ASML Holding NV (NASDAQ:ASML) shares are tumbling Monday, on pace for its steepest single-day decline since early June, after reports that China has begun manufacturing its own immersion deep ultraviolet lithography machines. Here’s what you need to know.

China Begins Mass-Producing Homegrown Chip Fabrication Equipment
The Information reported Monday that a Chinese manufacturer operating with state backing, whose name was kept out of the story given the sensitivity of the situation, has entered production of domestically developed immersion deep ultraviolet lithography systems. Deliveries are expected to reach some of China’s most prominent chipmakers before the year is out, according to Reuters.
The significance of the development lies in what these machines represent for China’s semiconductor ambitions. Immersion DUV systems are the most capable lithography tools Chinese manufacturers can still legally obtain after export controls closed the door on ASML’s more advanced EUV technology.
A homegrown version, even one that requires further refinement before it can match ASML on throughput and consistency, hands Chinese chipmakers a fallback option that does not depend on foreign suppliers, which matters enormously as Washington weighs tightening its restrictions on lithography equipment sales and servicing in China even further.
ASML: When A Long-Term Uptrend Meets Short-Term Pressure
Technically, the setup looks more like a trend under pressure than a trend that has failed. ASML is 7.9% below its 20‑day SMA and 5.4% below its 50‑day SMA, yet still 4.6% above its 100‑day SMA and 19.6% above its 200‑day SMA. That mix signals that long‑term demand is still present while short‑term traders are stepping back to see how the tape behaves.
Momentum is guiding the tone. MACD sits below its signal line and the histogram is negative, which indicates fading upside pressure compared with the prior upswing. Rallies often struggle until momentum reclaims that baseline.
The timing adds context: the stock posted a swing high in June near the 52‑week high zone and a swing low in May, and this slide follows a June breakout attempt that failed to hold. The moving‑average stack remains constructive, with the 20‑day above the 50‑day and the 50‑day above the 200‑day, so the real question is whether this is a routine reset or the early stage of a deeper trend shift.
- Resistance: $1959.00 — a round‑number pivot near the 52‑week high zone where rebounds often stall.
- Support: $1441.50 — a nearby floor aligned with a prior buyer‑defense area and sitting not far above the 200‑day trend zone.
