Advantest, Applied Materials, Tokyo Electron flagged as AI-chip plays

The article is framed around a shift in market mood: after the US and China showed willingness to cut tariffs and extend their trade truce, investors have begun to price in a world that is "not the worst-case scenario." Simply Wall St's screener for AI-infrastructure and semiconductor enablers produced 51 candidates in total, of which three are profiled here.

Advantest supplies automated test equipment used to verify advanced semiconductors and electronic components before mass production, with most revenue coming from its test systems business. Applied Materials sells manufacturing equipment and materials-engineering solutions to fabs making advanced AI chips, and Tokyo Electron supplies the tools needed for AI GPUs and high-performance memory. Because each sits at a different point in the chipmaking chain — testing, deposition and materials, and fab equipment — the same AI capex cycle reaches them through different order books.

The common thread is dependence on assumptions that could break either way. Advantest's case rests on capacity expansion not overshooting demand; Applied Materials' rests on structural AI and high-performance computing growth driving investment in gate-all-around transistors, high-bandwidth memory, and advanced packaging; Tokyo Electron's rests on supply-chain regionalization translating into years of new fab construction. For investors weighing these names, the key question may be whether those premises hold together or diverge.
