Ambarella is trading at $65.14, down 4.12%, as semiconductor shares broadly weakened amid rising Treasury yields and oil prices.

  • No clear company-specific announcement explaining Ambarella’s October 7 decline surfaced in the search.
  • A report cited declines among several chipmakers amid those market pressures. Broader indices in the supplied market context were down less than 0.5%, offering limited evidence of a market-wide move sufficient to explain Ambarella’s decline on their own.
