At a share price of $30.24, CoStar Group has seen a 1-day share price return of 2.23% and a 7-day share price return of 5.15%, yet its year to date share price return is down 53.97% and the 1-year total shareholder return is down 68.00%. Recent momentum is therefore building from a much weaker long-term base as investors weigh the stronger earnings, updated guidance, the new buyback progress and the latest multifamily and office market data.
