I’ve recently been looking into the robotics sector and realized that we’re at a truly critical turning point. Breakthroughs in AI technology are driving upgrades across the entire industry, but the problem is that there are so many robotics concept stocks—so which one has the highest value? This is actually a good question, because not all robotics stocks are worth paying attention to.

The robotics industry is no longer as simple as industrial applications. From core components and system integration to software development and real-world application scenarios, the whole industry chain has become very complete. But that also means different companies have entirely different moats, and the differences in their real value can be huge.

Let’s first talk about the situation in Taiwan. Delta Electronics is one of the key companies I’m watching. The company has been working in automation for 30 years. With 20 production bases worldwide and thousands of production lines, it’s basically like its own laboratory. Their recent financial results have also been impressive: quarterly net profit hit a new high, and revenue rose nearly 50% year over year, mainly benefiting from AI data centers and the energy transition. More importantly, Delta is transforming into a leading system integrator, and in the second half of 2025 it will also launch new AI server power supply products and liquid-cooling heat dissipation products. A company that has both scale and continuous innovation really does have something.

Chroma is also worth keeping an eye on. Although it doesn’t directly make robots, it makes inspection equipment, which is a must-have in the industry chain. With more than 30 years of measurement experience, gross margin is close to 60%, and revenue growth is over 70% year over year. The faster the robotics industry upgrades, the greater the demand for high-end testing equipment—so Chroma becomes even more attractive.

I’ve also looked into TECO. Their strength lies in motor drive technology, and they are also working on collaborative robots and autonomous mobile robots. Their cooperation with Foxconn will focus on the Taiwan market starting next year. Meanwhile, energy-saving retrofits of electrical and mechanical equipment at old plants will contribute revenue first, and their U.S. data center business is also in the works. Judging by quarterly net profit and gross margin, their profitability structure continues to improve.

Hechaun Technology is also interesting. With over 40 years of experience in automation components, their customers include major manufacturers such as TSMC, UMC, and Foxconn. Recently, they established a robotics business division and launched modularized solutions. Last year, their revenue grew by more than 70% year over year. Management expects that over the next 2 to 3 years they can maintain strong growth, with both full-year revenue and profits achieving double-digit growth.

Chuangbo, a subsidiary under the New Han group, has accumulated more than ten years of experience in robot controllers and is Taiwan’s first company to obtain functional safety certification for robots. Recently, it also partnered with NVIDIA to launch AI modules for humanoid robots. Although the current market is a bit sluggish, the future imagination space for humanoid robots is very large.

We also can’t ignore the U.S. stock market. Palantir and AeroVironment have landed major contracts for autonomous systems in the defense sector, and their stock prices have risen sharply. AMD has also built a complete matrix in high-performance computing hardware—these are all key supports for the robotics industry upgrade.

So how do you select robotics concept stocks? I think there are several angles to consider. First is market demand. Against the backdrop of population aging, demand for surgical robots is growing. The humanoid robot market is expected to exceed $2 billion by 2027, with a compound annual growth rate as high as 154%. So focus on companies that are developing humanoid robot products or planning to enter the humanoid robot industry chain.

Second is technology and R&D investment. The robotics industry iterates extremely fast, and companies that can’t keep up with the pace of innovation are easily weeded out. You can look at the trend in investment cash flow. Over the past 5 years, companies whose CFI has remained at a high level or kept rising usually indicate that they truly place importance on R&D.

Of course, investing in these stocks also involves risks. Rapid technological iteration, changes in the policy environment, and impacts on the labor market all need close attention. In particular, government policy support for the robotics industry varies greatly across countries, so you need to manage your position flexibly.

In summary, the “value” of robotics concept stocks ultimately depends on a company’s technological strength, market adaptability, and long-term growth potential. Companies that have stable cash flow, keep investing in R&D, and also stay aligned with the direction of market demand are usually more worth paying attention to. This sector is indeed full of opportunities, but investors also need to do their homework and have patience to filter for truly promising targets.
