Investors were bullish on Chinese electric vehicle stocks Monday morning after companies such as BYD, XPeng ( XPEV ), Li Auto ( LI ), and others released October delivery data late Friday.

BYD’s EV sales rose roughly 12% from last year while sales of the company’s hybrid vehicles surged over 62%, sending its shares on the Hong Kong stock exchange up 3.5% in Monday morning trading. Though while Li Auto’s deliveries rose 27% year-over-year to 51,443, its U.S.-listed shares dropped 0.26% Monday morning.

US-based Tesla ( TSLA ), however, saw sales of its EVs manufactured in China drop 5.3% from last year and over 20% from September, according to data from the China Passenger Car Association reported by Reuters Monday. The EV giant’s stock fell as much as 2.4% in morning trading Monday.

XPeng said it set a new monthly record for deliveries at 23,917, a bump of 20% from last year. The uptick seemingly sent its U.S.-traded shares up around 6% Monday morning.

Nio’s ( NIO ) deliveries were also up just over 30% from October 2023 at nearly 21,000 vehicles. The company’s U.S.-traded shares also rose around 1.7%.
