If you’re a real fool, and you invest in the S&P 500 and hold it for thirty years, you’ll make money.

Warren Buffett once bet that professional fund managers wouldn’t be able to outperform the S&P 500 index over a 10-year long cycle.
In the end, the S&P 500 delivered a cumulative return of 125.8%, with an 8.5% annualized return, while other fund managers averaged only 3% in annualized returns.
Warren Buffett is a real fool.
In the stock market, there are lots of fake fools—many are just pretending. Every day these people chase rallies and sell at the lows; sometimes they’re ecstatic, sometimes they’re heartbroken beyond words; sometimes they brag everywhere with screenshots of their returns, and sometimes they storm into stock forums to curse companies, the CSRC, and curse heaven and earth.
Investing in the Nasdaq 100—over a 30-year timeframe—will also make money. Over the past ten years, its annualized return has been 19%, almost catching up to the performance of “stock god” Warren Buffett.
The Nasdaq 100 has relatively high volatility, so buying it requires being even more foolish—foolish enough to forget that the account is best left alone.
