Nvidia’s 591,078% rally to most valuable stock came in waves

In 1999, Nvidia made its debut on the Nasdaq stock exchange, eventually replacing Enron in the S&P 500. Since then, Nvidia has become the best performing stock of the last quarter-century with a total return of 591,078%. It took less than three years for Nvidia Corp. to ascend into the S&P 500 — replacing the disgraced oil-trading conglomerate Enron, no less.
