CoStar Group Inc.

CoStar Group Inc.

CoStar Group Inc. (CSGP) is a leading provider of commercial real-estate information, analytics and online marketplaces. The company collects property data, offers subscription-based research and powers listing platforms such as LoopNet and Apartments.com, serving brokers, landlords, investors and occupiers. Its business is driven by recurring revenue from software-as-a-service and marketplace listings, which can create durable margins but also makes performance sensitive to commercial property market cycles. With a market capitalisation of about $32.56B, CoStar has invested heavily in data acquisition and technology to build scale and network effects. Investors should note the potential for steady cash generation alongside historically high valuation multiples, and recognise risks including cyclical demand for commercial space, competitive threats, and the challenge of maintaining data quality. This is general educational information and not personal advice; outcomes can vary and capital is at risk.

Why It's Moving

CoStar Group Inc.

CoStar Group's shares dip amid share price weakness, but analysts spotlight undervaluation and robust growth ahead.

CoStar Group (CSGP) has faced recent share price pressure, sliding over the past few months despite solid revenue and earnings momentum in commercial property data. Investors are reassessing the stock's valuation as it trades at a discount to fair value estimates, fueled by expectations of margin expansion and platform scaling.

Sentiment:
🐃Bullish
  • Quantum Capital Management sold 23.5% of its CSGP stake in Q2, part of ongoing institutional adjustments, while smaller funds initiated positions.
  • Recent analysis pegs CSGP as 26% undervalued at $68 closing price versus $91.94 fair value, banking on 16.9% annual revenue growth and margins surging to 18.6% in three years via Homes.com expansion.
  • November reports show strengthening national home price appreciation and multifamily rent growth, bolstering CoStar's core data services amid a softening stock performance.
