So we're halfway through 2026 now and I've been thinking about which stocks actually delivered on their promise this year. Back when everyone was making their top 10 picks for 2026, there was a pretty clear thesis running through most portfolios: AI infrastructure spending was going to keep accelerating, cloud giants would dominate, and a few beaten-down names from 2025 could stage comebacks.

Let me walk through the ones that stood out to me. The chipmakers were always going to be critical here. Nvidia's been the obvious play since the whole AI buildout kicked off in 2023, and honestly, nothing's changed that thesis. We're talking about hyperscalers spending record amounts on data centers and GPU infrastructure. Nvidia's projecting that global data center capex alone could hit 3 to 4 trillion by 2030. That's the kind of tailwind that keeps a stock relevant for years.

But here's what's interesting: AMD and Broadcom have been quietly gaining ground. AMD's targeting 60% compound annual growth in data center revenue over five years, and Broadcom's custom AI accelerator approach is actually winning deals with the big cloud providers. Their AI semiconductor revenue jumped 74% year-over-year in Q4 fiscal 2025, and they were expecting that to accelerate past 100% in the following quarter. Taiwan Semi is the foundry play here, and as long as all these fabless chip companies keep designing new silicon, TSMC keeps printing money.

On the cloud and AI platform side, the dynamics got interesting. Alphabet's Gemini went from being written off to actually competing with the best generative AI models out there. Google Search is still a cash machine, and Google Cloud is becoming a real force. Meta had this weird moment where the market freaked out about their capex plans, but if you actually looked at their Q3 numbers, revenue was up 26% year-over-year. The stock got cheap on that overreaction, and that's typically when you want to be paying attention.

Amazon only gained 3% through most of 2025, which seemed weird given that their revenue was growing at a 13% clip in Q3. The advertising business and AWS are both positioned to keep accelerating in 2026. Sometimes the best opportunities come from stocks that just haven't gotten their moment yet.

Then there are the recovery plays. PayPal got absolutely hammered, down about 30% for the year, but the business was actually delivering solid earnings growth. At 11.5 times forward earnings, it was dirt cheap. The Trade Desk took it even worse, down 70% after their platform migration to Kokai got messy. But Wall Street was still modeling 16% revenue growth for 2026, and at a forward P/E of 20, that looked like a potential inflection point.

MercadoLibre is interesting because it's been the Latin American e-commerce story that just keeps working. Up 20% for the year but down 20% from its July high, it's had a few pullbacks that turned out to be great buying opportunities in the past.

The thing about building a top 10 stock advisor list is that you're really just trying to identify companies with strong structural tailwinds and reasonable valuations. Some of these are obvious mega-cap plays, some are recovery situations, but the common thread is that they all had legitimate reasons to outperform. Whether they actually did is another story, but that's what made the thesis worth paying attention to.
