BYD is trading at $9.54, down 4.02%; no reliable report directly links September 29’s decline to a specific announcement.

  • Company news that day included the Dynasty series’ 10 millionth vehicle milestone, but reports do not connect it to the share move.
  • BYD’s Hong Kong shares were reported down 2.51% at HKD 75.75; this is separate-market context, not a substitute for the supplied price data.
  • Broader U.S. indices were mixed with modest moves, and available evidence does not establish a broad-market cause.
