On the 1st, the first trading day of June, robot stocks showed a strong performance simultaneously in the domestic stock market, emerging as a key theme driven by expectations for the expansion of the artificial intelligence (AI) industry and the growth of the humanoid robot market. Investors' funds flooded into robot-related stocks en masse, demonstrating a collective surge.

The most notable stock was Robostar. During the morning session that day, Robostar hit the daily price limit, recording the maximum allowable gain. The stock price surged by 30% in a single day, climbing to 122,200 won. Doosan Robotics, considered a leading domestic humanoid robot stock, also surged 23.85% to 131,900 won, drawing market attention. In particular, Doosan Robotics saw a massive influx of buying, with its trading volume exceeding 8 million shares.

Robotis, another leading humanoid stock, rose 18.74% to 386,500 won, while Rainbow Robotics gained 10.40% to 775,000 won, attracting the interest of institutional and individual investors. Hulim Robot also rode the upward trend.

Robot parts stocks also showed strength, including SPG, a core company in the precision reducer sector, and Heizen R&M, which benefited from expectations of expanding demand for robot motors. Trading value was also concentrated in robot stocks. Hyundai Movex traded over 7 million shares in active trading, and Hulim Robot and Doosan Robotics also recorded high volumes. The top 10 most-watched robot stocks in the market that day were tallied as △ Robostar △ Doosan Robotics △ Robotis △ Haesung Aerobotics △ Angel Robotics △ Rainbow Robotics △ Roborobo △ Heizen R&M △ TPC Robotics △ SPG.

The market is noting that the global AI industry has recently been expanding beyond the simple software stage into the market for robots that move in actual industrial settings. In particular, as global big tech companies, including Nvidia, designate 'Physical AI'—which combines the judgment capabilities of generative AI and humanoid robots with actual robot movements—as a future core industry, a re-evaluation of related companies is continuously taking place.

The securities industry analyzes that expectations for the mid- to long-term growth of the robot industry are growing as the simultaneous progression of AI industry growth and the expansion of global manufacturing automation unfolds. However, there are also opinions that the possibility of widened volatility should be kept in check, as stocks making short-term surges have recently increased. Moving forward, the expansion of robot investments by global AI companies and the technological development achievements of domestic companies are expected to act as key variables determining the trend of robot stocks.
