Market Environment - The Hong Kong stock market weakened on that day, with the Hang Seng Index dropping by 1.10% and the Hang Seng Tech Index falling by 2.91%. The automotive sector showed overall weakness, declining by 2.24%, which negatively impacted BYD as a key component stock in the sector [2].

Although the MACD histogram was positive, the momentum was limited, reflecting short-term adjustment pressure [4].
