ASML Stock Isn't Cheap, but It Might Still Be a Bargain

ASML is trading at 35.1x 2027 projected EPS with analyst estimates of $29.69 EPS in 2026 and $37.51 in 2027 (consensus growth of ~26.3%). EUV systems now drive margin and revenue expansion (EUV = 56.1% of net bookings in Q4 2025, only two high-NA units sold), while servicing (mostly DUV) contributes ~25% of revenue. Shares are up 79.5% over the last year, reflecting AI-driven demand and ASML's durable, hard-to-replicate EUV moat (over €6bn invested and 17 years of development). Valuation appears extended, so near-term cooling is possible, but the company has a clear long-term growth runway tied to AI chip fab investment.

Analysis

ASML’s moat gives it idiosyncratic, lumpy revenue timing: multi-year lead times and installation schedules turn what looks like steady secular demand into binary booking events. That amplifies headline volatility — a single large fabs’ cadence shift or a supplier constraint can move a year (or more) of expected revenue into the next quarter, producing sharp EPS revisions despite long-run secular strength.

Second-order winners are not just fab owners but firms that sit inside the precision supply chain and aftermarket ecosystem — precision optics, vacuum/subsystem integrators, and high-service-cycle parts benefit from higher fleet complexity and longer installed-base lifetimes. Conversely, buyers of legacy or used lithography (and smaller IDM fabs that can’t finance high-NA ramps) will face higher unit costs and potential competitive disadvantage, accelerating consolidation toward big foundries.

Key catalysts to watch in the next 6–18 months are component availability and policy risk: restrictions on specific subsystems or export licensing delays can mechanically cap near-term shipments and shift value between regions and suppliers. Downside is front-loaded and fast (quarter-to-quarter booking collapses), while upside requires sustained, multi-year capex follow-through — that asymmetry argues for option structures rather than outright longs at current sentiment.

The market appears to be pricing long-term perfection; that leaves an attractive set of asymmetric trades where upside is captured in multi-year spreads and downside is hedged, or where you express exposure to fabs and AI demand without concentrating on the single-equipment vendor risk.

Key Decisions for Investors

• Buy ASML 12-month call spread (long 12m call ~15% OTM, short 12m call ~40% OTM). Rationale: captures multi-year EUV adoption upside while capping premium; expected cost ~3–6% of notional, target gross upside 20–40% (3–6x premium). Roll or unwind on a >15% drawdown or on clear signs of component-export easing.
• Pair trade: Overweight TSM (buy and hold 12–24 months, 1.5–3% portfolio) and reduce ASML directional exposure (sell 6–12 month ASML calls or buy puts sized to 50% of ASML notional). Rationale: captures fab-level demand even if equipment bookings slip; target 30–50% upside for TSM if foundry capex continues, while the ASML hedge protects against booking lumpiness.
• Hedge geopolitical/component tail: Buy 18-month ASML puts sized to 25–50% of existing ASML exposure (limit premium to ~2–4% of portfolio). Rationale: protects against rapid rerouting of sales or export controls; acceptable cost for insurance given asymmetric downside.
• Income/volatility play for holders: Sell 4–8 week covered calls on ASML around key booking/earnings dates to harvest elevated premium; if neutral-to-slightly-bearish, size to 5–10% of position and close on >10% adverse move. Rationale: monetizes short-term optimism while keeping long-term optionality intact.
