American investor and philanthropist Warren Buffett, the “Oracle of Omaha,” has finally announced his retirement.

As the curtain closes on one of the greatest investing careers of all time, it’s a good moment to reflect on some of the timeless (and sometimes controversial) wisdom he’s shared over the decades.

One of Buffett’s most famous contrarian takes was hat diversification of investment portfolios isn't all it’s cracked up to be.

“Diversification is protection against ignorance,” he once said. “It makes little sense if you know what you are doing.”

For Buffett, the best strategy has always been to go all-in on a few well-understood, high-conviction investments—think Coca-Cola, American Express, and more recently, Apple. He believed that too much diversification waters down returns and reflects a lack of deep knowledge.

But ,here’s the thing, you are not Warren Buffett. And that’s not an insult, it’s reality.
