Advantest is a leading semiconductor test company, with about 66% share in SoC testers, a 44.2% FY2025 operating margin, and about JPY 319.8 billion in net cash, making it a high-quality business. Yet at JPY 27,660, the stock trades at roughly 50x P/E and about 67x conservative owner earnings, already above the upper end of the optimistic DCF range, leaving insufficient margin of safety. Research rating Watch: the core risk is that strong AI demand and elevated margins normalize while the valuation multiple compresses.
