In addition to Buffett, BlackRock also reduced its position in BYD's H shares in October.

On October 28, BYD announced its third-quarter earnings, showing that it reported net profit attributable to shareholders of RMB 5.7 billion ($786 million) in the third quarter, up 350.1 percent year-on-year and up 105.1 percent from the second quarter.
