Yet despite its dominant position in the real estate data and marketplace industry, shareholders have had little to celebrate lately. The stock has been under intense pressure, tumbling roughly 66.4% from its 52-week high of $90.72 reached last September. The recent selloff has been particularly severe, with shares plunging 6.7% over the past three months, trailing the S&P 500 Index ($SPX), which has rallied 3.6%.
www.barchart.comThe selloff has been even more pronounced in the long term, with CSGP down 54.7% year to date and 65% over the past 12 months, sharply underperforming the S&P 500’s 11.9% and 16.2% gains over both periods, respectively.
Adding to the pressure, CoStar’s technical setup remains firmly bearish, with shares spending most of the past year below both their 50-day and 200-day moving averages.
www.barchart.comCSGP has lagged the broader market as rising expenses, heavier capital investment and declining returns have weighed on profitability and cash generation. Over the past five years, its adjusted operating margin has fallen 16.1 percentage points, while its free cash flow margin has declined 10.8 points. At the same time, shrinking returns on capital suggest the company’s investments have yet to generate the returns investors had hoped for.
Nevertheless, the company is betting big on the U.S. housing market. On Aug. 21, the company completed its $800 million acquisition of Zonda, adding a profitable, subscription-based platform serving more than 3,000 homebuilders, developers, suppliers and lenders. The deal gives CSGP a stronger foothold in the roughly $400 billion U.S. new-home market, while expanding its data, analytics, software and marketplace offerings across the residential real estate ecosystem. Investors appeared encouraged, sending shares 1.8% higher in the following trading session.
CSGP’s weakness becomes even more striking when measured against rival CBRE Group, Inc. (CBRE), which has declined just 15.3% over the past year and 12.6% in 2026, highlighting the steep performance gap between the two real estate players.
Despite CSGP’s steep selloff, Wall Street appears to see a turnaround story rather than a lost cause. Of the 20 analysts covering the stock, the consensus rating remains a “Moderate Buy,” and the average price target of $36.21 points to a potential 18.9% upside from current levels.
