HE’S CERTAINLY EARNED HIS RETIREMENT: A 5 million percent return in 60 years leaves Warren Buffett’s legacy unmatched. “From 1964 — the year before Buffett took control of Berkshire — to 2024, the one-of-a-kind conglomerate delivered a compounded annual gain of 19.9%, nearly double the S&P 500′s 10.4%, resulting in an overall return of more than 5.5 million percent, according to the company’s latest annual report. The shares added another 10% to that return in 2025.”
