Been looking at what to do with some spare cash, and honestly the market setup right now is pretty interesting. The S&P 500 has been crushing it for over three years now, up nearly 94% since late 2022, and the consensus from the big banks is we could see another solid run this year. Deutsche Bank's calling for 8,000 on the index by year-end, Goldman Sachs is talking 12% upside. So if you've got around $1,000 sitting there after bills and emergency fund are sorted, there's a case for putting it to work.

I've been digging into what looks like solid opportunities across a few different themes. First up is the quantum computing angle, which I know sounds futuristic but hear me out. IonQ is the play here if you believe in that narrative. The quantum computing market is expected to balloon from $4 billion now to $72 billion by 2035 according to McKinsey. IonQ's been growing like crazy - their revenue more than doubled year-over-year in the first nine months of 2025, hitting $68 million with Q3 up 222%. They just hit a world record with 99.99% accuracy on their quantum systems, which is actually a big deal for practical adoption. The stock's expensive at 158x sales and volatile as hell, but if you're thinking long-term, throwing a small amount at this could work out.

Now, the AI infrastructure theme is where I'm seeing the real momentum play out right now. Gartner's forecasting AI infrastructure spending jumps 41% this year to $1.4 trillion. That's massive, and it flows through to companies building the actual hardware and components.

Celestika is one of those picks - they're designing and manufacturing the networking components that go into AI accelerator chips from Broadcom, Marvell, AMD, Intel. They're also building out the rack-scale solutions for hyperscalers deploying AI data centers. Revenue jumped about 27% in 2025 to $12.2 billion and the forecast shows acceleration ahead. Trading at just 3.2x sales, it looks like a reasonable entry point if you're looking for stocks to buy now with solid growth visibility.

Micron is another one worth considering. Memory chips are the unsung hero of this whole AI buildout, and there's a genuine shortage driving prices up. Their revenue could roughly double in the current fiscal year, and they're trading below 10x sales with a forward PE of 11. They've already popped 243% over the past year, but the thesis is still intact - memory demand from AI data centers is going to stay hot through 2028 at least. Even as companies add capacity, it takes time, so supply constraints should persist.

Obviously there's a whole universe of stocks to buy now beyond these three, and honestly the Motley Fool's 10 stocks list is worth looking at if you want professional-grade analysis. Their picks have crushed it historically - Netflix and Nvidia both made that list years ago and delivered insane returns. But these three themes - quantum computing, AI infrastructure networking, and memory chips - feel like they have real legs in 2026 and beyond. Depends on your risk tolerance, but worth thinking about how to deploy that $1,000.
