Recently, I’ve been looking into the robotics concept stocks sector and found some quite interesting investment logic.

Honestly, the robotics industry is currently at a very critical moment. With breakthroughs in AI technology, listed companies in this field are迎來 unprecedented development opportunities. But the question is, among these robotics concept stocks, which ones are truly valuable? Which ones are worth paying attention to? I recently did some in-depth research and found that some companies’ layouts are indeed different.

First, let’s talk about Quanta (2382). This company is not just involved in server OEM manufacturing. Its subsidiary, Daming Robotics, is the highlight—independently developing AI vision and collaborative arm technologies, supported by Quanta’s strong server computing power. This integration of software and hardware, from cloud training to edge execution, has competitiveness in the era of physical AI. Daming is pursuing a “wheel-type humanoid robot” route, which better meets factory demands for stability and high load capacity, allowing it to penetrate semiconductor, electronics, and automotive production lines more quickly. In the first quarter, revenue reached 809.2B NT dollars, a 66.6% YoY increase, setting a new quarterly high, with over 75% of that from AI servers. Although gross margin dropped to 4.78%, the company believes that operational leverage will improve profitability after the second quarter. While robot business revenue is still single-digit, its gross margin is significantly higher than OEM levels, making it a key part of the group’s transformation.

Advantech (2395) has also made solid progress in its transformation over the past few years. Its goal this year is to increase edge AI revenue share to 30%, with first-quarter edge AI revenue growing at a 67% YoY rate. Advantech’s strength is not just providing computing platforms but also integrating sensors, AI software stacks, and industrial-grade certifications into ready-to-use robot solutions. This fills a “integration gap” in the market, with high customer stickiness in autonomous mobile robots, humanoid robots, and medical collaborative robots. Plus, its deep ties with global computing giants like NVIDIA, combined with decades of industrial application experience, enable it to convert cutting-edge chip technology into solutions suitable for factories, hospitals, and retail environments—something many competitors cannot do. Orders shipped have maintained a long-term ratio above 1.5, providing high visibility.

Sung Hung (2049) is also actively extending into high-end robotics. In the first quarter, robot-related revenue already exceeded 12%, with a growth rate of over 40%. The company has deep cooperation with US-based AI logistics robot developer Dexterity, and shipments of humanoid and AI logistics robots are expected to increase quarter by quarter. First-quarter EPS reached 1.64 NT dollars, a six-quarter high, with gross margin continuing to challenge the 30%+ target. As one of the top three global ball screw manufacturers, its layout in harmonic reducers and joint modules has also gained recognition from international AI and humanoid robot giants. However, it’s worth noting that Sung Hung’s current stock price is relatively high and volatile, so risk management is essential.

Dah Yin Micro Systems (4576) has core competitiveness rooted in its high-precision air bearing positioning platforms, which are key components in advanced semiconductor packaging and 2nm process equipment. As demand for AI chips explodes, wafer fabs are demanding higher process miniaturization and packaging accuracy, establishing a solid technological moat for Dah Yin Micro. Its 2026 layout in the robot market is also entering a harvesting phase, with new driver product lines already shipping in large quantities. In the first four months, cumulative revenue increased by 43.95% YoY, with first-quarter consolidated revenue up 45% YoY, maintaining a gross margin of 39%. The company plans to add 30% capacity in the second half to handle orders, with visibility extending into Q4.

Solomon (2359) mainly provides software solutions, covering 3D vision, defect detection, and robot control. Through collaborations with NVIDIA Omniverse platform and Project GR00T humanoid robot foundational models, it can significantly shorten robot development cycles. First-quarter EPS was 0.78 NT dollars, a 1,014% YoY increase, with AI vision business already contributing tangible profits. However, Solomon’s stock price is much more volatile than large-cap stocks, making it more suitable for swing trading, but strict stop-loss discipline is necessary.

Regarding US-listed robotics concept stocks, industrial automation giants like Rockwell Automation and Teradyne, which are profitable and have clear application scenarios, perform relatively strongly. Startups like Symbotic and Intuitive Surgical tend to be more volatile.

When selecting robotics concept stocks, I think there are three key aspects to consider. First is market demand— the broader the application of robot technology, the greater the growth potential for companies. For example, TrendForce estimates that by 2027, the global humanoid robot market could surpass $2 billion, with a compound annual growth rate of 154% from 2024 to 2027. Focus on companies developing humanoid robots or planning to enter the humanoid robot industry chain. Second is R&D investment—robot industry technology evolves rapidly, and companies that cannot maintain a high pace of innovation risk being eliminated. Pay attention to whether companies allocate sufficient cash flow to R&D; those emphasizing technological innovation are more likely to deliver long-term returns.

Investing in robotics concept stocks offers the benefit of aligning with future technological development directions, with huge growth potential. But there are also risks—robot technology evolves quickly, especially when combined with AI, requiring close attention to a company’s R&D capabilities and market adaptability. Government policies supporting the robotics industry vary across countries and can influence company development. The rapid adoption of robot technology will impact labor markets worldwide, so investors need to stay alert to regulatory changes and manage their positions flexibly and promptly.
