Hesai-W (02525) experienced a significant price surge intraday, with shares soaring 8.70% on Thursday. The dramatic upward movement came as the stock opened for trading, indicating strong investor interest from the market open.

The sharp increase appears to be driven by news that Hesai-W has been added to the list of securities eligible for the Hong Kong Stock Connect program. This inclusion, which takes effect immediately, allows mainland Chinese investors to purchase the stock through the trading link, potentially expanding the investor base and increasing liquidity for Hesai-W shares.

Analysts note that inclusion in the Stock Connect program typically generates positive sentiment as it enhances accessibility for a large pool of mainland capital. The timing of the announcement just before market open likely contributed to the immediate price reaction as traders positioned for increased demand from new investor segments.
