On June 30, Monolithic Power Systems rose 3.03% in regular trading, trading at $1,344.075/share, with turnover of $61.855 million.

On the news front, the semiconductor sector staged a broad-based rebound, with Advanced Micro Devices up 3.78%, Intel up 1.99%, NVIDIA up 1.64%, Broadcom up 0.76%, and Micron Technology up 0.79%, creating sector-wide momentum that lifted the stock. MPWR had previously plunged 8.69% on June 26 when rumors of OpenAI delaying its IPO to 2027 due to AI valuation fatigue severely dampened market sentiment, triggering concentrated profit-taking across the semiconductor space.

The current rebound reflects technical recovery demand following the prior oversold conditions. Additionally, June 30 marks the record date for the company's quarterly dividend of $2.00 per share, payable July 15, which may have provided incremental support for shareholders maintaining positions through this date.
