Constellation Energy rose four percent in premarket trading after an analyst upgrade that cited the company's nuclear fleet performance and expanding clean energy initiatives. The upgrade reflects growing market recognition that nuclear energy provides stable, carbon-free baseload power—a critical advantage as utilities and policymakers prioritize grid reliability and decarbonization. We see this re-rating as justified: Constellation's nuclear assets position it to capture sustained demand for reliable power in an energy-constrained environment. The stock deserves a higher multiple on the back of its operational strengths and the structural tailwind to zero-carbon generation.
Lennar shares dropped three percent premarket after U.S. housing starts data showed a slowdown in single-family construction.

Watch the existing home sales report on Oct. 24 for further clarity on consumer demand.
Option Care Health gained two percent premarket on a strategic partnership announcement to expand home infusion services. The move taps growing demand for lower-cost care delivery outside hospital settings and should support margin expansion and market share gains in that segment.
