Do you want greater investment returns? You need to assume more risk. So says academic finance, which rests almost entirely on the principle that reward necessarily entails and is commensurate with risk. Indeed this assumption has at least an element of truth to it, inasmuch as stocks are riskier than bonds, and also tend to deliver greater returns than bonds over longer (say, multiyear) periods of time.

Hedge fund manager and author of "The Dhandho Investor," Mohnish Pabrai, begs to differ with the academics. Like so many value investors who've come before him (and to whom he's duly deferential), Pabrai provides a framework for selecting unloved, overlooked, forgotten, and seemingly boring businesses that are selling at cheap enough prices to minimize risk and maximize returns.
