New York, January 19, 2026, 19:42 EST — Market closed
Shares of Monolithic Power Systems, Inc. (MPWR) climbed 2.3% to close at $1,033.17 on Friday, marking their fifth straight day of gains ahead of the long weekend. U.S. markets, including the Nasdaq and NYSE, will be closed on Monday for Martin Luther King Jr. Day, with trading picking back up on Tuesday.
Futures plunged immediately. S&P 500 and Nasdaq contracts dropped over 1.2% Monday following U.S. President Donald Trump’s threat of new tariffs targeting several European nations, driving investors to safer bets. “There is obviously a response (in financial markets) to the new tariff threats,” noted George Lagarias, chief economist at Forvis Mazars.

MPWR’s immediate challenge is whether last week’s momentum can carry over into cash trading. Wells Fargo’s Joe Quatrochi bumped the stock from Equal Weight to Overweight and lifted his price target to $1,125 from $1,100. He highlighted a “path for positive estimate revisions,” driven by rising enterprise data demand. Quatrochi also noted a shift in sentiment around analog chips — the power-and-signal components that often fluctuate with inventory cycles. TipRanks
Monolithic Power creates power management chips—the small circuits that convert and control electricity within electronics. Though tiny compared to the devices they safeguard, these chips play a crucial role in balancing performance, heat, and reliability issues that customers are willing to pay to prevent.
The Wells Fargo move wasn’t an isolated one. The bank also upgraded Analog Devices, adding MPWR to a broader “analog recovery” theme. This play hinges on easier year-on-year comparisons and the belief that customers could be restocking inventories after a pullback. Investing.com Nigeria
MPWR shares climbed roughly 6.8% across the five trading sessions ending Friday, pushing gains to around 14% year-to-date, according to MarketScreener data.
That dynamic can flip quickly. If clients pull back on inventory or corporate budgets tighten, a stock that’s climbed sharply could take the first hit. Insiders haven’t been all buyers either; executive vice president Maurice Sciammas reported selling 3,976 shares on Nov. 24 at $895.23.
Monolithic Power’s next major event is on Feb. 5, when it will release its Q4 and full-year 2025 earnings after the market closes, followed by a Q&A webinar at 5 p.m. ET. Tuesday’s open will offer the first glimpse of whether broader market sentiment shifts focus away from these results.
