On June 9, Monolithic Power Systems rose 3.09% in pre-market trading, trading at $1,600.00/share, with trading volume of $548,300.

On the news front, the semiconductor sector continued its broad recovery, with sector peers including Micron Technology up 4.97%, Marvell Technology up 3.81%, Intel up 2.31%, Broadcom up 1.13%, and NVIDIA up 0.52%, driving sector-wide linkage that lifted the stock higher.

The rally extends momentum from NVIDIA's recent disclosure of its next-generation 800V power architecture partner list, in which MPS was named as an officially endorsed supplier. The 800V architecture signals a comprehensive upgrade of the power conversion chain for AI data centers, positioning the company as a core beneficiary. Additionally, the power management IC price hike cycle continues to gain traction, with MPS planning to further expand its pricing adjustment scope in July following its initial price increase notice issued in March, reinforcing expectations for improved profitability in the second half.
