国泰海通｜机械：关注华为开发者大会，工程机械板块周期性回升

Group 1 - The mechanical equipment index experienced a decline of -0.67% during the week of June 9 to June 13, 2025, with a focus on technological innovation in humanoid robots, recovery in domestic engineering machinery sales, and strengthened demand for semiconductor equipment autonomy [1] - In the robotics sector, a cautious short-term outlook is advised, while a strong long-term optimism is maintained, as the current valuation increase is perceived to be outpacing actual industry progress [1] - The engineering machinery sector shows a cyclical recovery trend, with significant long-term investment value. In May 2025, the average working hours for major products was 84.5 hours (down 3.86% year-on-year, down 6.25% month-on-month), and excavator sales reached 18,202 units (up 2.12% year-on-year), with cumulative sales from January to May at 101,716 units (up 17.4% year-on-year) [1] Group 2 - In the low-altitude economy, accelerated industrial collaboration is expected to benefit the power system sector, enhancing core technology development and industrialization processes through deeper cooperation with eVTOL manufacturers [2] - In the controlled nuclear fusion sector, intensive bidding for fusion reactor components is anticipated to accelerate benefits for power supply and detection systems, supported by increased policy backing and technological breakthroughs [2] - In the export chain, consumer-grade export equipment companies with high demand certainty and low technical dependency are expected to benefit first from the backdrop of fluctuating trade tensions, with short-term order recovery and valuation boosts [2]
