Hesai-W (02525) opened more than 7% higher, with its stock price rising 7.49% to HK$215.2 by the time of reporting. The trading volume reached HK$8.06 million. The increase follows the announcement from global index provider MSCI regarding its quarterly index review for February 2026, which will take effect after the market close on February 27. The MSCI China Index will add 37 constituents and remove 16. Hesai is among the newly included companies. A research report from CLSA noted that Hesai Group became the world's largest lidar supplier by revenue in 2024, with monthly production capacity and deliveries both exceeding 200,000 units. As lidar increasingly becomes a standard safety feature in smart vehicles and multi-lidar solutions gain traction in assisted and autonomous driving markets, the brokerage expects Hesai to benefit significantly from the growing adoption of lidar, thanks to its industry leadership and large-scale manufacturing capabilities.
