Hey, stock analyst: Your bias is showing - MarketWatch:
"...earnings surprises of firms headed by female, foreign or Democratic CEOs are systematically upward biased, the researchers write in their paper. In other words, because analysts have underestimated the CEOs who don’t belong to their in-group, those CEOs’ companies more often surprise the market when earnings are reported, boosting share prices. “These results are also reflected in analysts’ buy and sell recommendations, with systematically more buy than sell recommendations for stocks of firms headed by CEOs belonging to their in-group,” says the paper, by Sima Jannati and Alok Kumar at the University of Miami School of Business Administration, Alexandra Niessen-Ruenzi at the University of Mannheim in Germany, and Justin Wolfers at the University of Michigan’s Gerald R. Ford School of Public Policy."
