Shares of ASML Holding fell sharply over two trading days, sliding about 12-13% in total after an industry report said a state-backed Shanghai firm has begun limited production of domestically developed immersion deep ultraviolet (DUV) lithography machines. The company’s American depositary receipts closed at $1,573.46 after a 4.82% decline on the most recent session following a 4.5% fall the prior day.
What the report said
The report, published on Jul 27, 2026, said an unnamed state-backed firm in Shanghai has achieved limited production of immersion DUV machines. The production is described as prototype-scale and behind ASML’s existing systems in terms of performance and build quality, and the machines reportedly require further testing before any mass-production ramp.
Key figures cited alongside the report include an estimated Chinese output of roughly five DUV machines in 2026, rising to about 20 machines in 2027. By contrast, ASML’s order book is described as essentially sold out through 2027, giving the company a capacity advantage measured in many more units than the handful of reported Chinese tools.
Market context and immediate reaction
The news triggered a broader decline across Asia’s chip sector. The KOSPI fell about 10% in the same session, and the Philadelphia Semiconductor Index (SOX) has underperformed the S&P 500 by roughly 18% from its peak. Traders appear to be pricing heightened geopolitical and competitive risk into semiconductor stocks, amplifying volatility.
Technical indicators for ASML at the time show daily momentum deeply negative: a two-day decline of approximately -12.5%, a daily relative strength index (RSI) around 36.1, and a commodity channel index (CCI) near -321, signaling an oversold condition on short-term charts. The monthly technical signal, by contrast, remains a Strong Buy.
Why the core business looks resilient
Despite the selloff, several structural points support a view that ASML’s leadership is intact. The company retains roughly 90% market share in lithography tools, and the reported Chinese effort so far addresses the lower end of lithography technology. The advanced extreme ultraviolet (EUV) systems used for leading-edge AI and high-performance chips are not part of the domestic Chinese machines: China’s EUV work remains at the prototype stage, and export controls have already prevented ASML’s most advanced EUV systems from reaching China.
Demand-side indicators cited by major banks also back a robust market for wafer fabrication equipment. Bank of America maintained a Buy rating on ASML shortly before the selloff and projects global wafer fab equipment spending reaching $250 billion by 2028, implying roughly 30% year-over-year growth for two consecutive years. BofA’s earnings-per-share estimates for ASML in 2027-2028 sit about 6-7% above consensus.
Additional signals of pricing power and innovation include ASML’s plans to raise prices on chipmaking equipment as recently as Jul 14, and progress with next-generation High NA EUV tools. Intel began production use of a $400 million High NA EUV tool on Jul 14 for Panther Lake chips, and the first High NA system arrived at Albany NanoTech on Jul 21. These developments represent multiple technology generations ahead of the reported Chinese DUV machines.
Analyst activity also leans supportive: twelve analysts revised earnings upward in the recent period, and ASML reported net income of 2.92 billion earlier in July 2026.
Downside considerations
There are genuine risks underpinning the market reaction. China accounts for roughly 20% of ASML’s revenue, and a gradual substitution of low-end DUV demand by domestic machines over a two- to three-year horizon could erode that revenue slice. Valuation metrics are another concern: ASML trades at premium multiples across P/E, P/B, EV/EBIT and EV/EBITDA measures, leaving limited margin for error if growth expectations shift.
Finally, the rout reflects broader sector contagion: the chip complex has been weak, and short-term sentiment has driven price action more than immediate fundamentals.
Technical snapshot
- Daily - Strong Sell: RSI ~36, MACD around -13.3, CCI -321 (oversold)
- Weekly - Neutral: RSI ~51, MACD ~131 (Buy signal), ADX indicating sell pressure
- Monthly - Strong Buy: long-term trend remains intact
Short-term support levels to observe include S1 at $1,596 (already breached), S2 at $1,538, and deeper support at $1,463. Momentum favors the downside for near-term traders, though a bounce is possible from oversold readings.
Conclusion
The emergence of a limited domestic DUV capability in China is a meaningful development, but the immediate competitive threat appears overstated relative to ASML’s current backlog and technological lead. Twenty machines projected for 2027 versus an order book measured in the hundreds represents a warning shot rather than a direct displacement of ASML’s business in 2026-2027. The recent price action reads as a sentiment-driven correction amplified by a weak chip tape, not an instantaneous re-rating of ASML’s long-term position.
Prospective investors must weigh tolerance for additional near-term headline-driven volatility against ownership of a company with dominant lithography share, an EUV monopoly at the leading edge, and tools sold out through 2027.
