CSGP is in a severe downtrend, with the stock price falling 67.0% over the past year and currently trading at $28.39, just 2.9% above its 52-week low of $28.09 and 70.9% below its 52-week high of $97.43. The price sits at the bottom of its 52-week range, indicating persistent selling pressure and a lack of buying interest, typical of a stock in a bear market. The 1-year price change of -67.0% and the 52-week low proximity suggest the stock is deeply oversold but also reflects fundamental concerns. Short-term momentum remains decisively negative, with a 1-month price change of -17.1% and a 3-month change of -22.2%, both accelerating to the downside. This divergence from the broader market (SPY up 4.1% in 1 month and 11.1% in 3 months) highlights company-specific weakness. The relative strength indicators (1-month relative strength of -21.1% vs. SPY) confirm that CSGP is underperforming significantly, and the consistent decline suggests no near-term reversal catalyst. The 52-week low of $28.09 serves as critical support; a breakdown below this level could trigger further selling toward the next psychological level of $25. The 52-week high of $97.43 is a distant resistance, and any recovery would first need to clear the $35 area (recent consolidation zone). With a beta of 0.735, CSGP is less volatile than the overall market, meaning its decline is not driven by broad market risk but by idiosyncratic factors. The low beta also implies that a market rally may provide only limited lift to the stock.

Revenue has been growing strongly, with Q4 2025 revenue of $900 million, up 26.9% year-over-year from $709.4 million in Q4 2024. The trailing twelve-month revenue is approximately $3.25 billion, driven by the multifamily online marketplace (Apartments.com) at $303 million and CoStar Suite at $277 million in the latest quarter. However, growth is decelerating from the 28%+ pace seen in early 2025, and the residential segment (Homes.com) contributed only $54.9 million, suggesting the heavy investment there has yet to yield proportional revenue. The company is barely profitable, with Q4 2025 net income of $47 million and a net margin of 5.2%, a sharp decline from the 8.4% net margin in Q4 2024. Gross margin remains high at 73.9%, but operating margin fell to 5.5% from 5.6% a year ago, as selling and marketing expenses surged to $377.9 million (42% of revenue) from $308.5 million (43.5% of revenue) in Q4 2024. The company reported negative operating income in Q1 and Q3 2025, indicating that profitability is fragile and heavily dependent on cost control. The balance sheet is solid, with $1.73 billion in cash and a debt-to-equity ratio of just 0.14, providing ample liquidity. However, free cash flow was negative $150.6 million in Q4 2025 due to heavy capital expenditures ($312.7 million), and trailing twelve-month free cash flow was only $117.3 million, yielding a meager 0.4% FCF yield. ROE is negligible at 0.08%, reflecting low returns on equity despite the strong revenue growth.
