Merck stock closed at USD 146.63 on the New York Stock Exchange on September 19, 2026, down 0.3 percent. The move left Merck & Co. Inc. (ISIN US58933Y1055) trading about 6.6 percent below its 52-week high of USD 156.92.
September 19, 2026 in numbers
The shares moved between USD 145.74 and USD 147.84 during the session and ended near the upper half of that range. A retail brokerage quote page showed the same close and put Merck's market value at USD 362.11 billion.
Broad market sentiment was firmer, with the S&P 500 ending the session at 7,650.50, up 0.17 percent. That left Merck below the index on the day, even as health care names were mixed in the broader tape.
Today after the launch
On September 18, 2026, Merck said it launched Merck 'Your Hive of Whole Health' and said the program will be featured at USCHA. That event remains the main company-specific item tied to today's session. Brent crude futures also fell on Monday morning, a market move that can matter for health care risk appetite, according to Reuters.
