CoStar Group is trading 10.61% down at $28.61 as investors focus on weak Q3 bookings despite record profitability and earnings beats. - Annualized net new bookings were $37 million, down from $84 million a year earlier; management cited economic headwinds and slower sales-force growth. - Revenue and adjusted EPS topped analyst estimates, but coverage linked the post-earnings selloff to growth concerns. - The decline extends the previous session’s 5.01% drop; broad indexes were only modestly higher, making the company-specific earnings reaction the clearer explanation.
