Peter Bernstein argues that the notion of bringing risk under control is one of the central ideas that distinguishes modern times from the more distant past. When investors buy stocks, surgeons perform operations, entrepreneurs launch new businesses, and politicians run for office, risk is their inescapable partner. Bernstein clarifies the major components of risk, explaining how they can be applied to our professional endeavors.
