"Jim Koch's Expert Advice on Beer-Focused Stock Investing"

Jim Koch, billionaire founder of Boston Beer Co., prefers to invest in the stock market without actively managing it. He believes he cannot outsmart professional investors and instead focuses on random diversification and "zero engagement." Koch outsources the trading of his stocks to his wife's longtime assistant, who was once their babysitter. This strategy has outperformed most actively managed portfolios while requiring less work. Koch's goal is to use securities to maintain his fortune, while his time is better spent running his $2.1 billion business.
