This Is the Most Promising Quantum Computing Stock, but Should You Buy It Right Now?

Quantum computing has the potential to accelerate how companies and scientists process data, which could lead to more advanced artificial intelligence, better weather predictions, and medical breakthroughs.

The long-term potential for quantum computing stocks is significant, and McKinsey estimates the market could reach up to $2 trillion by 2035.

Competition is already heating up, with many companies taking a unique approach to developing their quantum computers. One such company is IonQ (NYSE: IONQ), a leading manufacturer of quantum computing systems. But is the stock a buy right now? Let's take a closer look.

Why IonQ is so promising

One thing that makes IonQ unique is its quantum computer creation method. Instead of using more traditional quantum computers that include "loops of supercooled superconducting wire or intentional imperfections crystalline silicon," IonQ uses trapped ions instead.

The company says the trapped ions can be used to create a linear chain of ions that can be used for quantum processors with the potential for 100+ qubits (the unit of processing measurement for quantum computers). The result is a high-powered quantum computer with the potential for far fewer errors than the competition.

One of the biggest hurdles for quantum computing is using it for practical purposes. However, IonQ is already growing its customer list, with the automaker Hyundai, industrial equipment company Caterpillar, and the U.S. military as customers.

IonQ's management said in the recent quarterly earnings call that biopharmaceutical drug discovery and computer-aided simulations for the engineering and manufacturing industries are two of the company's primary focuses for practical quantum computing applications. The company recently tapped into some of this market potential by announcing a new partnership with AstraZeneca to speed up innovation in biopharmaceuticals.

IonQ also offers access to some of its quantum computing via public cloud networks, including Microsoft, Amazon, and Alphabet's Google. These partnerships could help further practical uses of its quantum computer processing as demand grows.

IonQ isn't a buy right now

Even with its significant potential in quantum computing, I don't think IonQ's stock is a buy right now for most investors.

First, quantum computing is highly speculative. Sure, there are some practical applications, but investing in this technology is essentially a bet that quantum computing will one day significantly change how companies process information. It's an unproven market, and trying to pick a winner so early seems nearly impossible.

Second, and perhaps most importantly, IonQ's stock is pricey right now. Its shares have a forward price-to-sales ratio of 217. After share price gains of more than 250% over the past 12 months, IonQ's stock is trading at a premium. Meanwhile, its revenue is still modest, and losses are significant.

Sure, third-quarter revenue more than doubled, and the company exceeded its revenue guidance up to $12 million for the quarter, delivering $12.4 million instead. But that figure pales in comparison to IonQ's net loss of $52.5 million.

While IonQ is making progress with increasing its sales and expanding partnerships, there's still a lot of uncertainty in quantum computing, and the company's losses are significant. Given that we're still at the beginning of this nascent market, any investment in a quantum computing pure play is risky.

Instead, investors may want to look at other tech companies, like Alphabet, that are making significant gains in quantum computing but also have greater financial stability.

Don’t miss this second chance at a potentially lucrative opportunity

Ever feel like you missed the boat in buying the most successful stocks? Then you’ll want to hear this.

On rare occasions, our expert team of analysts issues a “Double Down” stock recommendation for companies that they think are about to pop. If you’re worried you’ve already missed your chance to invest, now is the best time to buy before it’s too late. And the numbers speak for themselves:

• Nvidia: if you invested $1,000 when we doubled down in 2009, you’d have $381,744!*
• Apple: if you invested $1,000 when we doubled down in 2008, you’d have $42,357!*
• Netflix: if you invested $1,000 when we doubled down in 2004, you’d have $531,127!*

Right now, we’re issuing “Double Down” alerts for three incredible companies, and there may not be another chance like this anytime soon.
