On May 20, BYD Company (01211.HK) fell 3.04% in regular trading, trading at HKD 91.4/share, with trading volume of HKD 474 million, hitting a recent low.

On the news front, BYD reported Q1 net profit of RMB 4.085 billion, down 55.38% year-over-year, as an intensifying domestic price war, surging R&D expenses of RMB 11.34 billion, and a significant swing in financial costs — from a RMB 1.908 billion forex gain last year to a RMB 2.1 billion forex loss this quarter — severely compressed margins. Q1 revenue fell 11.82% to RMB 150.225 billion, while sales volume declined 30.01% to 700,500 units.

Adding to the pressure, BYD's rollout of its second-generation flash charging technology faces mounting regulatory scrutiny, including new fast-charging safety national standards and a six-ministry inspection campaign. Markets are concerned that the tightening regulatory environment may delay monetization of BYD's technological lead. The broader HK-listed auto sector continues to weaken, with industry-wide selling sentiment intensifying downward pressure on the stock.
