CSGP

CoStar Group's stock (CSGP) has experienced a significant decline over the past year, decreasing by approximately 62.45% to 65.06%, and falling by 20.46% over the last six months. As of October 2, 2026, the share price was $27.38, a substantial drop from $84.80 on October 3, 2025. Key events impacting the stock price in the past six months include strong Q2 2026 earnings reported on July 28, 2026, which saw adjusted EPS of $0.32 and net income surging 817% to $55 million, leading to a 1.67% rise in shares despite a slight revenue miss. However, signs of softening commercial real estate demand in September 2026, as indicated by CoStar's own data, coupled with rising interest rates, led to a stock decline. Overall market sentiment has been wary due to shaky fundamentals, including rising costs outpacing revenue growth, declining operating and free cash flow margins, and a decrease in return on capital. The company also had a 10-for-1 stock split on June 28, 2021.
