Ambarella is trading 4.5% lower at $69.40, with no clear company-specific announcement or event explaining the decline.

  • On September 28, renewed doubts about a U.S.-Iran truce lifted oil prices and bond yields, while U.S. equity futures fell.
  • This risk-off backdrop is a plausible contributor, but available evidence does not establish a direct cause for Ambarella’s move.
