New York, January 31, 2026, 18:51 EST — The market has closed.
- MPWR shares ended the day at $1,124.15, slipping roughly 4.9%.
- After four consecutive rises, the stock hit a fresh 52-week high just the day before.
- Results are expected after the close on Feb. 5, followed by a Q&A webinar at 5 p.m. ET.
Monolithic Power Systems (MPWR) shares dropped 4.9% on Friday, closing at $1,124.15 ahead of Monday’s U.S. market reopening.
Timing is key. Investors enter the new week eyeing the chipmaker’s upcoming results, with the stock having just hit fresh highs that could amplify any unexpected moves — positive or negative.
Friday’s retreat came on a volatile day for stocks. The major indexes closed lower as investors digested Donald Trump’s nomination of Kevin Warsh to lead the Federal Reserve after Jerome Powell stepped down, alongside fresh inflation data. “Markets are calibrating to Trump’s pick of Kevin Warsh … and the outlook for monetary policy,” noted Michael Hans of Citizens Wealth. Edward Jones strategist Angelo Kourkafas pointed to mixed results from tech earnings and ongoing inflation concerns. Reuters
Earlier in the session, the stock climbed 1.84% to $1,183.15, marking its fourth consecutive daily rise and hitting a fresh 52-week high, according to MarketWatch data. Texas Instruments rose 1.30%, Analog Devices inched up 0.34%, while NXP Semiconductors dropped 2.72%.
Monolithic Power Systems operates as a “fabless” chipmaker, designing semiconductors while outsourcing their production. The company specializes in power-management components that regulate and convert electricity within electronic devices. Its products serve sectors including enterprise data, storage and computing, automotive, communications, consumer, and industrial markets. Reuters
Monolithic Power Systems is gearing up to release its fourth-quarter and full-year 2025 earnings after the market closes on Thursday, Feb. 5. Along with the numbers, the company will provide written commentary. A Q&A webinar is scheduled for 2 p.m. PT / 5 p.m. ET.
Traders are focused on demand cues from data-center and server construction, where power chips make up a minor cost but are essential in every unit. Margins will also be scrutinized, particularly if packaging and assembly expenses shift.
Expectations swing both ways. High-multiple tech stocks, expensive compared to their earnings, can plunge sharply on cautious outlooks, even if the quarter appears solid on paper.
Markets are closed for the weekend, so all eyes turn to Monday’s open for the first sign of direction. After that, the focus shifts swiftly to the Feb. 5 report and the live Q&A session.
