ASML vs. QCOM: Which Semiconductor Stock is the Better Buy Now?

ASML is favored over Qualcomm on materially stronger 2026 estimates: ASML sales are projected to grow 36% and EPS 61%, with EPS consensus up 22.9% in 60 days, versus Qualcomm sales and EPS declines of 2.8% and 12.4%, respectively. ASML plans to expand 2027 Low-NA EUV capacity by about 30% from roughly 65 systems and immersion DUV capacity by about 30% from roughly 130 systems, reflecting sustained AI-driven customer commitments. ASML shares have gained 115% over the past year versus Qualcomm's 9.2%, although ASML trades at a higher 11.61x forward sales multiple compared with Qualcomm's 4.18x.

Analysis

The relevant distinction is not “AI exposure” but position in the capital-intensity stack. ASML monetizes each leading-edge node transition regardless of which compute architecture wins, while QCOM must win OEM sockets and prove that its PC/server designs can earn attractive margins against entrenched x86 and accelerator ecosystems. This makes ASML’s earnings revisions more durable but also makes its valuation unusually sensitive to any 2027 wafer-fab-equipment order deferral; a modest reduction in customer capex can cascade into lower tool utilization and multiple compression.

QCOM’s near-term estimates likely understate the optionality of custom silicon, but that optionality should not be capitalized before design-win scope, volume commitments, and gross-margin structure are disclosed. Its more immediate earnings risk is the interaction of tight memory supply with Chinese Android demand: higher BOM costs can pressure handset sell-through and OEM chipset purchasing simultaneously. Conversely, memory normalization or better-than-expected Windows-on-Arm adoption could produce a 1-3 month estimate-revision trade because QCOM’s current expectations are comparatively undemanding.

The consensus appears to treat ASML’s backlog visibility as equivalent to revenue certainty. The more important variable is whether foundry and memory customers convert reservations into installations on schedule, particularly if AI demand broadens less rapidly from training to inference. Over 6-18 months, advanced packaging and memory bandwidth may absorb a growing share of AI capex, benefiting equipment peers such as AMAT, LRCX and KLAC even if leading-edge lithography spend remains strong; ASML is the highest-quality bottleneck but not necessarily the best marginal AI-capex beta after a large rerating.

Key Decisions for Investors

• Maintain a core ASML long only with defined downside protection: initiate/retain exposure on a 8-12% pullback or through a 3-6 month put spread. Target 15-20% upside over 6-12 months if order conversion supports 2027 capacity utilization; exit/reduce if quarterly net bookings weaken materially for two consecutive quarters or management qualifies capacity plans.
• Prefer a relative-value AI equipment basket—long AMAT/LRCX/KLAC versus a smaller ASML weight—over the next 6-12 months. This captures potential broadening into deposition, etch, inspection and packaging while reducing single-company EUV delivery and export-control risk.
• Do not initiate a directional QCOM long solely on custom-silicon headlines. Set an alert for disclosed hyperscaler volume, program economics, and incremental revenue guidance; a confirmed, margin-accretive program plus stabilization in handset guidance would support a 3-6 month long QCOM versus short SOXX or a higher-multiple PC-semiconductor peer.
• For a tactical pair, long QCOM / short ASML is only attractive after a further ASML multiple expansion without corresponding bookings acceleration. Use a 1-3 month horizon and stop out if ASML reports stronger-than-expected bookings or QCOM cuts handset/custom-silicon outlook; this is valuation mean reversion, not a structural reversal.
