  "account": "Advantest's stock price jumped 9.5% to ¥34,030 on Tuesday following AI company Anthropic's filing of its IPO prospectus with U.S. securities regulators. The news revealed a staggering 100-fold increase in revenue over just two years, which significantly alleviated investor concerns about the commercial viability of AI investments. This positive sentiment triggered a broad rally in semiconductor-linked equities worldwide, with a 2.8% increase in the Philadelphia Semiconductor Index playing a crucial role. Advantest had been among the hardest-hit stocks during a three-day selloff earlier in the week, losing over 420 points on the Nikkei 225 alone. The stock was technically oversold, making it primed for a rebound once investor sentiment improved. Moreover, Advantest's own second-quarter fiscal 2026 results are set to be released on October 28, with strong growth in revenue and operating profit from the previous quarter fueling expectations of continued success. The Nikkei 225 rose approximately 1.9% on the day as semiconductor and AI-related stocks led a broader market recovery. The global picture was similarly optimistic, with South Korea's KOSPI surging more than 4% as chip giants rebounded sharply as well.",
