Shares of Chinese electric-vehicle maker Xpeng Inc. jumped more than 10% in early U.S. trading on Thursday, extending to roughly 12% as the session progressed. The rally follows the company’s release of quarterly results earlier this week that exceeded market expectations, prompting renewed buying interest in the stock. Peer NIO Inc. also advanced sharply, gaining about 11% and reaching an intraday high of $5.68, which values the company at close to $13 billion. Investors rotated into the stock ahead of NIO’s second-quarter earnings report due on 2 September, despite analyst forecasts of a sizeable loss. The moves underscore renewed enthusiasm for U.S.-listed Chinese EV manufacturers, a sector that has been volatile amid shifting sentiment on growth prospects and competitive pressures in the domestic market.
