MONOLITHIC POWER SYSTEMS INC scores 70 on Long-Term Potential (C+), described by the research model as ordinary compounder. This describes business characteristics only — it is not a forecast of future returns.
Disclosed ownership evidence reads 24 (F): Cautious disclosed activity. 3 tracked managers disclosed a position in the latest reporting period. Ownership filings are historical disclosures, not signals.
MONOLITHIC POWER SYSTEMS INC reads 30 out of 100 on Valuation Intelligence, recorded as Expensive. The stock currently trades above most of its own recent valuation history and above comparable companies. This describes the price being paid relative to the company's financials — it is not a forecast and not a fair value. Valuation Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.
MONOLITHIC POWER SYSTEMS INC reads 43 out of 100 on Capital Returns Intelligence (Moderate Capital Returns), reflecting a dividend that has grown about 22.8% a year and a share count rising about 0.6% a year. Capital Returns Intelligence is a research model and contributes nothing to the Suggested Investment Score or the daily ranking.
No meaningful recorded changes in the stored history.
Risk Intelligence is a core model, Long-Term Potential, Fundamental Momentum, Valuation Intelligence and Capital Returns Intelligence are research models, and Ownership Intelligence is supplemental descriptive evidence. Valuation Intelligence and Capital Returns Intelligence each contribute 0% to the Suggested Investment Score. Nothing here is a recommendation.

Ownership Intelligence summarizes publicly disclosed activity among professional investment managers, broader institutions, company insiders, and significant strategic owners. It adds context to investment research but is not a validated predictor of future performance. Ownership information is publicly reported with a delay; the latest applicable reporting period is 2026-06-30, publicly disclosed 9/11/2026. Congressional activity is unavailable pending legal review and contributes nothing to this reading.
Strong risk profile
Risk Intelligence ranks in the top 12% of qualified companies, with higher_risk price risk.
Exceptional long-term potential
Stored profitability, capital efficiency and reinvestment readings rank near the top of the qualified universe.
Fundamental Momentum is softer
Reported business trends rank below the qualified median.
Ownership evidence is not uniformly supportive
Disclosed elite investor activity evidence is weak or neutral. Ownership evidence is supplemental and never automatically positive.
Ownership evidence disagrees
Different owner groups point in different directions, so the combined reading is best read as mixed rather than uniformly favourable.
Price Risk is less favourable
Price Risk sits in the higher category relative to other qualified companies.

How financially sturdy the company has been when conditions turned against it.
Risk Intelligence reads stored balance-sheet strength, historical downside behaviour and the company's price-risk grouping. A stronger reading describes past resilience; it does not protect against future losses.

Is the underlying business getting stronger or weaker?
Stands at the 50 percentile of eligible companies · stored reading 51 · 16% of this company’s total score
Whether the reported business results have been getting stronger or weaker.
Fundamental Momentum compares recent reported fundamentals with the company's own earlier periods, so improvement or deterioration is measured against its history rather than against a forecast.

Valuation is inherently uncertain. A stock that appears inexpensive can continue falling, and a stock that appears expensive can continue rising. Valuation Intelligence provides context about the price investors are paying — it does not predict short-term market movements, and it never produces a fair value, a price target or a buy or sell range.

Cash returned versus company value
MONOLITHIC POWER SYSTEMS INC reads 43 out of 100 on Capital Returns Intelligence (Moderate Capital Returns), reflecting a dividend that has grown about 22.8% a year and a share count rising about 0.6% a year.
This company spent cash repurchasing stock, but the share count did not fall meaningfully because it also issued shares. Repurchase spending alone did not increase existing shareholders' ownership.
How returned cash was used
Dividends $329.22M · net repurchases $206.94M · total returned $536.16M · 92% of free cash flow
Price data through September 11, 2026 · Financial data through the quarter ended June 30, 2026
Stored readings only. History builds forward from activation rather than being reconstructed.
Only one stored reading exists for this measure so far, so there is nothing to chart yet.
A very high dividend yield may reflect a falling share price or an unsustainable payout. Capital Returns Intelligence emphasizes consistency and sustainability rather than simply rewarding the highest yield.
Announced or gross buyback spending does not always mean shareholders are gaining ownership. Companies can simultaneously issue shares through employee compensation or acquisitions. Suggested Investments therefore considers actual share-count changes alongside repurchase spending.
Capital Returns Intelligence describes how a company returns capital to shareholders. It is not a measure of stock-price performance, it does not predict future returns, and a strong reading is never a recommendation to buy. Dividends and repurchases can be reduced or stopped at any time. Model CAPITAL_RETURNS_INTELLIGENCE_V1, contributing 0% to the Pro Investor Score.

In the company’s own words
Monolithic Power Systems, Inc. is a fabless global company that provides high-performance, semiconductor-based power electronics solutions. Incorporated in 1997, our three core strengths include deep system-level knowledge, strong semiconductor design expertise, and innovative proprietary technologies in the areas of semiconductor processes, system integration, and packaging. These combined advantages enable us to deliver reliable, compact, and monolithic solutions found in storage and computing, enterprise data, automotive, industrial, communications and consumer applications. Our mission is to reduce energy and material consumption to improve all aspects of quality of life and create a sustainable future. We believe that we differentiate ourselves by offering solutions that are more highly integrated, smaller in size, more energy-efficient, more accurate and more reliable with respect to performance specifications and, consequently, more cost-effective than many competing solutions. We plan to continue to introduce new products within our existing product families, as well as new, innovative products that expand our market.
We have over 4,500 employees worldwide, with various locations in Asia, Europe and the U.S.
Semiconductors comprise the basic building blocks of electronic systems and equipment. Within the semiconductor industry, components can be classified either as discrete devices, such as individual transistors, or integrated circuits ("ICs"), in which a number of transistors and other elements are combined to form a more complicated electronic circuit. ICs can be further divided into three primary categories: digital, analog, and mixed-signal. Digital ICs, such as memory devices and microprocessors, can store or perform arithmetic functions on data that is represented by a series of ones and zeroes. Analog ICs, in contrast, handle real world signals such as temperature, pressure, light, sound, or speed. In addition, analog ICs also perform power management functions, such as regulating or converting voltages, for electronic devices. Mixed-signal ICs combine digital and analog functions onto a single chip and play an important role in bridging real world applications to digital systems.
We focus on the market for high performance analog and mixed-signal solutions. High performance products generally are differentiated by functionality and performance factors, which include integration of higher levels of functionality into a single chip or module, greater precision, better power efficiency and density, higher speed, and lower heat and noise. There are several key factors that distinguish the analog and mixed-signal IC markets from digital IC markets. These factors include longer product life cycles, numerous market segments, technology that is difficult to replicate, relative complexity of design and process technologies, importance of experienced design engineers, lower capital requirements and diversity of end markets. We have targeted product and market areas that we believe allow us to operate at above-average growth over the long term compared to the semiconductor industry as a whole.
