Chinese EV Stocks Decline as Tesla’s Weak Q3 Results and Rising Costs Weigh on Sector

Chinese electric vehicle (EV) stocks slipped on Thursday, mirroring losses in Tesla Inc (NASDAQ:TSLA) after the U.S. automaker posted disappointing third-quarter earnings and warned of significantly higher expenses in the coming year.

Shares of Tesla’s Chinese rivals fell in tandem, with BYD Co (HK:1211) dropping 0.9%, while NIO Inc (HK:9866), Li Auto Inc (HK:2015), Zhejiang Leapmotor Technology Co Ltd (HK:9863), and Xpeng Inc (HK:9868) declined between 0.9% and 2.5%. The downturn followed Tesla’s nearly 4% post-market drop, after its Q3 profit missed forecasts despite achieving record-high revenue.

Tesla’s revenue surge, driven by record vehicle deliveries, was offset by rising costs tied to trade tariffs and artificial intelligence development. The company also cautioned that its capital expenditures would rise sharply in 2026 as it accelerates its shift from electric vehicles toward AI and robotics.

While Tesla’s Q3 delivery boom benefited from the expiration of U.S. EV tax credits, this demand spike may not be sustainable. Outside the U.S., Tesla continues to face slower sales in Europe and Asia, where competition from Chinese automakers is intensifying.

Industry analysts warn that increasing competition and weaker global demand could trigger more price cuts from Tesla, putting additional pressure on Chinese EV makers. Earlier in October, Tesla launched cheaper versions of its Model 3 and Model Y vehicles, intensifying the ongoing price war in China’s EV market.

The Chinese EV sector remains locked in fierce competition as established players and newcomers like Xiaomi Corp (HK:1810) race to capture market share. Tesla’s aggressive price reductions in China have further strained profit margins across the industry, fueling volatility for investors in both U.S. and Hong Kong-listed EV stocks.
