ASML vs. TSMC: Better Semi Stock to Buy Right Now?

ASML and TSMC sit at the heart of the AI-driven chip boom, with ASML's EUV lithography machines driving advanced production and TSMC expanding capacity. ASML has more than doubled in the past year, up about 115%, while trading at a 53.5x trailing P/E and 15.8x price-to-sales.

TSMC remains a critical, undervalued counterplay as it scales, and demand for EUV tools could rise over the next three to five years as the global foundry market diversifies beyond TSMC. Investors face a choice between premium exposure to the equipment moat and catching a broader AI cycle with TSMC.
