Horizon Robotics-W experienced a significant intraday surge, with its stock price soaring 5.14% during Tuesday's trading session.

The sharp upward movement appears driven by the company's recent technological advancement and shareholder-friendly capital allocation. Horizon Robotics-W officially released and open-sourced its HoloMotion-1 model, a 400-million-parameter cerebellum large model designed for full-body control of humanoid robots, which is capable of high-speed real-time inference on-device.

Further bolstering investor sentiment are the company's substantial share repurchase activities, having bought back over HK$270 million worth of shares recently, alongside a proposed authorization to repurchase up to 10% of its issued share capital. Market analysts also point to potential short-covering activity as the stock recovers from near 52-week lows, creating a confluence of positive factors.
