New York, Feb 1, 2026, 18:53 (ET) — Market closed.
- Monolithic Power Systems shares ended Friday down 4.9% at $1,124.15 after a wide intraday swing.
- The chipmaker is due to report quarterly and full-year results on Thursday, Feb. 5, after U.S. markets shut.
- Next week also brings a heavy slate of big-company earnings and the monthly U.S. jobs report on Friday, Feb. 6.
Shares of Monolithic Power Systems, Inc. closed down 4.9% on Friday at $1,124.15, after trading as high as $1,188.88 and as low as $1,114.06.
U.S. markets reopen on Monday, Feb. 2, with Monolithic’s results due Thursday and the U.S. jobs report set for Friday. “Expectations have become very, very lofty,” said Jim Baird, chief investment officer at Plante Moran Financial Advisors, warning that stocks can get punished even on growth if it falls short of what investors have priced in.

Friday’s slide came with a broader risk-off turn in U.S. stocks. “Markets are calibrating” to President Donald Trump’s nomination of Kevin Warsh to lead the Federal Reserve and the outlook for monetary policy, said Michael Hans, chief investment officer at Citizens Wealth. Reuters
The company has said it will release fourth-quarter and full-year 2025 results after the market close on Feb. 5 and host a question-and-answer webinar at 5 p.m. ET.
MPWR has been trading near the top of its 52-week range, which runs from $438.86 to $1,188.66, after gains of about 76% over the past year.
Other analog chip names were also lower on Friday. NXP Semiconductors fell 3.15%, while Texas Instruments slid 0.92% and Analog Devices dropped 2.45%, according to MarketWatch data.
For Monolithic, the next move likely comes down to guidance as much as the headline numbers. Investors will be listening for any change in demand signals from cloud and data center customers, and whether automotive and industrial orders keep pace.
Margins matter too. Power chips are a volume game, and small shifts in mix, pricing or costs can show up fast in quarterly results.
But the setup is not forgiving. The stock has been running near its highs and just showed it can swing hard in a single session; any cautious tone on the call, or a guide that points to slower growth, could weigh on it.
The next clear catalyst is Thursday’s results, followed by management’s Q&A at 5 p.m. ET.
