Huayan Robotics (01021.HK) saw its stock price plummet 6.73% during intraday trading on Monday.

The sharp decline is attributed to two key structural factors. First, the joint global coordinator partially exercised the over-allotment option, involving approximately 13.469 million H shares. This increased the supply of tradable shares, raising immediate investor concerns over equity dilution. Second, the stabilization period associated with the company's global offering concluded recently, removing an artificial price support mechanism that had been in place.

Market analysis suggests the combination of these events created significant short-term selling pressure. Although the company has recently launched its new Echo and HY series seven-axis humanoid robotic arms for pre-order, this positive development was insufficient to offset the downward pressure from the increased share supply and the end of price stabilization activities.
