How to read this chart
60‑month range $34.26 – $122.76 · fair‑value band $22.32 – $30.59 · the $89.95 price screens above the $25.31 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Sep 2, 2026.
Analysis
Diodes Incorporated (DIOD) currently trades at $89.95, while our model-based Fair Value estimate is $25.31, implying the stock looks roughly 255.4% overvalued today. The Quality Score stands at 64/100 (solid quality), in the Technology sector. Bull case: the DCF Models group reads highest at a median of $59.67 per share, and 0 of the 26 models we run sit above the $89.95 price. Bear case: the Economic Profit group reads lowest at $12.20, and 26 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Diodes Incorporated generated revenue of $1.6B at a net margin of 5.5%. Revenue grew 22.1% year over year. It earns a return on equity of 4.6%. The balance sheet holds a net cash position of $272M. Fundamentals as of Sep 2, 2026
Our scenario range runs from $22.32 (bear case) to $30.59 (bull case); at $89.95, 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 26% below its 52-week high and 113% 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 −72%, DIOD 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 $1.26 per share, which is 5.0 % 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: DCF Models ($59.67) versus Dividend Discount ($0.0300). Highest evidence: FCF DCF (76).

Quality Score breakdown
Of which business quality 64 · Market factors (momentum, volatility) 52
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.
