The S&P 500 has rocketed 49% since bottoming out in 2022. The good news is that we're less than two years into this bull market, and the average bull market lasts 4.9 years with an average return of 177%, according to Stifel. History says investors are looking at several more years of easy pickings.

Wall Street's main stock indexes opened higher on Friday, with the S&P 500 near record highs, after soft inflation data raised expectations that the Federal Reserve could now focus on shoring up the labor market and continue easing interest rates.
