Are you looking beyond the market's current (and mostly bearish) volatility and into the long-term future? If so, good! Just a few years from now, 2022's turbulence will be a faded memory, with some stocks likely to be valued much higher then. That's just the way things work: one step back, followed by two steps forward.

Here's a closer look at two long-term growth stocks you may want to step into now while they're on sale. They're not likely to remain at these discounted prices for a whole lot longer.

1. Nvidia

You may know it as a video gaming hardware company, but Nvidia (NVDA -3.01%) is so much more. Its graphics processing units, or GPUs, are powerful computing hardware capable of handling tasks ranging from artificial intelligence (AI) computations to cryptocurrency mining to heavy-duty industrial visualization.

All of these markets are at least somewhat cyclical, which is the key reason Nvidia shares are down by more than half from their late-2021 peak value after a more than 1,000% run-up from 2019's lows. Not only did the early part of this period mark crypto's mining heyday, but it was also the artificial intelligence movement's critical mass. Both manias are cooling off now, with AI's presumed slowdown being largely linked to waning economic strength.

This stock's sellers, however, have arguably overshot their target.

See, none of these markets are ever going away. They're just cyclical, with each rebound usually driven by a technological evolution. The crypto mining craze's hottest days may all be in the past. But Nvidia's graphics processing tech is still needed to handle the underlying blockchain that is helping the world get -- and keep -- a handle on things like payment processing and logistics.

In the meantime, the AI market may be far more resilient than you think.

While economy-minded budget cuts may be crimping some technology investments, tech market research and consulting outfits like Forrester Research and International Business Machines recommend maintaining investments in artificial intelligence despite their cost. As it turns out, these investments are more than paying for themselves by finding inefficiencies and producing new types of actionable data that ultimately widen profit margins by saving money. To this end, International Data Corp. estimates the AI market will grow at an average annual pace of nearly 19% between now and 2026. It matters simply because artificial intelligence is now regularly rated as Nvidia's biggest profit center, depending on the quarter.

Could Nvidia shares stumble in the foreseeable future? Sure. This fiscal year's revenue is projected to be flat, dragging earnings 24% lower. Coming up short of those already-lowered expectations could easily upend the stock.

However, none of the company's long-term potential is reflected in the stock's recent weakness, and the long-term could begin sooner than you'd expect. Revenue is expected to start growing again to the tune of 13% next fiscal year, driving per-share earnings almost back to last fiscal year's bottom line as a result. That's a great start.

2. Shopify

Kudos to Amazon for updating policies that alienated many of its third-party sellers. But, the underpinnings of that tension are still in place. Small merchants and brands want more control of their customers' online shopping experience in addition to wanting to keep more of their sales revenue. And it's not just Amazon. eBay and other e-commerce platforms are no longer working out well enough for their sellers either.

Enter Shopify (SHOP -0.31%).

Shopify offers consumer-facing businesses a suite of e-commerce solutions. Allbirds, Staples, Jenny Craig, and Dressbarn are just some of the estimated 2 million brands using a Shopify-powered store to connect directly with customers who collectively purchased $46 billion worth of goods during the third quarter of this year alone. That's a 10% year-over-year improvement, extending a lengthy top-line uptrend.

And yet it's still only a fraction of the potential market. eMarketer forecasts the global e-commerce market will grow to $5.5 trillion this year, and that figure still only accounts for about a fifth of the total retail market.

Investors keeping tabs on Shopify most likely know the stock's down roughly 80% for the past year, peeling back from a 2020/2021 rally linked to the COVID-19 pandemic when online shopping became even more common. In retrospect, it's clear now that investors expected too much, too soon.

As was the case with Nvidia, however, the depth of Shopify's current sell-off doesn't make sense. Analysts still expect this year's revenue growth of nearly 24% to remain a healthy 21% next year as merchants and brands continue expanding their use of the internet to connect with customers. That strongly suggests the stock is worth a closer look.
