Movement Alert｜Monolithic Power Systems Rises 5.29% in Regular Trading, Semiconductor Sector Rallies as NVIDIA 800V Power Architecture Partnership and IC Price Hike Expectations Boost Sentiment

Market Focus

Yesterday

On June 18, Monolithic Power Systems rose 5.29% in regular trading, trading at $1547.16/share, with turnover of $246 million. The stock rebounded strongly after a prior session decline, driven by broad semiconductor sector strength and continued positive catalysts.

On the news front, NVIDIA previously announced its next-generation 800V power architecture partner list, with MPS included in the officially endorsed lineup. The comprehensive upgrade of the AI data center power conversion chain directly benefits MPS as a core supplier. Additionally, the power management IC price increase wave continues to build momentum, with the company planning to further expand its pricing adjustment scope in July, reinforcing expectations for improved profitability in the second half.

Within the Semiconductor sector, the broader group posted significant gains. Among individual stocks, Intel rose 8.0%, Micron Technology rose 6.2%, Marvell Technology rose 7.67%, Advanced Micro Devices rose 3.48%, and NVIDIA rose 1.75%, with sector-wide linkage effects providing notable support to MPS shares.
