Chinese automaker BYD reported a 30% surge in net profit for the second quarter, reaching $1.22 billion (8.2 billion yuan), reversing a trend of four consecutive quarters of declines. The company's overseas deliveries spiked 82% year-over-year to over 471,000 vehicles, with international sales bringing higher margins. Meanwhile, domestic sales dropped 28% to 637,000 vehicles amid an intense price war in China's auto market. The article suggests BYD remains a smart buy due to its vertical integration, technology, and scale, despite domestic market struggles.
