- Credo Technology, Marvell, Coherent, Applied Optoelectronics, and AXT are also falling.
- Nasdaq weakness and semiconductor declines are adding pressure to growth stocks amid broader risk-off trading.
- The move appears tied to sector-wide selling and renewed concern about AI investment costs, rather than a newly reported company-specific announcement. No trading-volume figure was provided.
