Just noticed something pretty significant that most people might be sleeping on. Warren Buffett is selling stocks at a pace we've literally never seen before, and honestly, it's worth paying attention to.

So here's what's happening. Berkshire Hathaway dumped roughly 100 million Apple shares in Q3 alone, which means Buffett has cut Apple holdings by 67% over the year. That's massive. But even more telling? They didn't buy back a single share of Berkshire stock last quarter, breaking a six-year streak where he'd been sinking $78 billion into buybacks annually. When Buffett stops buying his own company's stock, that's basically him saying the valuation is stretched.

The real story though is the broader picture. Warren Buffett selling stocks across the board hit $127 billion year-to-date by September—the most aggressive unload in Berkshire's entire history. And they're sitting on a record $325 billion in cash and Treasury bills. That combination tells you something pretty clear: Buffett can't find stocks worth buying right now.

Think about what that means. This is the guy who built his entire fortune by finding undervalued opportunities. If he's hoarding cash instead of deploying it, the market's probably expensive. The S&P 500 is trading at 21.3x forward earnings versus a five-year average of 19.6x. Translation: we're above historical norms.

Now, on Apple specifically. Sure, they've got a solid business—second in global smartphone shipments, first in sales, killer services segment. They beat earnings expectations last quarter, revenue up 6% to $95 billion. But the valuation is brutal. Wall Street expects 10% annual earnings growth over three years, yet the stock's trading at 36.7x earnings. That's a PEG ratio of 3.7 when historical average is 2.7. So yeah, if you're holding Apple heavy, probably makes sense to trim like Buffett is doing.

Here's the thing though—don't interpret Warren Buffett selling stocks as a signal to abandon equities entirely. Berkshire has unique constraints. They're so massive that buying smaller companies barely moves the needle. Buffett said it himself: only a handful of companies could actually impact their bottom line, and they've already picked those over countless times.

But the broader message? Markets are expensive. Buffett's sitting on record cash waiting for better prices. If you're thinking about jumping in right now, maybe wait for a pullback. And if you're already exposed to growth stocks like Apple, this might be the moment to rebalance and take some chips off the table. That's basically what the smartest money in the room is doing.
