Just caught up on the latest 13F filings and there's some fascinating moves from Warren Buffett's final quarter as Berkshire CEO before his Dec 31 retirement. The Oracle of Omaha basically went out by dumping massive positions in three mega-cap stocks, which honestly tells you a lot about where valuations are right now.

So here's what went down: Buffett sold off 7.7 million Amazon shares (cutting that stake by 77%), offloaded 10.3 million Apple shares (75% reduction since late 2023), and trimmed Bank of America by over 50 million shares. That's not pocket change. The guy was actually a net seller for 13 straight quarters leading up to his retirement, which is pretty telling about his conviction on valuations.

The reasoning is pretty clear if you look at the numbers. Apple's trading at a trailing P/E of 33 now, compared to the low-to-mid teens when Buffett first loaded up back in 2016. Bank of America went from trading at a 62% discount to book value back in 2011 to a 37% premium today. Even Amazon, which has never been cheap by traditional metrics, seems to have gotten pricey enough that Buffett decided to exit.

But here's where it gets interesting. While Buffett was trimming the mega-cap positions, he made one notable new addition: 5 million shares of The New York Times Co., worth about $352 million. That's a brand name play right there. NYT's got 12.78 million digital subscribers now, strong pricing power, and they're actually executing on growth. The forward P/E on that purchase was 24, which is aggressive by Buffett's historical standards, but you can see the logic behind picking up a quality brand with real subscriber momentum.

The whole move feels like a masterclass in valuation discipline. Buffett walked away from positions that got too expensive and picked up something with actual fundamentals backing it up. Whether The New York Times turns out to be the right call long-term remains to be seen, but the broader message is clear: even after decades in the game, Buffett's still disciplined about what he's willing to pay.
