BYD Co., a Chinese carmaker, has emerged as the world’s leading producer of battery passenger cars, surpassing Tesla in the December quarter with 526,409 deliveries compared to Tesla’s 484,507. BYD’s global sales, including trucks, buses, and plug-in hybrids, reached 918,807, outpacing its American counterpart. Despite its financial success and beating Tesla on key metrics, BYD’s stock is undervalued, presenting an opportunity for investors. The company’s strategic expansion beyond China, with increased overseas sales and assembly plants in Hungary, indicates a global trajectory, potentially propelling BYD to join the ranks of renowned car brands in the near future.
