New York, January 18, 2026, 18:51 EST — The market has closed for the day.
- MPWR climbed 2.34% on Friday, closing at $1,033.17, marking its fifth day in a row of gains
- Chipmakers led gains as U.S. stocks wrapped up a turbulent week before the extended holiday break
- Next up: Tuesday’s reopen and Monolithic’s earnings report on Feb. 5
Monolithic Power Systems Inc shares rose 2.34% to finish at $1,033.17 on Friday, marking their fifth consecutive gain. The stock outpaced several analog and mixed-signal chip rivals during the session. MarketWatch
The move unfolded as U.S. stocks finished almost unchanged in a volatile session before a long weekend. Semiconductor stocks stood out as some of the stronger performers, despite the main indexes posting weekly declines. “One of the other reasons markets have been flat-lining is we’re at the start of the earnings season,” said Anthony Saglimbene, chief market strategist at Ameriprise Financial.

Monolithic, known for its power-management chips that power enterprise data centers, storage, automotive, communications, and industrial equipment, has emerged as a key indicator of investor sentiment on demand for the quieter side of AI and server infrastructure expansion. Reuters
This is crucial now since Monday’s dip and the upcoming earnings reports could flip the tape fast, particularly for high-priced semiconductor stocks where sentiment shifts on a single headline.
Options traders are closely monitoring if post-expiration flows trigger larger daily swings. “I think this options expiration will allow the S&P 500 to start moving around a bit more,” Brent Kochuba, founder of options analytics firm SpotGamma, told Reuters on Friday. Reuters

Next week, chip stocks will hinge on the wider earnings reports and any new insights into corporate spending, especially in data centers and PC-related sectors.

Investors usually focus on the company’s outlook and customer demand across enterprise computing and automotive sectors, along with any remarks on supply constraints and pricing.
The setup works both ways. A holiday-thinned reopen, combined with options positioning and a packed earnings calendar, can fuel volatility. Even if Monolithic stays quiet, a cautious vibe from major tech or chip players could weigh on the group.
As trading picks up Tuesday, eyes will be on MPWR to see if it can maintain gains above last week’s breakout. The semiconductor sector is recalibrating following the long weekend, with Feb. 5 set as the next key date to watch.
