Just been looking at the broader market setup heading into the second half of 2026, and honestly there's a solid case for deploying some capital right now if you've got around $1,000 sitting on the sidelines. The S&P 500 is up nearly 100% since late 2022, and both major investment banks are calling for further upside this year. If you're wondering what the best stock opportunities are in this environment, it really comes down to which secular trends you want exposure to.

Let me break down three names that stand out to me, and why they could be worth considering depending on your risk appetite.

First up is the quantum computing angle. Most people don't realize how early we still are in this space. IonQ is one of the pure-play ways to get exposure to this theme. The company designs and manufactures quantum computers and offers services through major cloud providers. What's wild is their revenue more than doubled year-over-year in the first nine months of 2025, with Q3 alone up 222%. That's the kind of growth trajectory that catches attention.

What really matters though is they just hit a 99.99% two-qubit gate performance benchmark, which basically means their systems are nearly error-free. That's a game-changer for mainstream adoption. They're also claiming their cost per system runs about 30x lower than competitors, which is significant. McKinsey reckons the quantum computing market could jump from $4 billion in 2024 to $72 billion by 2035. That's the kind of runway that could make an early player like this absolutely soar if they execute. Sure, the stock isn't cheap right now and it's volatile, but if you're looking for exposure to a disruptive technology, allocating a small portion of your $1,000 here makes sense.

Now, the more immediate opportunity I'm seeing is in AI infrastructure. Gartner is forecasting a 41% jump in AI infrastructure spending this year alone, reaching $1.4 trillion. That's a massive tailwind for companies in the supply chain.

Celestika is a name flying under the radar for a lot of retail investors. They're designing and manufacturing the networking components that go into AI accelerator chips from Broadcom, Marvell, AMD, and Intel. They're also building rack-scale solutions for hyperscalers deploying AI data centers. Their revenue jumped 27% in 2025 to $12.2 billion, and the forecast actually points to acceleration ahead. Here's the kicker though: the stock is trading at just 3.2 times sales. That's dirt cheap for a company with this growth profile and this kind of structural tailwind. This feels like a no-brainer if you're looking for the best stock to capture the AI infrastructure boom.

Micron is another one worth serious consideration. Memory chips are absolutely critical for AI data centers, and there's a shortage that's driving prices higher. The company clocked stunning growth and is trading at less than 10 times sales with a forward earnings multiple of just 11. We're talking about potential earnings that could jump nearly 4x this fiscal year on the back of 100% sales growth. The demand-supply imbalance for high-bandwidth memory in AI data centers should persist through 2028 at least, since adding new chip manufacturing capacity takes years. Micron is up 243% over the past year, but the fundamental story around memory pricing and AI adoption is still in the early innings. This looks like a genuine value opportunity.

So if I had $1,000 to deploy right now, I'd probably split it across these three themes based on my risk tolerance. The quantum play is speculative but potentially massive. The AI infrastructure names are more grounded with visible near-term catalysts. Either way, the macro backdrop is supportive for equities in 2026, and these specific opportunities seem worth exploring if you're trying to figure out what the best stock picks are for your portfolio.
