CoStar Group's stock appears undervalued relative to its tailored fair price-to-sales ratio of 4.1 times, even as broader valuation checks yield a mixed score of 3 out of 6. The company currently trades at a P/S of 3.6 times, above the real estate industry average of 2.7 times and the peer average of 1.5 times, but below the 4.1 times fair multiple that adjusts for scale, margins, and risk. The stock has fallen 65.4% over the past three years, and its next move may depend on whether recent price weakness has already priced in pressure on returns or if the current valuation still assumes more improvement than is prudent. Heavy investment in residential and European real estate data, along with integration risk from acquisitions like Zonda, could weigh on how much value investors ascribe to those growth efforts.
