On September 14, Monolithic Power fell 3.31% in pre-market trading, trading at $1,211.57/share, with turnover of $69,700. The decline was driven by a broad selloff across the semiconductor sector combined with lingering uncertainty from a pending trade investigation.

The semiconductor sector came under heavy selling pressure, with Intel down 5.48%, Micron Technology down 5.03%, Advanced Micro Devices down 4.83%, Broadcom down 2.99%, and NVIDIA down 2.14%, dragging Monolithic Power lower in sympathy. On the news front, Vicor Corporation previously filed a Section 337 investigation request with the U.S. International Trade Commission concerning certain vertical power delivery systems, naming Monolithic Power and its Chengdu and Shanghai subsidiaries as respondents. Should the investigation proceed, it could pose potential uncertainty for the company's U.S. market access for related products, continuing to weigh on market sentiment.

Notably, 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 surpassing the $903.3 million estimate. Q3 revenue guidance of $1.14 billion to $1.16 billion also exceeded expectations.
