CoStar Stock Plummets 65% From Peak.

CoStar Stock Plummets 65% From Peak. CoStar has crashed from an all-time high of $101.05 in October 2021 to just above $36 today, a stark reminder that even quality companies can become overvalued. Despite this dramatic decline, the company maintains its impressive track record with 59 consecutive quarters of double-digit revenue growth. The core commercial real estate business remains solid with a net cash balance sheet, which should provide downside support. However, investor skepticism centers on the billions invested in Homes.com, though early signs show promise with annual recurring revenue up 58% year-over-year to nearly $100 million. This case illustrates a critical investing lesson: paying premium prices for quality companies can lead to significant losses when market sentiment shifts.
