Fair value as of: Aug 13, 2026
From 26 valuation models · updated yesterday
Fair value updated Aug 13, 2026, revised from $99.20 to $109.70 (+10.6%) since Jul 14, 2026. Share price +2.4% over the past month.
A solid business, but screening 62% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($177.12). The favourable scenario is already priced in.
- The model range is unusually wide ($59.92 to $177.12). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Solid but not exceptional quality (66/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis
Bel Fuse Inc (BELFB) currently trades at $286.01, while our model-based Fair Value estimate is $109.70, implying the stock looks roughly 61.6% overvalued today. The Quality Score stands at 66/100 (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: medium).
Over the trailing twelve months, Bel Fuse Inc generated revenue of $702M at a net margin of 7.8%. Revenue grew 17.2% year over year. It earns a return on equity of 14.3%. Net debt stands at $164M. Fundamentals as of Aug 13, 2026
Our scenario range runs from $59.92 (bear case) to $177.12 (bull case); at $286.01, 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 last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat. The share trades about 8% below its 52-week high and 227% 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 -62%, BELFB screens cheaper 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 ($115.97) versus Dividend Discount ($4.33). Highest evidence: Growth DCF (80).
