Sanhua Intelligent Controls (2050.HK) climbed more than 3% in Hong Kong trading to HK$27.900, reaching a one-month high for the stock.

Shares of the thermal-management components maker rallied after the company disclosed a series of positive developments, including steady progress in its liquid-cooling business and board approval for an A-share buyback program valued at 200 million to 400 million yuan. The stock also drew a bid from a broader rally in robotics plays, as BYD's humanoid robot is slated for an August launch.

Institutional investors including Schroders and Baillie Gifford have continued to build positions in recent weeks, signaling sustained foreign confidence in Sanhua's long-term prospects.
