Analysis
Diodes Incorporated (DIOD) currently trades at $105.17, while our model-based Fair Value estimate is $25.64, implying the stock looks roughly 75.6% overvalued today. The Quality Score stands at 63/100 (solid quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: 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 Jul 19, 2026
Our scenario range runs from $18.35 (bear case) to $30.59 (bull case); at $105.17, 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 14% below its 52-week high and 149% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at -76%, DIOD screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted 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.
All 26 models by family
Widest divergence: DCF Models ($51.92) versus Dividend Discount ($0.0300). Highest evidence: Growth DCF (80).
