Why Is Merck Stock Still An Undervalued Mega-Cap In Pharma?

Merck (MRK) stock surged 73% in the past year, outpacing the S&P 500, driven by successful clinical trials and FDA approvals. The company's pipeline, including LIPFENDRA and an mRNA cancer vaccine, addresses concerns about KEYTRUDA's patent expiration. Merck's forward P/E of 16x is lower than peers like Johnson & Johnson (JNJ) and Eli Lilly (LLY), suggesting potential undervaluation.
