On September 14, Monolithic Power declined 3.15% overnight, trading at $1,193.64 per share, with turnover of $1.9871 million.

The decline was driven by broad-based weakness across the semiconductor sector. Intel fell 5.17%, Advanced Micro Devices dropped 4.67%, Micron Technology declined 4.53%, Broadcom slid 3.02%, and NVIDIA lost 2.17%, creating significant sector-wide headwinds that weighed on the stock.

Adding to the pressure, the overhang from a Section 337 investigation application filed by Vicor Corporation with the U.S. International Trade Commission remains unresolved. The complaint, targeting certain vertical power delivery systems and their components, names Monolithic Power and its Chengdu and Shanghai subsidiaries as respondents. If the investigation proceeds to a formal case, it could introduce uncertainty regarding market access for certain company products in the United States.

On the fundamental side, the company reported strong Q2 results on July 30, with adjusted EPS of $6.50 beating the $5.87 consensus by 10.7%, and revenue of $980.6 million exceeding the $903.3 million estimate. The company also recently signed a long-term manufacturing agreement with GlobalFoundries to expand power management production capacity at a Singapore 300mm facility, targeting high-growth markets beginning in early 2027.
