On September 11, Monolithic Power rose 3.06% in regular trading, trading at approximately $1,223.04 per share, with turnover of $113 million. The rebound followed a prior session decline triggered by a Section 337 investigation filing, as market panic appeared to ease after one day of digestion.

On the news front, Vicor Corporation filed a Section 337 investigation request with the U.S. International Trade Commission targeting specific vertical power delivery systems, naming Monolithic Power and its Chengdu and Shanghai subsidiaries as respondents. The filing had pressured shares lower in the previous session, with pre-market losses exceeding 3%. However, sentiment stabilized as investors assessed the investigation's preliminary stage and uncertain timeline.

Supporting the recovery, Monolithic Power recently signed a long-term manufacturing agreement with GlobalFoundries to deploy its process technology at GlobalFoundries' 300mm fabrication facility in Singapore, deepening collaboration in power management and reinforcing mid-to-long-term capacity expansion. Additionally, the company maintained its quarterly dividend at $2.00 per share, payable October 15. The broader semiconductor sector also provided a tailwind, with Intel up 2.82%, AMD up 2.02%, Broadcom up 1.46%, and NVIDIA up 0.94%.
