Published July 29, 2026 · ASML chart, levels and live analysis

Key Updates

ASML shares have declined a further 2.45% since the July 28 report to $1,539.06, extending the near-term drawdown to approximately 7.7% from the post-earnings peak and deepening the 1-month loss to -18.27%. The selloff is occurring against a backdrop of unchanged fundamentals: the July 15 guidance upgrade — full-year revenue raised to €43–45bn, gross margin lifted to 54–56% — remains intact, and no new adverse corporate developments have been reported. The correction appears to reflect profit-taking and valuation consolidation following a YTD run that reached nearly 80% at its peak, rather than any deterioration in the underlying investment case.

Current Trend

The short-term trend is unambiguously negative across all near-term timeframes: -2.77% (1d), -14.58% (5d), and -18.27% (1m). However, the medium- and longer-term picture remains constructive: the 6-month return stands at +5.77% and YTD performance at +43.86%, confirming that the broader uptrend established earlier in 2026 is intact despite the current drawdown. The sequential price action — $1,630 → $1,664 (+2.11% bounce) → $1,578 (-5.20%) → $1,539 (-2.45%) — shows a pattern of lower highs and lower lows over the past week, with each attempted recovery failing to reclaim prior support levels. The $1,577–$1,630 zone, which previously acted as support, has now flipped to resistance. The current price of $1,539 is testing new near-term lows within the correction phase.

Investment Thesis

The core investment thesis rests on ASML's structurally unassailable position in the semiconductor equipment supply chain: a monopoly in EUV lithography and >80% share in DUV systems, with no credible near-term competitor in high-end segments. Demand is being driven by AI-related capital expenditure from hyperscalers and leading chipmakers (TSMC, Samsung, SK Hynix, Intel, Micron), creating a multi-year equipment supercycle. The company's planned capacity expansion — EUV output +30% in 2027 and a further +30% in 2028 — underpins a revenue trajectory toward €70bn+ by 2028, with Morningstar's revised fair value estimate of EUR 1,800/share providing a fundamental anchor. The thesis is a long-duration, high-conviction play on AI infrastructure build-out with a near-monopoly toll-road business model.

Thesis Status

The investment thesis remains fully intact. The current -18.27% 1-month correction is a valuation consolidation event, not a fundamental deterioration. Key thesis pillars — guidance upgrade, EUV monopoly, expanding capacity, memory revenue surge of 75% projected for 2026, and a rising Morningstar fair value target of EUR 1,800 — have all been reaffirmed within the past two weeks. Speculation around ASML becoming Europe's first trillion-dollar company (current market cap ~$700bn per Reuters) reflects the market's recognition of the long-term earnings power. The primary risk to thesis continuity remains execution risk on capacity expansion and potential demand softening from hyperscalers, neither of which has materialized in the reported data. At $1,539, the stock trades at a meaningful discount to Morningstar's EUR 1,800 fair value, widening the margin of safety relative to prior reports.

Key Drivers

The following key drivers are shaping ASML's near-term and medium-term trajectory:

Technical Analysis

ASML is in a well-defined short-term downtrend, printing a sequence of lower highs and lower lows since the post-earnings peak. The $1,577–$1,630 band — previously a key support zone identified in prior reports — has now transitioned to resistance following the failure to reclaim it during the July 27 bounce to $1,664 and the subsequent rejections. The current price of $1,539 represents a new intra-correction low. There is no identifiable near-term technical support from the provided price data below current levels; the next meaningful reference point would be the pre-earnings consolidation range. On the upside, $1,577–$1,630 is the first resistance cluster to reclaim for any bullish reversal signal. The YTD gain of +43.86% confirms the primary trend remains bullish on a longer timeframe, and the current drawdown (-18.27% over 1 month) is consistent with a healthy correction within a strong uptrend rather than a trend reversal. Volume and momentum indicators are not available in the provided data.
