Its Leading Edge Advanced Packaging (LEAP) services have become a central growth driver as demand for AI and high-performance computing chips accelerates. Investors closely follow ASX because it sits at a critical point in the AI semiconductor supply chain, converting advanced silicon into packaged, tested, ready-to-deploy components.

ASE Technology Holding (ASX) Stock Price Performance: Last 30 Days vs. Quarter

Over the last 30 days, ASX advanced approximately 20.4%, rising from a closing price of $39.47 to $47.53. The gain was broad-based but accelerated in the back half of the period, with the shares breaking decisively through the low-$40s before finishing near recent highs.

Over the last quarter, the stock is also higher, up roughly 17% from about $40.56 in mid-July. That headline move, however, masks significant intra-quarter volatility: shares pulled back into the low $30s in late July before staging a steady, multi-week recovery as demand visibility and profitability momentum improved. The overall three-month trend is firmly upward, with higher lows and renewed buying interest in the advanced-packaging theme.

What Drove ASX Stock Price in the Last 30 Days

The recent rally reflects continued strength in AI and high-performance computing demand, which is flowing directly into ASE Technology's advanced packaging and testing business. Investor sentiment was reinforced by strong fundamental momentum: in the second quarter of 2026, the company reported record ATM revenue of TWD 126.1 billion, up 36% year over year, while ATM gross margin expanded to 27.3%.

A higher mix of LEAP services has been the primary profitability lever. Management raised its 2026 LEAP revenue outlook and increased its 2026 capital expenditure plan by about $2 billion to roughly $10.5 billion, with a substantial share directed toward leading-edge capacity. This commitment to expanding high-value packaging and testing capacity signaled confidence in sustained AI-driven demand.

Analyst activity also contributed to the move. Earnings estimates for the company have been revised higher, and the stock has carried a Zacks Rank #1 (Strong Buy), reflecting improving earnings visibility. Broader sector rotation into AI-enabling semiconductor suppliers added further support.

What Drove ASX Stock Performance Over the Last Quarter

The quarterly trend reflects a larger narrative: ASE Technology is benefiting from a structural shift toward advanced packaging as chipmakers pursue more complex, power-hungry designs. Over the past three months, LEAP demand strengthened, ATM profitability improved, and management guided for sequential growth with gross margin expected to reach 28% to 29% in the third quarter.

The period was not without turbulence. A sharp pullback in late July briefly took shares into the low $30s before buyers returned. That recovery was supported by consistent execution, rising factory utilization, and a richer product mix, with ATM growing its share of consolidated revenue and operating profit. Compared with peers such as Amkor Technology (AMKR) and Intel (INTC), ASE's margin expansion and AI-packaging exposure have helped sustain investor interest through the quarter's volatility.

ASX Stock Forecast Drivers: What Investors Should Watch Next

Looking ahead, investors should monitor the company's third-quarter results, including whether ATM revenue growth and gross margin meet management's guidance of an 11% to 13% sequential increase and a 28% to 29% margin. The pace of LEAP capacity installation and associated depreciation costs will be important, as management expects much of the new capacity to begin contributing meaningfully from the fourth quarter of 2026.

Broader themes also matter: the trajectory of AI and data-center capital spending, competitive dynamics in advanced packaging, and macroeconomic conditions affecting semiconductor demand. Valuation remains a consideration, as the stock trades at a premium forward multiple following its strong run. These factors, rather than any single event, will likely shape the next phase of the stock's performance.
