On October 2, ASML Holding NV rose 3.08% in regular trading, trading at $1,866.31 per share, with turnover of $467 million. The gain came amid a broad rally across the semiconductor equipment sector, fueled by multiple converging catalysts.

On the news front, NVIDIA announced a $150 billion increase to its stock buyback authorization, while AMD committed $8.2 billion to acquire World Labs to advance AI world models, significantly boosting market confidence in AI compute investment. Citi analysts named ASML as one of the biggest beneficiaries of the ongoing AI chip and memory chip capacity expansion trend. Additionally, ASML recently secured adoption commitments from both TSMC and Samsung for its next-generation High NA EUV lithography systems, with order visibility now extending into 2028. UBS analysts noted that ASML's lithography output forecasts still have room for upward revision, with plans to raise DUV and EUV production by 30% in 2027 and another 30% in 2028. Barclays also pushed back on recent bearish sentiment, arguing that the sector pullback reflects normal momentum adjustment rather than fundamental deterioration.

Within the Semiconductor Equipment sector, peers also posted strong gains: Lam Research up 3.44%, Applied Materials up 3.10%, KLA Corporation up 3.39%, Teradyne up 4.98%, and AXT Inc up 0.16%.
