On September 22, Monolithic Power rose 3.22% in regular trading, trading at $1,257.52/share, with turnover of $2.95 billion. The stock extended its recovery momentum as a recently announced strategic manufacturing partnership continued to fuel investor optimism, coinciding with a broader semiconductor sector rally.

On the news front, Monolithic Power and GlobalFoundries recently signed a long-term manufacturing agreement to deploy MPS proprietary process technology at GlobalFoundries' 300mm fabrication facility in Singapore. The partnership aims to significantly scale production capacity for high-performance power management solutions and strengthen supply chain resilience. The collaboration builds on MPS's expanding footprint in AI power delivery, following the launch of highly integrated power modules covering 15A to 240A output for AI accelerator cards and server platforms.

The broader semiconductor sector traded firmly higher, with Intel up 13.42%, Advanced Micro Devices up 9.28%, Micron Technology up 2.48%, NVIDIA up 1.41%, and Broadcom up 0.76%, providing additional tailwinds. The stock had previously pulled back over 4.7% on September 14 amid sector-wide weakness and litigation uncertainty, and has since been in a recovery phase.
