52-Week Price Performance Analysis

52-Week Price Performance Chart

The stock performance of CoStar Group has illustrated significant volatility over the past year. As of the beginning of January 2026, the stock is priced at $67.24, positioned well below its 52-week high of $97.43 reached in July. Conversely, the stock recorded a low of $62.00, indicating a substantial range of $35.43 within the past year.

Technical Insights

The price chart indicates a bearish trend that transitioned the stock from an initial upward momentum between February and August to declining price levels after peaking earlier in the year. Key technical insights include:

• Support Level: The $67.24 mark represents critical support; failure to hold this level could invite further declines.
• Resistance Level: The absence of significant upward movement suggests a previous resistance near the $100 mark during its peak.
• Moving Averages: The fifty-day moving average stands at $68.76, currently acting as resistance following a trend reversal as the moving average has shifted below recent price action.

Price Momentum

The recent trajectory reflects a cautionary approach as momentum indicates a continuation of the bearish sentiment. The moving average's decline points towards sustained selling pressure. Any spikes that breach the moving average could provide opportunities for a potential reversal and a renewed bullish trend, while ongoing consolidation around the support level could signal a stabilization period.

Financial Performance and Metrics

Financially, CoStar Group projects solid fundamentals and growth visibility, evidenced by key metrics for Q3 2025:

• Total Revenue: Approximately $3.06 billion, up 20% year-over-year to $833.6 million in Q3 2025, surpassing analyst expectations.
• Earnings per Share (EPS): Adjusted EPS registered at $0.23, slightly trailing behind the consensus estimate of $0.30.
• EBITDA: The firm's EBITDA is reported at around $157.8 million, reflecting a robust capacity to generate earnings.

With a target high price set at $105.00 and a mean target price around $91.94, CoStar Group appears undervalued, suggesting roughly 38.4% potential upside from the current price.

Recent News and Developments

Recent developments have brought both opportunities and hurdles:

• Q3 2025 Results: CoStar's disclosure of a 20% revenue increase alongside revised guidance for 2025 revenue (projected between $3.23 billion and $3.24 billion) showcases confidence in continued operational growth.

• Analyst Coverage: Wolfe Research initiated coverage with an "Outperform" rating and a price target of $105.00, citing growth potential from Homes.com and ongoing stability within the CoStar Suite and Apartments.com.

• Increased Competition: A potential risk emerged with reports of Google testing new ad formats that could favor homes-for-sale listings, consequently diminishing traffic to CoStar platforms. Following this news, the stock dropped by approximately 7.8%, underscoring the market's sensitivity to competitive threats.

Market Sentiment and Analyst Recommendations

The overall market sentiment for CoStar Group is cautiously optimistic, given the mixed analytical perspectives:

• A bullish outlook is evident, particularly with Wolfe Research's endorsement coupled with the significant revenue growth disclosed in recent quarters.
• Conversely, concerns surrounding competitive pressure from emerging players in the real estate marketplace introduce elements of uncertainty, which analysts are closely tracking.

Analyst Consensus & Price Targets

With 17 analysts covering CoStar Group, the lack of consensus illustrates divergent investment opinions, as there is no definitive mean recommendation available. Notably:

• Mean Target Price: Approximately $91.94
• Median Target Price: Roughly $96.00

This inquiry into the investment landscape portrays a landscape where investors should weigh both opportunities and risks critically. Caution is advised than following technical and fundamental perspectives until a stronger consensus emerges.

In sum, while CoStar Group, Inc. presents a beacon of growth in the real estate services industry--indicated by buoyant revenue and profit expectations--navigating its stock requires diligence amid external competitive dynamics. Investors should maintain vigilance around key technical indicators, market controls, and evolving industry threats as they evaluate their position or entry into CoStar Group's stock.
