Warren Buffett’s investing genius wasn’t just about what he bought—it was about what he learned.
For decades, the Berkshire Hathaway CEO was known for his disciplined value investing approach. He studied under Benjamin Graham, favored balance sheets over buzz, and warned against straying from fundamentals. But over the course of his storied career, Buffett made one strategic pivot after another—and that rare ability to evolve may be the real secret to his market-crushing performance.
From cigar butts to compounders
Buffett’s early investments were famously scrappy. He sought out “cigar butt” stocks—companies so cheap they had “one puff left” of value. These were small, overlooked businesses trading below their intrinsic worth. But by the 1970s and 80s, a series of high-quality businesses—See’s Candies, The Washington Post, and eventually Coca-Cola—would reshape his view.
The turning point came when Buffett realized that paying a fair price for a wonderful company could yield far greater returns than buying a mediocre company at a deep discount. It was a shift from short-term revaluation to long-term compounding.
He credited his longtime partner, the late Charlie Munger, with helping him make that mental leap. “It took a powerful force to move me on from Graham-style investing,” Buffett once said. “That force was Charlie.”
Buffett 2.0: Embracing tech—and his blind spots
For years, Buffett avoided technology stocks, insisting he wouldn’t invest in businesses he didn’t understand. He famously passed on Amazon and Google in their early days. But he stunned Wall Street in 2016 by buying shares of Apple—a move that would become one of the most profitable bets in Berkshire Hathaway’s history.
Today, Apple is Berkshire’s largest holding, with Buffett calling it “probably the best business I know in the world.”
His willingness to revisit previously closed doors, analyze what he missed, and change his position—even in public—set Buffett apart. “The most important quality for an investor is temperament,” he said. “Not intellect.”
Letting go of ego—and embracing new thinkers
Buffett also understood the power of succession. Rather than try to cling to every decision, he empowered others—first Munger, and now Greg Abel and Ted Weschler—to challenge his views.
He was willing to backtrack when wrong, as with his investment in airlines (which he later exited), or Kraft Heinz (where he admitted to overpaying). For Buffett, success never meant being right all the time. It meant learning, adapting, and making better decisions over time.
