Merck is a buy as strong cancer drug pipeline offsets Keytruda patent expiration, Morgan Stanley says

Morgan Stanley upgraded Merck (MRK) to overweight, raising its price target to $179 from $116, citing a strong cancer drug pipeline. The bank believes Merck's pipeline, including drugs for oncology and inflammatory bowel disease, will offset the 2028 patent expiration of Keytruda. Merck shares have risen 45% year-to-date, with Keytruda generating over $16 billion in sales in the first half of 2023.
