🔷 William Bernstein originally trained as a neurologist and practiced for 25 years before becoming a financial theorist and investment advisor, bringing a unique scientific perspective to investment writing. 🔷 The book emphasizes that successful portfolio management is more about controlling emotions and behavior than about complex mathematical models or market timing. 🔷 "Rational Expectations" is part of a series called "Investing for Adults," which Bernstein wrote specifically for experienced investors, purposely avoiding the "investing for dummies" approach common in finance literature. 🔷 The author argues that most investors would be better off if they stopped trying to beat the market and instead focused on saving more, spending less, and maintaining a disciplined, long-term investment approach. 🔷 The title "Rational Expectations" is borrowed from economic theory, where it refers to the idea that people make financial decisions based on their expectations about the future, which are shaped by past experiences and available information.
