XPeng Inc. (09868.HK) saw its stock price surge by 9.57% in pre-market trading on Tuesday, continuing the positive momentum from its impressive performance in the U.S. market. The Chinese electric vehicle maker's shares had previously soared 16.24% in the United States, signaling strong investor confidence in the company.

The substantial gain in Hong Kong appears to be driven by multiple factors. Firstly, the stock's robust performance in the U.S. market likely contributed to positive sentiment among Hong Kong investors. Additionally, data from the Stock Connect program revealed an increase in mainland Chinese investor holdings of XPeng shares, with the shareholding ratio rising by 0.73% to 18.95%. This uptick in mainland interest suggests growing optimism about XPeng's prospects among Chinese investors.

While specific company news driving the stock's rally was not immediately apparent, the broader market context may have played a role. U.S. stocks closed higher on the previous trading day, led by tech shares, amid growing optimism over a potential end to the U.S. government shutdown. This positive sentiment in the tech sector could have spilled over to electric vehicle stocks like XPeng. Investors will be watching closely to see if XPeng can maintain this momentum and translate it into sustained growth and improved financial performance in the competitive EV market.
