Investing with conviction isn't necessarily a good idea. That may seem a bit counterintuitive, particularly with respect to manager selection. After all, an active manager's best ideas can shine more in a compact, high-conviction portfolio than they could in a better-diversified portfolio. It's hard to surmount active fees without taking bold active bets. But as portfolio concentration increases, so do the odds of underperforming the market.
