I’ve recently been keeping an eye on the trends in humanoid robot concept stocks and found that this sector is truly standing at a crucial turning point. Breakthroughs in AI are heating up the entire robotics industry chain, but if you want to know who has the highest value, you really need to dig deeper.

First, let’s talk about Quanta. This company isn’t just a server contract manufacturer. Its subsidiary, Daming Robotics, is pursuing a wheeled-humanoid-robot route. Combined with its own AI vision and collaborative arm technology, plus Quanta’s strong server computing horsepower, this end-to-end integration capability of software and hardware does give it an advantage in the era of real-world AI. First-quarter revenue was 809.2 billion yuan, up 66.6% year over year and hitting a new high. However, its gross margin fell to 4.78%, mainly because the shipment mix of high-priced AI server rack cabinets increased. Although the robotics business still accounts for only single-digit revenue share, its gross margin is clearly higher than contract-manufacturing levels—this is the key to the group’s transformation. The P/E ratio is about 13x, and on the capital side, foreign institutional buying has clearly warmed up in late May.

Advantech is taking an edge AI route. This year, its goal is to raise edge AI revenue share to 30%. In the first quarter, edge AI revenue grew 67% year over year, indicating that its technology roadmap is already beginning to pay off. What makes it strong is not only providing computing platforms, but more importantly integrating everything—sensor connectivity, AI software stacking, and industrial-grade certifications—into a ready-to-use robot solution, which precisely fills the market’s integration gap. With a deep tie to NVIDIA and decades of industrial application experience, it can turn cutting-edge chip technology into industry-ready solutions truly suitable for factories and hospitals. The order-to-shipment ratio has long been maintained above 1.5, orders have high visibility, and as the share of software solution offerings rises, profitability quality continues to improve.

Sung-Eel (Sung Hung) has extended from traditional machine tools into high-end robots. In the first quarter, the share of robot-related revenue exceeded 12%, with a year-on-year growth rate of over 40%. It has deep cooperation with U.S. AI logistics robot developers, and subsequent contributions from humanoid robots and AI logistics robots to shipments are expected to increase quarter by quarter. In the first quarter, EPS reached 1.64 yuan, a new high in nearly six quarters. Product prices were raised by 7% to 15%, and the gross margin is currently targeting over 30%—it’s right on the edge. As one of the global top three ball screw manufacturers, its layout in harmonic reducer and joint module also has gained favor from international AI giants. However, the stock price is relatively high, so risk control needs to be in place.

DAE HIN Micro Systems’ air-bearing positioning platform is a key component used in advanced semiconductor packaging and 2-nanometer process equipment. In 2026, the robot market’s layout will enter a harvest period, and its new drive unit product line has been shipped in large quantities. Over the first four months, cumulative revenue growth was 43.95% year over year. First-quarter consolidated revenue increased 45% year over year, and gross margin remained at a high level of 39%. In the second half of the year, it plans to add 30% capacity. Order visibility has already reached the fourth quarter, and market estimates suggest 2026 EPS may land in the range of 3.7 to 4.8 yuan.

Solomon focuses on software solutions, with technology covering 3D vision, defect detection, and robot control. Its collaboration with the NVIDIA Omniverse platform can significantly shorten the robot development cycle. First-quarter EPS was 0.78 yuan, a year-on-year increase of as much as 1,014%. The AI vision business has already started contributing tangible profits. However, the stock price has high volatility, so it’s more suitable for swing trading—strict stop-loss discipline is essential.

In the U.S. market, industrial automation leaders such as Rockwell Automation and Teradyne—companies with solid profitability and clear application scenarios—are relatively strong performers. Startups like Symbotic and Intuitive Surgical tend to be more volatile.

When picking humanoid robot concept stocks, you can look at a few directions. First is market demand. TrendForce estimates that by 2027, the global humanoid robot market value could exceed 2 billion US dollars, and the compound annual growth rate from 2024 to 2027 could reach 154%. So, focus on companies that develop humanoid robot products or move into the industrial chain. Second is R&D investment. Since iteration speed in this industry is very fast, you should check whether the company allocates sufficient cash flow to its R&D department. Third, pay attention to changes in investment cash flow. Companies that have kept CFI at a high level or have kept pushing it higher over the past 5 years are worth watching.

The benefit of investing in robot concept stocks is participating in the high-growth opportunities brought by future technological progress, but risks are also not small. In the AI era, robot technology evolves extremely quickly, so you need to closely monitor each company’s R&D capabilities and market adaptability. Differences in government policies across countries will also affect company development. In addition, the widespread adoption of robot technology will impact the labor market, so investors should control their positions in a timely and flexible manner.
