NIO-SW (09866) shares experienced a significant surge during Wednesday's trading session, soaring by 8.52% and reaching a new high since October last year. The stock climbed to HK$55.45 at its peak, with strong trading volume indicating renewed investor interest in the electric vehicle maker.

The impressive rally can be attributed to several factors, chief among them being the upcoming NIO Day 2025 event scheduled for September 20. At this event, the company is set to officially launch its new ES8 model, generating anticipation among investors and consumers alike. This launch is part of NIO's broader multi-brand strategy, which Guotai Securities believes is entering a "harvest period."

Guotai Securities expressed optimism about NIO's prospects, citing the company's comprehensive price coverage ranging from 150,000 to 800,000 yuan across its three major brands. The brokerage highlighted the strong initial performance of NIO's new models, with the ONVO L90 securing over 10,000 orders on its first day and the new ES8 reportedly outperforming it. Analysts are particularly bullish on NIO's outlook for 2025, expecting benefits from the new product cycle, advancements in intelligent features and battery swapping technology, and improvements in cost reduction and efficiency. This positive sentiment from analysts appears to be a key driver behind today's stock surge, as investors position themselves ahead of potential growth.
