Ouster is trading 10.1% down now at $43.26 after broad technology and AI-stock weakness, rather than a clear company-specific negative announcement.
- The August 18, 2026 market selloff followed the expiration of the U.S.-Iran ceasefire memorandum, oil rising above $90, and the 30-year Treasury yield reaching its highest level since 2007, pressuring growth-stock valuations.
- Ouster announced a Trossen Robotics and Stereolabs partnership, but it did not explain the decline.
