On June 12, Himax Technologies rose 8.69% in regular trading, trading at $17.64/share, with turnover of $46.88 million. The semiconductor sector staged a broad recovery after consecutive sessions of heavy selling pressure, with the TSMC COUPE silicon photonics theme providing ongoing support.

The semiconductor sector saw widespread gains, with Marvell Technology up 11.32%, Micron Technology up 10.74%, Intel up 10.41%, Advanced Micro Devices up 8.2%, and NVIDIA up 2.29%. Himax had previously declined over 30% from recent highs across multiple trading sessions as the broader semiconductor sector faced sustained selling driven by concerns over AI valuation following Broadcom CEO's refusal to raise fiscal 2027 AI revenue guidance. The stock had been identified by the market as a key beneficiary of TSMC's COUPE silicon photonics platform, which enables advanced 3D heterogeneous integration of photonic and electronic integrated circuits for co-packaged optics applications. Research reports indicate the CPO market is expected to exceed $5 billion by 2027 and grow to $15 billion by 2030, with NVIDIA's next-generation CPO switches already adopting the COUPE architecture.
