So Warren Buffett finally stepped down after six decades running Berkshire Hathaway. What's interesting isn't just that he's gone, but what his portfolio moves tell us about where smart money is heading in 2026.

Buffett always bought stocks like he owned them forever. That long-term thinking shaped everything Berkshire held. Even though he's handed over the reins, his fingerprints are all over the portfolio, and some of those positions look pretty compelling right now.

Take Alphabet. Last spring, people were worried Google's AI game was falling behind. The stock took heat. But then the company committed between $91 and $93 billion to capex for AI infrastructure, and suddenly the narrative shifted. Gemini got better, Waymo started turning heads, and investors realized Google wasn't sleeping.

Here's what caught my attention: In Q3 2025, Buffett's team loaded up on Alphabet, buying over 17.8 million shares. That's not casual portfolio tinkering. That's conviction. They added nearly $4.3 billion to the position, making it close to 2% of Berkshire's total holdings. Even with Berkshire sitting on $382 billion in cash, that kind of focused bet matters.

The valuation's interesting too. Alphabet's trading at a 31 P/E ratio, which actually matches the S&P 500 average. For a Magnificent Seven stock, that makes it one of the cheaper ones. The company's still generating massive free cash flow—nearly $74 billion last year without even counting capex. That means the AI investment isn't killing profitability; it's coexisting with it. As the company keeps improving its tech and pushing AI innovation, there's real room for the stock to run higher.

Then there's Amazon. Different story, same theme. Amazon's also betting big on AI—$120 billion in capex over the past 12 months. That's serious money. But here's the thing: they still generated $15 billion in free cash flow on top of that spending. The AI investments are supposed to unlock value in cloud services, e-commerce, and digital advertising.

Amazon's had a rough few months though. Stock's been flat while investors rotated out of AI names, and AWS is facing real pressure from Microsoft Azure and Google Cloud. That competition is showing up in the stock price. But Buffett's team has held most of their Amazon shares since 2019 and stopped selling back in 2023. They're clearly not spooked.

What's changed is the valuation. Amazon's now trading at 32 times earnings, barely more expensive than Alphabet. For a company with that kind of free cash generation and AI tailwinds, that's not a bad entry point.

The pattern here is pretty clear: Buffett's warren buffett stock picks show he's betting on AI leaders with real cash generation, not just hype. Both Alphabet and Amazon are printing free cash while investing heavily in the future. That's the kind of setup that typically leads to outperformance.

If you're looking at where experienced investors are actually putting money in 2026, watching what Buffett's doing is still probably the smartest move. These two positions suggest the best returns might come from companies that are investing in AI but already have the business model to fund it without destroying shareholder returns. That's rarer than you'd think, and it's probably why these warren buffett stock picks deserve attention.
