ASML's selloff on China's domestic DUV news is an overreaction because the revenue hit is small and China is nowhere on EUV, ASML's real moat. China is making about five DUV machines this year versus the hundreds ASML delivers. BofA, which also calls the selloff an overreaction, estimates China going domestic cuts ASML's sales by about EUR 1.4B next year, or 2.4%, yet the stock fell about 6%. It helps China's chip independence far down the road but leaves ASML oversold today. x.com  x.com 

ASML's 6% drop on a report of Chinese immersion DUV mass production is no cause for panic. Per a Chinese semiconductor expert, the first-gen tool is five or six generations behind ASML's 1980-class machines, which Chinese fabs already stockpile, and SMEE's six dry DUV tools sold in 2023 never ran production. No Western fab is likely to qualify a Huawei-linked tool, the lost revenue was already exiting under export controls, and lithography isn't China's binding constraint. x.com  x.com

The selloff in ASML and BESI on China's new immersion DUV tools is an overreaction with minimal real impact. China plans five units this year and 20 in 2027 for SMIC, Hua Hong and CXMT, under 4% of ASML's roughly 130 annual immersion DUV shipments. DUV can make 7nm chips via multi-patterning, but at higher cost, lower capacity and more alignment errors, and EUV is a fundamentally different technology. Nikon and Canon face the most pressure. x.com 

ASML's fears about Chinese competition are noise: China's claim to compete rests on 20-year-old DUV tools, while nobody else has ASML's EUV machines. ASML is a trillion-dollar monopoly with a 20-year head start, so there is no real competition. The broader tech selloff reflects worries such as Nvidia backstopping OpenAI's buildout and open-weight models like Kimi K3, which are more noise than signal; even good open models need massive infrastructure. x.com 

ASML faces moat erosion now that China has a homegrown alternative to its machines. The Information reports a state-backed Shanghai company has started mass-producing DUV lithography tools. Chinese fabs stockpiling older DUV tools had become a major revenue driver, with China at 36% of sales in 2024 and 29% last year. Output is tiny, about five machines this year and maybe twenty next. But once a second supplier exists, the question shifts from "no alternative" to "for how long." x.com 

ASML's reported inability to make enough machines for the next two years is a buy signal for the whole AI stack. Its stock still sold off despite that shortage. x.com 

ASML's selloff on China's mass production of DUV machines is a huge overreaction that double counts ASML's own guidance. Export controls made Chinese indigenization inevitable, with SMIC trialling domestic tools since Q3'25, and ASML's China share of sales was already falling from ~50% in 2024 to 33% in 2025 and ~20% guided for 2026. ASML is richly valued, but the stock held up after earnings that showed the same China decline. x.com  x.com  x.com 

ASML may have topped, since semicap thrives on shortage and would be hit hardest in an overbuild. Then earnings acceleration from memory and fab projects stops or reverses; the labs' leading-edge chase may be at its apex, positioning is bullish and the moat is threatened. Bullishness on Korean, US and Taiwan fab projects makes sense for now. But if the cycle top is confirmed and labs change how they chase the frontier, or token deflation kills some labs, the shortage can end sooner. x.com  x.com  … Show more

ASML's EUV R&D is starting to pay off through operating leverage. Q3 R&D fell as a share of sales, though one quarter is not a trend. Higher units, IBM sales and EUV/DUV prices put 2028 estimates well above the 2030 guide and ahead of consensus; shares look cheap at €1,530. Assuming 30% prepayment, liabilities imply €42-45bn of orders in 2026's first nine months, subject to invoicing lags. The proposed MATCH Act could restrict China sales; 2029-30 demand is less certain than 2028. x.com  x.com  … Show more
