With Biotech (XBI) up 2.1%, this looks like a sector-led move rather than a company-specific surprise.

The biotech sector moved higher, fueled by news that Germany's Merck KGaA will acquire U.K.-based Silence Therapeutics for $1.3 billion, representing a significant premium and signaling strong M&A interest in the industry. This positive sentiment was amplified by a rally in Moderna's stock, as investors anticipate the release of promising Phase 3 cancer vaccine data later in the week.
