Chip Tool Stocks Surge Up to 9% on Samsung, SK Hynix $1.3 Trillion Korea Bet

Shares of U.S. semiconductor equipment companies surged sharply in Tuesday trading following the announcement by Samsung and SK Hynix of a massive $1.3 trillion investment plan to build a chip cluster in South Korea. KLA Corporation (NASDAQ: KLAC) was the biggest gainer, rising 9.28% to $304.23, just shy of its 52-week high of $304.42. Applied Materials (NASDAQ: AMAT) gained 6.02% to $736.46, touching a fresh 52-week high of $739.32 intraday, while Lam Research (NASDAQ: LRCX) rose 5.86% to $435.00.

Potential Drivers

The direct catalyst for the rally is the joint investment plan by Samsung and SK Hynix, the world's two largest memory chipmakers, to create a massive chip production cluster in South Korea. The investment is valued at $1.3 trillion over the coming years, implying huge demand for chipmaking equipment.

Context

The moves come after a period of anticipation in the semiconductor sector, as producers look to boost capacity amid rising demand for chips used in artificial intelligence, electric vehicles, and consumer electronics. ASML Holding (NASDAQ: ASML), the sole supplier of extreme ultraviolet (EUV) lithography machines, is also a key beneficiary, with its shares rising 4.2%.

Similar Sector Moves

Gains were not limited to the three stocks mentioned but extended across the semiconductor equipment sector. Shares of other companies such as Tokyo Electron and Screen Holdings in Japan also rose, reflecting investor optimism that large capital spending by top chipmakers will drive demand for manufacturing equipment.
