelt Resources, while Moderna dropped without explanation. After-hours trading saw significant volatility, with gains led by Can Fite Biofarma, Bristol-Myers Squibb’s CELGR, and Greenwich LifeSciences, while BioAtla, Dermata Therapeutics, and others declined. Overall, sector movement reflected limited catalysts and holiday market lull.
