Why Pfizer Stock Was so Healthy in August
Pfizer (PFE) stock rose 14% in August, outperforming peers. Q2 revenue was $15B, up 3%, and adjusted EPS was $0.77, beating estimates. The company raised its full-year revenue guidance to $60.5B-$62.5B. Regulatory wins included EMA validation for a Lyme disease treatment and FDA approval for a COVID vaccine. Eliquis, its top drug, grew 19% but faces future generic competition.
