Fair value as of: Jul 18, 2026
From 22 valuation models · updated 20 days ago
Fair value updated Jul 18, 2026, revised from $4.74 to $4.75 (+0.2%) since Jun 26, 2026. Share price −1.0% over the past month.
Below-average quality, and screening another 84% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($8.45). The favourable scenario is already priced in.
- Weak quality (42/100) and above fair value at the same time, the margin of safety is missing on both counts.
- A fairly wide model range ($3.38 to $8.45) leaves room in how you read the outcome.
- As a real-estate business, asset- and dividend-based methods carry more weight here than a standard DCF.

How to read this chart
60‑month range $27.14 – $99.74 · fair‑value band $3.38 – $8.45 · the $29.58 price screens above the $4.75 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Jul 18, 2026.
Analysis
CoStar Group (CSGP) currently trades at $29.58, while our model-based Fair Value estimate is $4.75, implying the stock looks roughly 83.9% overvalued today. We read business quality at 42/100 (below-average quality), in the Real Estate 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, CoStar Group generated revenue of $3.4B at a net margin of 0.7%. Revenue grew 22.5% year over year. It earns a return on equity of 0.3%. The balance sheet holds a net cash position of $589M. Fundamentals as of Jul 18, 2026
Our scenario range runs from $3.38 (bear case) to $8.45 (bull case); at $29.58, 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 70% below its 52-week high, currently below its 200-day average. For context, the median of 10 Real Estate peers we cover trades at -2% fair-value upside, at -84%, CSGP 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 22 models by family
Widest divergence: Asset-Based ($151.01) versus Earnings-Based ($3.42). Highest evidence: Growth DCF (80).
