Qualtec Co.,Ltd. <9165> surged on heavy volume. The stock jumped more than 21% at one point to hit 1,959 yen, marking its first year-to-date high in about three months. Its market capitalization reached the highest level since late February 2024. The stock is now entering a zone of thin historical trading volume, paving the way for potentially lighter price action.

Qualtec derives its core revenue from the reliability evaluation of semiconductors and electronic devices, while also engaging in laser micro-processing for semiconductor packages and substrates. Amid surging global demand for new AI data centers, the need for highly efficient next-generation power semiconductors is growing. The company is well-positioned to capture reliability evaluation demand for these power devices. Expectations are also rising for its laser processing capabilities, a key technology in optical-electrical convergence. With a market capitalization of under 5 billion yen, the small-cap stock shows no signs of overvaluation based on metrics like the price-to-earnings (PE) ratio, fueling market views of significant room for an upward valuation adjustment.
