Just caught something pretty interesting in the latest 13F filings. Warren Buffett wrapped up his final quarter as Berkshire Hathaway's CEO before stepping down on Dec 31st, and man, he really cleaned house on some of his biggest holdings.

The numbers are pretty striking - he dumped 7.7 million Amazon shares (77% reduction), nearly 10.3 million Apple shares (75% cut since late 2023), and over 50 million Bank of America shares (50% reduction). That's not just trimming positions, that's a serious exit strategy. When you look at the pattern, Warren Buffett and his team have actually been net sellers for 13 straight quarters leading up to his retirement.

What's the common thread here? Valuation. Apple's trading at a P/E of 33 now - way different from the mid-teens multiple when he first bought in back in 2016. Bank of America went from trading at a 62% discount to book value (when Buffett backed them in 2011) to now trading at a 37% premium. Even Amazon, which has never been cheap, got the axe. The message seems pretty clear: Warren Buffett wasn't comfortable with where prices had climbed.

But here's where it gets interesting. While he was selling off those mega-cap positions, he made one bold new move - scooped up over 5 million shares of The New York Times for about $352 million. That's a pretty aggressive forward P/E of 24, which is notable considering how disciplined he usually is about waiting for better prices.

The logic makes sense though. NYT has the brand trust, solid digital subscription growth (12.78 million as of year-end), strong pricing power, and double-digit digital ad growth. It's got that classic Buffett DNA - recognizable brand, steady buybacks, modest dividend.

So what's the takeaway from Warren Buffett's final quarter? Sometimes the best move is knowing when to exit, even from positions that worked. And sometimes it means being willing to pay up for quality when the fundamentals are actually solid.
