Merck & Co., Inc. (MRK) gained 2.19% in Thursday's session, bringing shares to $149.54 and pushing the pharmaceutical giant's market capitalization to $361.02 billion.
The single-day advance extended a broader stretch of positive momentum. Over the past seven days, MRK has climbed 2.93%, while the 30-day window shows a comparable gain of 2.86%, suggesting relatively steady upward movement across multiple timeframes.
The consistency between the weekly and monthly figures indicates the stock has maintained its trajectory without significant reversals over the past month. Thursday's outsized daily move contributed meaningfully to those longer-term readings.
Merck shares closed out October with the stock holding well above where it began the month, capping a positive run for one of the pharmaceutical sector's largest companies by market value.
