The AI investment boom spreads upstream, with several leading US semiconductor equipment companies doubling in value this year

According to statistics, all nine semiconductor equipment companies with a total U.S. stock market capitalization exceeding 10 billion USD have seen their stock prices increase by over 75% since the beginning of this year. Among them, seven stocks—Applied Materials, Lam Research, KLA Corporation, Teradyne, MKS Inc, Entegris, and Onto Innovation Inc—have doubled in price within the year. In terms of industry logic, various signs indicate that semiconductor equipment is ushering in what institutions refer to as a “seller’s market.”
