ASML Holding N.V. (ASMLF) vs UnitedHealth Group Incorporated (UNH)

ASML Holding NV is the global leader in semiconductor lithography systems, with an estimated 90% market share. Lithography is the process of using a light source to project circuit patterns from a photomask onto a semiconductor wafer. This technology enables chipmakers to pack more transistors into the same silicon area, and it has historically accounted for a significant share of the cost of producing leading-edge chips. ASML outsources the production of most components and primarily operates as an assembler. Its largest customers include TSMC, Samsung, Intel, SK Hynix, and Micron.

UnitedHealth Group Incorporated is among the world’s largest private health insurers, providing medical benefits to roughly 51 million members globally as of December 2025, including about 1 million outside the United States. A leading provider of employer-sponsored, self-directed, and government-supported health plans, the company has built substantial scale in the medical insurance market. In addition to its core insurance operations, UnitedHealth’s Optum businesses expand its reach across healthcare services, spanning pharmacy benefits, outpatient care, and analytics for affiliated organizations and third-party clients.
