Monolithic Power Systems shares rose 16.60% to $1388.05 on Tuesday. The primary driver was a broad rally in beaten-down semiconductor names following the sector's steepest one-day rout in 19 months. Dip-buyers moved into hardware stocks, lifting MPWR alongside peers like Broadcom and Applied Materials.
What Happened
The surge followed strong third-quarter results that included a revenue beat and a robust outlook for AI data-center growth. This marked the fifth consecutive gain for the stock in seven sessions. The company recently authorized an additional $500 million share repurchase program. Separately, Reed Semiconductor prevailed in a patent lawsuit brought by Monolithic Power Systems. The move coincided with a wider recovery in chip stocks after a period of significant volatility.
What The Data Shows
The stock printed 68 fresh 52-week highs on November 9, 2026. It currently trades within a 52-week range of $833.18 to $1714.09. Fundamentals show a market cap of $58.1 billion, a P/E of 65.6, and trailing twelve-month revenue growth of 40.5%. The company maintains a net margin of 23.9% and a beta of 1.72. Over the last eight sessions, the stock moved 2.8% from $1345.45 to $1382.96. Insider activity shows five sells totaling $40.5 million in the last 90 days, with no buys. CEO Hsing Michael sold shares on September 28, 2026. Congressional disclosures include a sale by Donald J. Trump in August 2026 and a small buy by Representative Ro Khanna in July 2026.
What To Watch
Investors will monitor coverage breadth as the stock consolidates its gains. The recent authorization of a new buyback program and the ongoing momentum in the semiconductor sector remain key factors for the near term.
