Buffett wasn't talking about billionaires per se paying their fair share in taxes. He did say that the top 800 in the U.S. companies should pay their taxes and argued that if they did, no other person would have to pay federal taxes, including income or estate taxes or social security.

Buffett also sold shares of Apple in 2019 and 2020 for tax purposes. In 2021, he admitted that was probably a mistake. Still, with the massive run in Apple shares since then, Buffett thought it would be worth it to take the tax bill on the gains now. He could always add shares back to the position if the opportunity presents itself.

If any investor has stood the test of time, it’s Warren Buffett, and with good reason. For years, the “Oracle of Omaha” has had a rock star-like presence in the investing world, and his annual Berkshire Hathaway shareholders meeting draws thousands of loyal fans who are investors.

Berkshire's 5.1% stake in Apple is worth over $150 billion. However, the tech giant isn't Buffett's top holding in his Berkshire Hathaway portfolio. To be sure, Apple remains by far the top stock that Berkshire owns.

According to Berkshire Hathaway 's most recent 13F filing, Buffet sold 116 million shares of Apple ( AAPL -2.11%) during the first quarter. Just three years ago, Buffett proclaimed that Apple was "probably the best business I know in the world" during an interview on CNBC.
