Been looking at where to park $1,000 in the market right now, and honestly, the setup feels pretty solid for the next few years. S&P 500 is up 94% since late 2022, and major banks are still bullish - Deutsche Bank's calling for 8,000 by year-end, Goldman expects another 12% rally. So the question becomes: which sectors are actually going to drive those gains?

I keep coming back to three areas that seem like must buy stocks for anyone looking to position ahead of the curve. First up is quantum computing, which everyone talks about but most people don't really understand yet.

IonQ is the play here if you want exposure to that space. Yeah, it's tiny compared to traditional tech, but McKinsey projects the quantum market explodes from $4 billion now to $72 billion by 2035. IonQ's revenue more than doubled in the first nine months of 2025 - we're talking $68 million with Q3 alone jumping 222%. That's the kind of growth trajectory that gets my attention.

What's wild is their technical progress. They hit a world record 99.99% accuracy on their quantum systems last October, which basically means their machines are almost error-free. Cost per system is supposedly 30x cheaper than competitors. The valuation is spicy at 158x sales, no question, but if quantum actually takes off like everyone expects, even a small allocation could pay serious dividends. The volatility is real though - this isn't a buy and forget situation.

Now here's where things get more concrete. AI infrastructure spending is actually happening right now, not someday. Gartner's calling for 41% growth in AI spending this year alone, hitting $1.4 trillion. That's real money flowing into real companies.

Celestika is one of those beneficiaries. They design and manufacture the networking components that go into AI accelerators from Broadcom, AMD, Intel, and others. Plus they build the rack-scale solutions for hyperscalers deploying AI data centers. Revenue jumped 27% in 2025 to $12.2 billion, and the forecast shows acceleration ahead. Stock's trading at 3.2x sales - that's genuinely cheap for a company growing like this. These must buy stocks in the infrastructure space don't come around often at these valuations.

Micron is the other one I keep watching. Memory chips are basically the bottleneck right now. Demand's crushing supply, prices are up, and that shortage probably runs through 2028. Micron's trading under 10x sales with forward earnings at 11x - both dirt cheap. Their earnings could jump 4x this fiscal year on 100% revenue growth. Yeah, they had a monster 243% run last year, but the fundamentals actually support going higher. Memory chip shortage means sustained pricing power.

So if you've got $1,000 sitting around after handling your debt and emergency fund, you could split it three ways or go heavier on the infrastructure plays depending on your risk appetite. Quantum's the lottery ticket. Celestika and Micron are the more tangible bets on AI buildout that's already underway. All three look like must buy stocks to me if you're positioning for 2026 and beyond, but obviously do your own homework on valuation and risk tolerance.
