Trung Huynh, a top 9% analyst from RBC Capital downgrades MRK to a hold rating and raises their MRK price target from $142.00 to $150.00, on Aug 20, 2026.
RBC Capital's Trung Huynh downgraded their rating on Merck & Co (NYSE: MRK) from Buy to Hold on 2026/08/20. The analyst also raised their price target by 5.6% from $142 to $150.
According to Huynh, Merck's cancer vaccine data beat expectations, reinforcing the company's ongoing strong momentum.
However, the analyst pointed out that the stock is trading at an "unprecedented valuation" of $150 per share, which is quite high for a business that will see a substantial loss of exclusivity in two years and "modest" growth in the interim.
Because of "already elevated expectations," Huynh cautioned that the pace of Merck's pipeline progress must increase for the stock price to rise from here.
The analyst called the stock fairly priced at its current valuation.
