ASE Technology Holding is sharply higher after the market refocused on its latest monthly sales update showing a strong March finish and solid year-over-year Q1 growth. The company reported unaudited March 2026 consolidated net revenues of NT$61,577 million (US$1,949 million), up 18.2% sequentially and 14.6% year over year, and unaudited Q1 2026 consolidated net revenues of NT$173,662 million (US$5,508 million), up 17.2% year over year.

The print reinforces expectations that demand tied to AI-driven semiconductor complexity is supporting outsourced packaging and testing volumes, particularly in higher-value advanced packaging and test flows. With investors positioning ahead of the company’s next quarterly report, the March acceleration is being treated as a confidence boost that near-term fundamentals remain constructive.

The move is also being amplified by a risk-on bid in semiconductor stocks, which tends to lift supply-chain names alongside major chipmakers. In that setting, a fresh, company-specific datapoint like a strong monthly revenue release can act as a catalyst and concentrate buying into names seen as direct beneficiaries of advanced packaging and testing demand.
