On June 23, Tower Semiconductor fell 5.3% overnight, trading at $300.05/share, with turnover of $2.30 million.

On the news front, the semiconductor sector experienced broad-based selling pressure, with major peers declining sharply: Micron Technology fell 7.13%, Marvell Technology fell 6.83%, Intel fell 6.27%, Advanced Micro Devices fell 3.67%, and NVIDIA fell 1.87%. The sector-wide risk-off sentiment weighed heavily on Tower Semiconductor despite no company-specific negative catalysts.

Notably, Tower Semiconductor recently announced that it had shipped over 5 million coherent photonic ICs in collaboration with Marvell Technology, demonstrating its advanced silicon photonics platform's scalability in high-bandwidth data center connectivity. The company also signed a multi-year indium phosphide epitaxial wafer supply agreement with IQE to strengthen its silicon photonics foundry supply chain. The pullback appears primarily driven by systematic sector rotation rather than fundamental deterioration.
