Stocks tend to continue rising and outperform the S&P 500 for several years after becoming the most valuable. This pattern has held for companies like Microsoft, ExxonMobil, and Apple. The underlying reason is that companies don't become the world's most valuable without strong business trends supporting them, and these trends often persist for years.
In the past 30 years, four companies have been the most valuable on a U.S. exchange: General Electric (now GE Aerospace), Microsoft, ExxonMobil, and Apple. Each of these companies enjoyed a prolonged period at the top, and their stock prices experienced significant growth even after reaching the top.
