Today marks the end of an era. Warren Buffett, the legendary investor who turned a failing textile mill into one of the world's most valuable companies, is wrapping up his final trading day as CEO of Berkshire Hathaway Inc. (BRK.B) after more than 55 years at the top.
The Numbers That Defy Belief
Let's talk about the scorecard, because it's honestly hard to comprehend. When Buffett took control of the struggling textile maker in 1965, Berkshire's shares were trading around $19. He officially became CEO in 1970. Fast forward to today, and those shares now trade at $755,400.
That's a 3,975,690% gain. Yes, you read that right. Nearly 4 million percent.
The compound annual growth rate over this period clocks in at 19.3%, which happens to be more than double the S&P 500's 7.55% CAGR over the same stretch. To put it in more digestible terms: if you had invested $100 in Berkshire when Buffett took over more than half a century ago, you'd be sitting on $3.96 million today. That same $100 dropped into the S&P 500 would have grown to $7,881.
The difference between $7,881 and $3.96 million is the entire story of Buffett's career. It's a masterclass in what consistent, disciplined investing can do when you let it compound over decades.
The Empire He's Leaving Behind
At 95 years old, Buffett is handing over a financial fortress. Berkshire is now worth $1.08 trillion, with $381.67 billion sitting in cash and $127.24 billion in debt. It's become a sprawling global conglomerate that touches almost everything: insurance, railroads, utilities, manufacturing, consumer brands, and one of the largest publicly traded equity portfolios on the planet.
The company owns household names like Geico, BNSF Railway, Berkshire Hathaway Energy, Precision Castparts, Dairy Queen, and See's Candies. Its public equity portfolio reads like a who's who of American business, with significant stakes in Apple Inc. (AAPL), American Express Co. (AXP), Coca-Cola Co. (KO), Bank of America Corp. (BAC), and UnitedHealth Group Inc. (UNH).
Who's Taking Over?
Greg Abel, Berkshire's vice chairman, will step into Buffett's shoes starting January 1, 2026. The decision was announced during the company's annual shareholder meeting in May 2025, putting an end to years of succession speculation.
Abel isn't exactly new to the Berkshire universe. He first entered the fold in 1999 and has been vice chairman for non-insurance operations since 2018, overseeing the company's diverse portfolio of subsidiaries across railroads, utilities, energy, manufacturing, and retail. If anyone understands how this sprawling empire operates, it's him.
How the Stock is Trading
Berkshire Hathaway's Class B shares closed up 0.53% on Tuesday at $503.71 and were down 0.09% in overnight trading. The stock scores high on value metrics but shows weaker momentum and quality indicators. Still, it maintains favorable price trends across short, medium, and long timeframes.
As Buffett closes out his final day at the helm, the question on everyone's mind is simple: can anyone replicate what he's built? The answer is probably no, but that's not really the point. Abel's job isn't to be Warren Buffett 2.0. It's to keep the machine running and prove that what Buffett built can outlast even its legendary architect.
