Summary

Green Harmonic, also referred to as Leaderdrive and the A-share company 绿的谐波, rose 20.00% to its daily limit at 393 yuan on June 5 after Serenity publicly endorsed the stock as a favored China-listed humanoid robotics play. Serenity said the company holds more than 60% of China’s harmonic reducer market and put its market value at about 57.73 billion yuan. Trading turnover reached CNY 7.929 billion, the turnover rate was 12.22%, and after-hours disclosures showed the Chaogu Yangjia trading seat recorded net buying of CNY 111 million. The move came amid a public dispute between Serenity and market commentator Garrett Jin over the timing of investing in China’s humanoid robot sector, while Nvidia CEO Jensen Huang’s comments in South Korea that robotics could become Korea’s next major industry added to broader investor interest.
