The stock market has not been kind to investors this year. The S&P 500 had its worst first half since 1970, and the Nasdaq Composite is currently 28% off its high. But the market has recovered from worse in the past, and there is no reason to believe this situation is any different. Eventually, the next bull market will erase those losses.

In the meantime, many beaten-down stocks are brimming with potential, and that creates a buying opportunity for patient investors. For instance, Roku and MercadoLibre could both grow sixfold over the next decade, meaning shareholders could see a 500% return by 2032.
