How to read this chart
60‑month range $300.48 – $1,687 · fair‑value band $221.30 – $379.63 · the $1,214 price screens above the $308.08 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 29, 2026.
Analysis
Monolithic Power Systems Inc (MPWR) currently trades at $1,214, while our model-based Fair Value estimate is $308.08, implying the stock looks roughly 294.0% overvalued today. The Quality Score stands at 74/100 (solid quality), in the Technology sector. Bull case: the Growth Earnings group reads highest at a median of $441.49 per share, and 0 of the 26 models we run sit above the $1,214 price. Bear case: the Asset-Based group reads lowest at $48.16, and 26 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Monolithic Power Systems Inc generated revenue of $3.0B at a net margin of 23.0%. Revenue grew 26.1% year over year. It earns a return on equity of 19.6%. The balance sheet holds a net cash position of $1.1B. Fundamentals as of Aug 29, 2026
Our scenario range runs from $221.30 (bear case) to $379.63 (bull case); at $1,214, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 29% below its 52-week high and 83% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at −59% fair-value upside, at −75%, MPWR screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly $4.99 per share, which is 1.6 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small. Every input is real reported data, nothing guessed.
All 26 models by family
Widest divergence: Growth Earnings ($441.49) versus Asset-Based ($48.16). Highest evidence: FCF DCF (76).

Quality Score breakdown
Of which business quality 74 · Market factors (momentum, volatility) 46
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
