Stock Market Update

[BRIEFING.COM] The major averages continue to plot a lower course as the session progresses. 

Gilead Sciences (GILD 150.10, -1.30, -0.86%) is expanding its oncology and cell therapy footprint through a definitive agreement to acquire Arcellx (ACLX 113.92, +49.80, +77.69%), deepening a collaboration that began several years ago. The transaction gives GILD full strategic control over a promising late-stage CAR-T program in multiple myeloma and strengthens its long-term position in hematologic malignancies. Management views the deal as a way to streamline development, capture full economics, and build on its growing cell therapy platform. GILD is paying $115 per share.

In other stock-specific news, Domino's Pizza (DPZ 397.07, +12.46, +3.24%) is trading higher following its 4Q25 report, as investors look past mixed headline results and focus on strong same-store sales momentum, continued market share gains, and confidence in 2026 growth. The quarter reinforced that DPZ's "Hungry for MORE" strategy is driving traffic and share gains even in a pressured macro environment, helping offset near-term margin headwinds and supporting a meaningful dividend increase.
