We investigate the effects of Regulation FD's reducing information disparity across analysts on their forecast accuracy. Proxies for private information, including brokerage size and analyst company-specific experience, lose their explanatory power for analysts' relative accuracy after Regulation FD. Analyst forecast accuracy declines overall, but analysts that are relatively less accurate (more accurate) before Regulation FD improve (deteriorate) after implementation. Our findings are consistent with selective guidance partially explaining variation in the forecasting accuracy of analysts before Regulation FD.10aFinance1 aFindlay, S.1 aMathew, Prem  uhttps://dev.business.oregonstate.edu/biblio/examination-differential-impact-regulation-fd-analysts-forecast-accuracy-0
