ASX · Analysis updated Nov 10, 2026, 6:00 PM ET
Why is ASE Technology Holding Co., Ltd. (ASX) stock moving?
ASE's fundamentals remain strong. Q3 net revenues rose 44.8% YoY to NT$244,161M, EPS beat estimates, and gross margin widened to 22.1%. October revenue rose 40.4% YoY to US$2.78B, and the company is expanding capacity with a raised US$11.5B capex budget and a steady flow of equipment and facility contracts (NT$531M, NT$590M, NT$2.03B, NT$4.97B). The stock is more volatile than the news flow. It peaked at 44.73 on Oct 29, fell about 20% after Q3 results, then dropped 20.8% on Nov 5 to 29.72 on roughly double typical volume, after the capex increase was announced on Nov 3. The provided news does not identify a cause for the Nov 5 move, so that link is unconfirmed. The shares have since recovered to 35.48 (+3.3% on Nov 10) but remain about 20% below the Oct 29 close of 44.55. Near term, the outlook is balanced: the rebound and strong monthly revenue offset uncertainty about the drop. Over one to six months, the growth, capex and contract flow favor the company, though heavy spending and cyclical chip demand are risks.

About ASE Technology Holding Co., Ltd.
ASE Technology Holding is a Taiwan-based company and the world's largest outsourced semiconductor assembly and test (OSAT) provider: it packages and tests chips designed or made by other companies, and it also builds electronic modules and systems through its USI subsidiary. What sets it apart right now is its fast-growing leading-edge advanced packaging and testing business (which it calls LEAP) for AI chips, which it expects to bring in more than about $4 billion of revenue in 2026.
How it makes money
Most of its revenue comes from two parts. The first is assembly, testing and materials (ATM): fees for packaging chips, including wire-bond, flip-chip and advanced packaging, and for testing them. ATM is the larger and more profitable part, and its revenue grew about 35% year over year in the first half of 2026. The second is electronic manufacturing services (EMS) through USI, which builds modules and systems for electronics brands at lower margins. Second-quarter 2026 revenue was about NT$191 billion (roughly US$6 billion), with a gross margin of about 21%. Each US-listed ADR represents ordinary shares that also trade in Taiwan under the code 3711.
