INSM Stock Up 78% in 6 Months: Here's What You Need to Know

Insmed's stock has surged 78% in six months, largely due to the FDA approval of Brinsupri, its second marketed product, which generated $28.1 million in its first quarter. The company also benefits from steady sales of Arikayce and continues to advance its pipeline despite a recent setback in a phase IIb study. Several other biotech stocks like ANI Pharmaceuticals, CorMedix, and Castle Biosciences also show strong performance.
