Hong Kong-listed shares of Chinese electric vehicle manufacturers rallied sharply on Thursday, driven by better-than-expected June delivery data.

BYD Company (1211.HK) led the advance, climbing approximately 9%, while Xiaomi Group (1810.HK) rose about 5% as investors digested the latest production and sales figures from the sector's key players.

The positive reception of the delivery numbers helped buoy broader investor sentiment in Asian markets, which were already buoyed by strong earnings reports from US semiconductor giants Micron Technology and Qualcomm earlier in the session.

The EV sector's performance added to the day's broad-based risk-on tone, signaling renewed confidence in Chinese consumer demand and the competitive positioning of domestic automakers.

BYD's significant gain reflects market approval of its continued volume growth, while Xiaomi's rise underscores the growing investor interest in its automotive division as a key growth driver.

The simultaneous strength in both legacy EV leader BYD and tech-turned-auto entrant Xiaomi suggests a broadening of optimism within the Chinese EV ecosystem, rather than a narrow trade in a single name.
