Will Quantum Computing Stocks Soar in the Second Half?
Quantum computing stocks skyrocketed in 2024, with names such as Quantum Computing and Rigetti Computing surging by more than 1,000%. Investors were eager to get in on what could become the next game-changing technology, and revenue growth as well as scientific progress from some of these quantum specialists boosted optimism. Even after those gains, it's very possible that quantum stocks will climb in the second half of this year, and here's why. Why investors buy quantum computing stocks So, first, a quick note about why investors see so much potential in quantum computing. This is because this type of computing, based on quantum mechanics, makes it possible to solve problems that today's classic computers can't handle. Quantum computing can do this by using qubits -- instead of the bits used by today's computers -- to store data. And while bits store and process data as zeros or 1s, qubits can represent a zero, a one, or both at the same time. This allows for tremendous scaling, and as a result, a problem that would take a classic computer 1,000 years to solve may take a quantum machine about five minutes. Right now, quantum companies offer hardware and services to customers, but we're still in the early stages of development. Experts have said that truly useful quantum computers are several years away. The good news is that this means these companies have plenty of room to run when it comes to revenue growth and share price performance. It's clear that if quantum companies reach their development goals, these computers could revolutionize many industries. Quantum stocks in 2024 and 2025 All of this helped quantum computing pure-play companies climb last year. The bull market and optimism about the economy ahead offered the perfect environment for growth stocks to excel. But in recent months, concerns about President Donald Trump's import tariff plan weighed on these players. The idea was that tariffs could lead to higher prices at home, prompting customers of quantum companies to rein in their spending. But over the past few weeks, progress in trade talks and even initial deals with the U.K. and China have made investors more optimistic about the future. And corporate earnings haven't suggested any slowdown in spending on technology -- in fact, companies continue to reiterate their commitments to such projects. This backdrop supports the idea of more gains for quantum companies in the second half, especially for certain players such as Rigetti and IonQ, which haven't yet fully recovered -- they're down 25% and 5%, respectively, year to date. And if they show some growth in revenue in the coming quarters, this could act as a positive catalyst for share performance, too. Can D-Wave keep soaring? But this doesn't mean that stocks that have continued to advance, such as D-Wave Quantum (NYSE: QBTS), which is heading for an increase of more than 80%, won't keep on rising. For example, D-Wave just recently released its Advantage2 quantum computer, which is accessible both on the cloud and on-premises. More than 20 million customer problems have been run through the prototype, and the company says the computer is now ready for use in areas such as materials simulation and artificial intelligence (AI). Uptake of this new platform and further revenue gains -- D-Wave's revenue last quarter soared 500% to a record $15 million -- could offer this highflier an additional boost. Of course, it's important to keep in mind that these pure-play quantum companies aren't yet profitable and are involved in a relatively new, cutting-edge technology, and that involves some risk. Any economic headwinds could hurt investors' appetite for these sorts of players. These companies depend on a strong economy, as this increases the likelihood that potential customers will spend on their products and services. And investors generally feel more comfortable getting in on growth stocks when the economy is thriving. So, the economic situation in the second half could determine the near-term direction of these players. But right now, there's reason to be optimistic that the U.S. trade talks, along with some better-than-expected economic data, signal better days ahead -- and that the worst-case scenario of a recession and tough times for corporate earnings will be averted. With this in mind, quantum computing stocks could be set to soar in the second half as investors look to get in on the next big technology that could deliver explosive returns.

Better Cybersecurity Stock: CrowdStrike or SentinelOne?
Artificial intelligence (AI) may have many benefits, but it's also making it easier for hackers, online criminals, and other digital malefactors to threaten businesses, and those threats are getting more potent. Keeping them at bay requires a lot of funds to be devoted to cybersecurity, making companies like CrowdStrike (NASDAQ: CRWD) and SentinelOne (NYSE: S) excellent investment opportunities. But is there an advantage to buying one over the other now? How do these two approach cybersecurity? Both companies' base products are AI-powered protection platforms that analyze digital activity and learn to spot the threats among the normal activity. They deploy their software to network endpoints -- in other words, laptops, smartphones, and other devices that can access a client's internal network. By protecting these devices, companies make it harder for cyberattackers to gain access to their internal networks, where they might steal sensitive information, delete files, interfere with systems, or even lock them down with ransomware to extort payments from their victims. While endpoint protection is how both companies land clients, each bolsters its offerings with an array of other cybersecurity products that clients can use to create a protection suite tailored to their unique situations. Since these two direct competitors offer highly similar product types, it's hard to declare either a winner on this front from an investor perspective. Winner: Tie. CrowdStrike is much larger than SentinelOne From a sheer size perspective, CrowdStrike is the clear winner. During its fiscal 2026 first quarter, which ended April 30, CrowdStrike's annual recurring revenue (ARR) rose to $4.4 billion. SentinelOne's ARR of $948 million in its fiscal Q1 was less than a quarter of that. While size doesn't always matter, in this case, it does. Because so many more companies use CrowdStrike's platform, it's more likely that any given IT professional will have at least one contact already on its client list. If CrowdStrike is doing a great job with those clients, word will spread, and it will likely receive more serious consideration in future cybersecurity bidding processes. This advantage cannot be understated. Indeed, it's one of the reasons why CrowdStrike's growth has remained strong despite its size. Winner: CrowdStrike SentinelOne is growing more quickly than CrowdStrike, but just barely In terms of growth rates, SentinelOne is slightly outperforming CrowdStrike in this category. However, this should be no surprise because SentinelOne is a much smaller company. In fiscal Q1, SentinelOne's ARR rose 24% year over year, while CrowdStrike's increased 22% year over year. While I will give the point to SentinelOne, it's important to understand that CrowdStrike is growing from a much larger base than SentinelOne, making this close call all the more impressive for CrowdStrike. Winner: SentinelOne Neither company is massively profitable Due to its smaller size and focus on top-line growth, SentinelOne is far from profitable, while CrowdStrike has achieved intermittent profitability (although it reverted to a negative operating margin and a loss in its most recent quarter). S Operating Margin (Quarterly) data by YCharts. SentinelOne is far from breaking even, but CrowdStrike was in this same position about five years ago. There's no reason not to expect SentinelOne to follow a similar path to profitability, but it will take some time. Meanwhile, CrowdStrike should eventually turn a profit again, as it has proven that it can do that. Winner: CrowdStrike SentinelOne looks like a bargain CrowdStrike is leading this battle of the stocks so far, but SentinelOne is about to change the narrative with one jaw-dropping metric. CrowdStrike is the most popular cybersecurity stock in the market, and as a result, it has been bid up to expensive levels. From a price-to-sales (P/S) standpoint (the best metric to use to compare these companies since CrowdStrike flips between profitable and unprofitable, while SentinelOne is years away from profits), CrowdStrike has gotten far more expensive than SentinelOne over the past few years. S PS Ratio data by YCharts. CrowdStrike stock is now five times more expensive than SentinelOne, which is hard to believe, considering they compete in the same industry and are growing at nearly identical rates. This leads me to believe that CrowdStrike's stock has been overly hyped up while SentinelOne has been forgotten. While I'm OK with valuing CrowdStrike at a premium due to its market leadership position, this is far too great a premium to pay. SentinelOne is a dirt-cheap stock, and CrowdStrike is almost too expensive to consider. While I have been a long-term CrowdStrike bull, I'd be a bit cautious about buying the stock at its current lofty valuation. As a result, I think SentinelOne is the better cybersecurity investment right now. Should you invest $1,000 in CrowdStrike right now?

Is Cathie Wood Actually Right About Tesla Stock?
Cathie Wood's Ark Invest has been one of the most vocal supporters of and investors in Tesla (NASDAQ: TSLA), and it's no secret in the investing world that Ark has a $2,600 price target on the stock for 2029. Still, what does that target mean, and does Ark's reasoning make sense? Here's the lowdown. Ark Invest's $2,600 price target The investment company's price target won't be "right," but then again, it's not supposed to be. It's an expected case scenario produced by a Monte Carlo simulation. In other words, Ark plugged numerous variables into an algorithm and ran a vast number of computer simulations to model a range of randomized outcomes. It's not necessary to get into the weeds about how these simulations are done; suffice it to say that on the bearish side, Ark's model shows a 25% chance that Tesla's stock price will be $2,000 or less in 2029, and on the bullish side, it finds a 25% chance that it will be $3,100 or more. Roughly in the middle lies Ark's expected value of $2,600 for the shares. Where to invest $1,000 right now? Our analyst team just revealed what they believe are the 10 best stocks to buy right now. Continue » The modeling itself is almost certainly wrong, simply because it relies on variables that are incredibly hard to predict. To illustrate just how challenging it can be to make accurate stock forecasts using this kind of simulation, let's revisit the predictions Ark made in 2021 and 2023 for Tesla's share prices in 2025 and 2026, respectively. Tesla's current stock price in 2025 is about $320. Data source: Ark Invest presentations. Tesla's stock price is currently far below even the bearish scenario Ark simulated in 2021, and it would have to increase by 806% to hit the bear case scenario for 2026 that was projected in 2022. All of which is not to criticize Ark, because modeling the long-term value of a speculative growth stock like Tesla is incredibly difficult. The point is not to take the targets too literally. But if investors can't take such price targets as gospel, is there anything to be gleaned from Ark's analysis? As a matter of fact, there is. Where Ark's model makes sense The key points from the model that investors can take away are the following: Tesla's share price is highly sensitive to the timing and scaling of its robotaxi and Full Self-Driving (FSD) capabilities. The $2,600 price target for 2029 assumes that at that point, 88% of Tesla's enterprise value (market cap plus net debt) will be attributable to its robotaxi business, and just 9% to its electric vehicle (EV) sales. The message is clear: Don't buy Tesla stock unless you believe there's a good chance its robotaxi service (which may already be operating in its first market by the time you read this) won't be successful. Everything is riding on the company's robotaxi bet. Tesla's robotaxis Tesla's unsupervised Full Self-Driving (FSD) system is unproven, as is its robotaxi concept. Notably, it has yet to begin volume production of its dedicated robotaxi, the Cybercab. Moreover, there are myriad regulatory hurdles and safety concerns to overcome. Simply put, Tesla's robotaxi business is risky. And if it fails, it will likely set Tesla back significantly. Buyer beware. That said, while Tesla is a speculative growth stock -- remember, buyers at this point are investing primarily for its robotaxi business, not its electric vehicle business -- it's a growth stock with a difference. Tesla continues to dominate the EV market, and rivals such as Ford Motor Company and General Motors, have withdrawn from the robotaxi race. The auto industry as a whole has invested billions into the various efforts to develop a fully autonomous vehicle, and Tesla has not been alone in overpromising and underdelivering on it. Yet Tesla is launching its robotaxi service, and it has the vehicles, the data hoard, and the cash reserves to make it work. It's also ideally placed to start producing lower-cost EVs (which can be used as robotaxis controlled by unsupervised FSD systems), and the company says it's set to begin volume production of the Cybercab in 2026. Where Wood might be right Ark Invest is correct that the robotaxi business will be the key to Tesla's longer-term valuation and also the future of the auto industry. If -- and it's a big if -- Tesla can get the technology right, then there's significant upside for the stock, because all the other operational ingredients are in place for the company to make it work. That's where Wood and Ark might be right after all. 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 $373,066!* Apple: if you invested $1,000 when we doubled down in 2008, you'd have $38,158!* Netflix: if you invested $1,000 when we doubled down in 2004, you'd have $664,089!* Right now, we're issuing 'Double Down' alerts for three incredible companies, available when you join Stock Advisor, and there may not be another chance like this anytime soon.
