Looking Up to Warren Buffett

T OFTEN SEEMS like every hedge-fund manager is reading from the same playbook about how to look, work and behave. Neatly pressed khakis; thumbs glued to a BlackBerry; slick digs in Greenwich or Manhattan staffed by number-crunching research drones. But apparently, Mohnish Pabrai never got his copy. He wears shorts to his Southern California office, keeps e-mail to a minimum and almost never misses his 4 p.m. nap. And forget goosing returns with fancy computer models or using complex derivatives: Pabrai doesn't even sell stocks short.
