Saint selling approximately $2.33 million worth of shares on August 28, 2025, and Cynthia Cammett Cann selling $188,764.05, totaling $4.78 million in insider sales over the last three months.

• InvestingPro’s SWOT analysis on September 17, 2025, indicated strong fundamentals with more cash than debt, but noted the stock appears overvalued relative to its fair value estimate.

The Investment Story: September was a month of strong financial performance and strategic expansion for CoStar, highlighted by the Domain Holdings acquisition and robust Q2 earnings. However, insider selling and mixed valuation signals introduce some caution for investors.

What It Means for Investors: CoStar’s growth initiatives and positive analyst sentiment suggest continued potential, but investors should monitor the impact of insider activity and the evolving housing market. The company’s strong balance sheet provides flexibility for future investments, but valuation concerns remain.

Looking Ahead: Investors should closely watch CoStar’s integration of Domain Holdings Australia, the performance of Homes.com, and the impact of generative AI on EBITDA margins. Monitoring the trend of insider activity will also be crucial.

The Bottom Line: CoStar remains a compelling investment with significant growth potential, but its premium valuation requires sustained performance. The company’s strategic acquisitions and technological advancements position it well for the future, but investors should remain mindful of market risks and insider activity.
