Apple Stock Drop Puts 3 Taiwan Chip Stocks On Retail Investors’ Radar

Simply Wall St·07/31/2026 05:16:59
Listen to the news

Apple’s latest results have put a spotlight on the plumbing of the digital world, the semiconductor and memory chip manufacturers that sit behind every device and data center. The company beat analyst expectations on revenue and net income, yet its warning about supply chain strain, memory chip shortages and sharply higher chip prices has already hit Apple stock, which fell over 6% after hours. For investors, this kind of shock can reprice both risks and potential rewards. This article looks at 3 stocks from our Semiconductor and Memory Chip Manufacturers screener that are directly exposed to this news.

Silergy (TWSE:6415)

Overview: Silergy is a power management and mixed signal chip designer that supplies a wide range of integrated circuits used in everything from data centers and communication equipment to electric vehicles, factory automation and consumer electronics. The company focuses on DC and AC power regulators, battery management, sensors and embedded processors that help its customers manage energy use and system performance inside their hardware.

Operations: Silergy generates all of its reported revenue, about NT$19.6b, from semiconductor products.

Market Cap: NT$145.8b

Silergy stands out in the current AI driven chip squeeze because it sits at the intersection of power management and high performance compute, areas that are central to data centers and advanced devices. Over the past year, its earnings growth outpaced the broader semiconductor industry, and analysts expect both earnings and revenue to grow faster than the Taiwan market. At the same time, the share price still screens as below some estimates of fair value. That mix of growth and valuation comes with trade offs. The P/E is high, the balance sheet leans on external borrowings, and the board is relatively young in tenure. For investors willing to weigh those factors carefully, the combination of AI related demand and improving profitability may justify further research.

Silergy’s earnings and revenue are set against a share price that still screens as below some estimates of fair value, which raises a bigger question about what the market might be missing in the DCF valuation analysis for Silergy

Visual Photonics Epitaxy (TWSE:2455)

Overview: Visual Photonics Epitaxy is a Taiwan based specialist in epitaxial wafers, supplying advanced microelectronics and optoelectronics layers such as GaAs and InP wafers used in high frequency chips, optical communication, sensors and power devices for global semiconductor customers.

Operations: Visual Photonics Epitaxy reports NT$3,545.79m in revenue from semiconductor equipment and services, with sales split across Taiwan, the United States, Mainland China and other regions.

Market Cap: NT$49.1b

Visual Photonics Epitaxy sits in a part of the chip supply chain that can directly feed into the kind of high performance computing and memory rich systems now straining Apple’s suppliers. Forecast earnings growth above 40% a year and revenue growth above 30% have caught investor attention, and the recent quarter showed higher revenue and net income even as margins softened. That growth profile comes with a high P/E and a share price that screens above some cash flow estimates. There is added concern from funding that relies on external borrowing and a volatile share price. For investors who can accept those trade offs, the mix of high growth forecasts, selected earnings quality indicators and exposure to AI related demand may justify a closer look.

Visual Photonics Epitaxy’s rapid revenue and earnings forecasts suggest an accelerating story that many investors may be glossing over. See how the analyst forecasts for Visual Photonics Epitaxy ties that optimism to a crucial funding and volatility twist.

Alchip Technologies (TWSE:3661)

Overview: Alchip Technologies designs and manufactures custom application specific integrated circuits and system on a chip solutions that sit at the heart of AI accelerators, high performance computing, networking gear and advanced electronics. The company provides chip design, packaging, testing and IP integration services that help large customers turn complex chip ideas into production ready silicon.

Operations: Alchip Technologies generates NT$24.6b in revenue entirely from semiconductors, with customers spread across the United States, China, Japan, Europe and other regions.

Market Cap: NT$227.1b

Alchip Technologies sits squarely in the AI and high performance computing build out that is now straining Apple’s chip supply chain, with NT$24.6b of semiconductor revenue and a customer base that includes North American hyperscalers. Forecast revenue growth of 52.2% a year and earnings growth of 39.8% a year, together with a recent step up in net margins to 22.6%, indicate why expectations are high even after a period when the share price lagged the wider Taiwan semiconductor sector and traded on a rich P/E. Funding relies fully on external borrowing and revenue is concentrated in a handful of large customers, so execution and customer stickiness matter. The question is whether that AI project pipeline can carry enough weight to justify those expectations and recent equity raising.

Alchip Technologies’ AI pipeline, NT$24.6b in revenue and global customer mix hint at a story the market may not fully appreciate yet. See how the analyst forecasts for Alchip Technologies connects that excitement to one critical pressure point
