Just noticed something pretty telling about what Buffett sells lately. The guy stepped back after 65+ years running Berkshire, and right before he did, he was basically dumping stocks every single quarter for three straight years. That's not exactly the "forever hold" mentality he's famous for preaching.

So what exactly did Buffett sell? The 13F filings show he trimmed positions in Apple, Bank of America, Verisign, DaVita, D.R. Horton, and Nucor. But here's the thing - the Apple and BAC sales make the most sense when you look at valuations. Apple's been crushing it as a cash machine with buybacks and dividends, but the stock's trading at a P/E ratio that doesn't match its growth rate anymore. Same deal with Bank of America - the share price had basically doubled from where Buffett originally bought in, and it was approaching 2x tangible book value by end of 2025.

The Verisign move was interesting because Buffett sold it down below the 10% disclosure threshold and locked in an agreement not to sell more for a year. DaVita was more about honoring a buyback agreement. But the real story isn't what Buffett sells - it's what he's buying instead.

Here's where it gets wild. While Buffett sells stocks, he's plowing nearly $10 billion into Treasury Bills. Three-month T-bills are yielding around 3.7%, which honestly isn't crazy high, but here's why he's doing it. T-bills are backed by the full faith of the U.S. government, zero interest-rate risk on short-duration paper, and after getting burned on 15-year bonds in the 1970s, Buffett basically said "never again." He's sticking to six months or less.

What's crazy is that T-bills and cash now make up roughly a third of Berkshire's entire portfolio value. That's one of the largest cash allocations in the company's history. And Buffett's pretty explicit about it - he wrote in the earnings release that they're prioritizing "safety over yield" on short-term investments. Translation: he thinks most stocks look overvalued right now.

Now, the thing about Berkshire is that it needs to deploy hundreds of millions minimum, ideally tens of billions, to make a real dent. That's a completely different game than what individual investors face. For most of us, there's actually way more opportunity in smaller and mid-cap stocks where valuations haven't gotten as stretched. But when Buffett sells this aggressively and parks this much cash, it's definitely a signal worth paying attention to about where he sees value - or more importantly, where he doesn't.
