China's Chip Push Shakes Semiconductor Stocks: Valuations and Competitive Pressure

China's rapid advances in semiconductor technology are triggering sharp sell‑offs across global chip equities.

China's Semiconductor Strategy: A New Era in DUV Lithography Production

As China nears serial production of deep‑ultraviolet (DUV) lithography machines, its push to cut external dependence becomes evident. This development signals a strengthening of China's competitive edge in chip‑equipment manufacturing.

Chip Stock Plunge: US and Asian Markets React

■Broadcom shares fell %20.5 over the last five trading days

■Intel shares dropped %18.3

■Micron Technology shares slid %25.4

■Arm Holdings shares declined %20.5

Asian markets mirrored the trend; the KOSPI index fell roughly %21 in the same period. Leading semiconductor firms such as SK Hynix shed %30.9 weekly, while Hanmi Semicon lost %23.

Investor Portfolio Rotation: High Valuations Under Scrutiny

■Double‑digit valuations of AI‑driven chip firms are being questioned for their return speed

■Changxin Memory Technologies (CXMT), a Chinese DRAM player, surged %531.06 on debut, yet sustainability is debated

■Investors shifting from semiconductor stocks to more defensive sectors are a primary driver of the sell‑off

ASML and the Real Impact of DUV Technology

Dutch ASML's DUV equipment remains pivotal for 7 nm chip production. Analysts argue that China's ability to use these machines for 3‑2 nm chips remains limited, implying short‑term competitive gains are modest.

Markets are weighing the long‑term implications of China's chip‑equipment progress while growing doubts over current lofty valuations are fueling volatility in semiconductor equities. Portfolio rotation and shifting competitive dynamics will reshape pricing in the coming quarters.
