AOI Electronics is trading 10.91% down at ¥2,385, amid broad weakness in Asian technology and semiconductor stocks. - No confirmed company-specific announcement explaining the decline was found. AOI Electronics’ IR calendar lists second-quarter FY2026 results for October 30, but that does not establish a cause. - The wider move followed disappointing U.S. technology earnings and renewed concerns about returns on AI spending; Japan’s Nikkei and regional chipmakers also fell.
