Investors Lose Returns by Trading Too Much and Selling Under Stress

Barry Ritholtz, the fund manager and author of “How Not to Invest,” argues that most investors lose money less because markets are unknowable than because they create too many opportunities to make bad decisions. In a conversation with Sam Parr and Shaan Puri, he makes the case for a broad, low-cost indexed core, tightly contained speculation, fewer selling decisions, and an information diet built around humility rather than prediction.
