In the eve of the 929 U.S. stock market crash, Joseph Kennedy the elder (the father of President Kennedy) had a shoe-shine boy shine his shoes on the streets of Wall Street.

While getting his shoes polished, the child didn’t just recommend stocks to him—he also enthusiastically taught him investment strategies.

Kennedy immediately realized that when even a shoe-shine boy in the market talks about how to get rich speculating in stocks, it means the last potential buyer has already entered.

After returning to his office, he completely liquidated all the stocks he held and switched to short selling.

A few months later, the U.S. stock market saw the most devastating crash in history. Kennedy not only dodged the crisis, but also used it to accumulate an extremely large family fortune.

When extreme optimism spreads fully to non-professional members of the public, it often means that market liquidity and sentiment have already been drained to their limit.

Buy when no one is asking; sell when the crowd is roaring
