On June 4, Tower Semiconductor declined 6.91% in regular trading, trading at $253.0/share, with trading volume of approximately $77.04 million. The stock has now retreated over 16% from its 52-week high of $302.86.
The decline was driven by a broad semiconductor sector selloff combined with the residual impact of earlier silicon photonics yield rumors. Within the sector, Broadcom fell 15.28%, Micron Technology dropped 8.51%, Advanced Micro Devices declined 6.95%, and Marvell Technology lost 5.92%, reflecting severe sector-wide weakness that weighed heavily on Tower Semiconductor.
Additionally, earlier market rumors regarding process parameter deviations at the company's Fab 9 factory during 1.6T silicon photonics chip fabrication continue to suppress investor confidence. Although core customer Innolight has officially classified the rumor as maliciously fabricated false information, and Tower has responded that process tuning is standard industry practice with no impact on long-term customer relationships or capacity expansion plans, the sentiment damage has not fully dissipated, resonating with the broader sector downturn to amplify the correction.
