Best AI Stocks to Buy: Smart Artificial Intelligence Investments (2024)

Nvidia

• Market value: $2.65 trillion
• Dividend yield: 0.04%

One of the best stocks to buy to gain exposure to AI is Nvidia (NVDA, $108.10). The company is the pioneer in GPUs, which provide for immersive graphics. But the technology has also proven effective for advanced AI models. A big reason is that GPUs can process a huge amount of data in parallel.

As for Nvidia, the company was smart to invest heavily in the AI market. The result is that its GPUs are the standard.

But the success for one of Wall Street's best AI stocks is more than sophisticated chips. NVDA has the Cuda software development system and various AI libraries. Because of this, the company has a global ecosystem of AI researchers and developers. According to one study, Nvidia GPUs are cited 19 times more than rival chipmakers in academic papers.

"We view NVDA as *the* AI company: a sustainable leader in massive parallel and heterogeneous compute chips, software, and recently services, to enable AI & related applications," says Truist Securities analyst William Stein (Buy). The analyst adds that Nvidia's leadership in the space is driven by "its culture of innovation, ecosystem of incumbency, and massive investment in software, AI models, and services, that we believe makes its chips a default choice for most engineers building AI systems."

Demand for Nvidia's chips is certainly seen in its top line. In its second-quarter earnings report, the company said revenue was up 15% quarter-over-quarter and more than doubled year-over-year. And its data center revenue surged 154% from the year-ago period thanks to AI.

For investors looking at a long-term play on artificial intelligence, NVDA looks like a winner among semiconductor stocks.

Microsoft

• Market value: $3.08 trillion
• Dividend yield: 0.7%

In early 2023, Microsoft (MSFT, $414.20) CEO Satya Nadella said, "The next major wave of computing is being born, as the Microsoft Cloud turns the world's most advanced AI models into a new computing platform."

A big boost has definitely come from OpenAI. All told, Microsoft has invested roughly $13 billion in the company. This partnership has helped fuel MSFT's AI initiatives – and boost its top and bottom lines.

Indeed, in its most recent earnings report, MSFT disclosed year-over-year earnings growth of 10%, while revenue was up 15%.

While CFRA Research analyst Angelo Zino admits that Microsoft's quarterly results indicated a deceleration in growth for the company's cloud platform, Azure, he expects revenue to reaccelerate in the new fiscal year. He's also upbeat about MSFT's AI prospects in both the cloud and software-as-a-service (SaaS), as well as its ability to efficiently manage higher spending.

Zino has a Strong Buy rating on the Dow Jones stock and a $490 price target, representing implied upside of 18% to current levels.

SentinelOne

• Market value: $6.9 billion
• Dividend yield: N/A

A recent Gartner survey of chief information officers shows that cybersecurity is the top priority for companies. About 80% of the respondents indicated that they planned to increase spending on this technology this year.

This really should be no surprise. The cyber-threat environment is getting more dangerous and brazen.

But AI can help. In real time, it can detect harmful intrusions and remediate them.

One of the best AI stocks for cybersecurity is SentinelOne (S, $21.64). Founded in 2013, the company has built the Singularity XDR Platform. Think of it as an autonomous security system. It monitors endpoints, cloud workloads, IoT (Internet-of-Things) and cloud containers for potential threats. The system will then quickly fix the problems.

And the growth for the cybersecurity stock has been strong. For the latest quarter, the company reported a 33% year-over-year jump in revenue to $198.9 million and the number of customers with annual recurring revenues of over $100,000 rose by 24% to more than 1,200.

Palantir Technologies

• Market value: $77.8 billion
• Dividend yield: N/A

In the early days of PayPal (PYPL), the company almost failed because of the rampant fraud on the platform. But cofounder and CEO Peter Thiel implemented sophisticated analytics and AI to mitigate the problems. These systems worked extremely well and PayPal would eventually sell to eBay (EBAY) for $1.5 billion in 2002.

Thiel realized there were other applications for the AI technology, such as for systems to detect terrorism or threats on the battlefield. He took part of fortune from the PayPal windfall and created Palantir Technologies (PLTR, $34.76).

While the government would remain important for Palantir – especially with the wars in Afghanistan and Iraq – the company has since diversified into commercial markets. They span industries like healthcare, energy and manufacturing.

At the heart of this is the Foundry system. Palantir considers it an operating system for an organization's data. The system also helps to create, deploy and manage AI models. For example, Tyson Foods (TSN) has realized $200 million in annualized savings over a 24-month period.

In its fiscal second quarter, Palantir reported a 27% year-over-year increase in revenue to $678 million and the customer count grew by 41%. The company also said adjusted free cash flow (AFCF) was $149 million, marking the 11th straight quarter that AFCF was positive.

Duolingo

• Market value: $7.5 billion
• Dividend yield: N/A

Back in 2009, a Carnegie Mellon University professor, Luis von Ahn, as well as one of his students, Severin Hacker, came up with the idea for Duolingo (DUOL, $173.28). They wanted a much more affordable way for people to learn languages. This was something that von Ahn experienced while growing up in Guatemala.

The timing was fortuitous because of the emergence of mobile platforms from Apple and Alphabet (GOOGL). The founders also were prescient in leveraging AI models.

The company has used this technology for all the key parts of the Duolingo system. These include curriculum design, raw content creation, exercise creation and lesson personalization.

However, this is not to imply that everything is automated. Duolingo blends human expertise with its AI platform. This is especially the case with curriculum design, which must abide by high-levels of educational standards.

A key competitive advantage is Duolingo's enormous data set. This is the benefit of having 97 million MAUs (monthly active users) and 31 million daily active users (DAUs).

To generate revenue, the company relies on a freemium model. The core app is free and there are paid options for additional features. In the most recent quarter, the company announced a 45% year-over-year increase in revenue to $167.6 million and 54% growth in paid subscribers to 7.4 million.

And considering there are roughly 1.5 billion language learners across the globe by some estimates, there's certainly lots of room for more growth for one of Wall Street's best AI stocks.

Snowflake

• Market value: $37.5 billion
• Dividend yield: N/A

Traditional databases were not built for the complex requirements for AI. So yes, there have emerged next-generation solutions.

A standout is Snowflake (SNOW, $110.27). The founders of the company were veterans from companies like Oracle (ORCL). In other words, they understood the limitations of legacy database technology. With Snowflake, the approach was to start from scratch.

This meant creating a database in the cloud, which would allow for easily scaling the workloads. The founders also made sure that it was easy for users to get started. Spinning up a database took only a few minutes. Then there was strong governance and security infrastructure.

Snowflake has certainly become an effective tool for AI projects. The technology has also been a source of strong growth. In its latest quarter, Snowflake posted a 29% year-over-year increase in revenue to $868.8 million and the net revenue retention rate was 127%. There are 10,249 total customers and 510 had 12-month trailing revenue of over $1 million.

The market opportunity for Snowflake is enormous, estimated to be about $248 billion. This is great news for investors seeking out the best AI stocks to buy now.

iRhythm Technologies

• Market value: $2.3 billion
• Dividend yield: N/A

It is estimated about 1.5% to 5% of the U.S. population suffers from cardiac arrhythmia. The most common type is atrial fibrillation (AFib), which was the cause of more than 28,000 deaths in 2021, according to the Centers for Disease Control and Prevention (CDC).

But there are innovative wearable devices that can help. A leader in this category is iRhythm Technologies (IRTC, $72.41). The company is the developer of the Zio monitor, a small and comfortable device that detects and diagnoses irregular heart rhythms.

An essential part of this is a powerful AI system that is based on a sophisticated deep neural network with 34 layers. It has been trained on over 5 million patient records and more than 1 billion hours of curated heart-beat data. "Zio by iRhythm has the only FDA-cleared deep learned algorithm that detects 13 types of arrhythmia classes in this space that has been included as part of the CPT code validation process," the company explains.

"Zio by iRhythm utilizes AI for classifying and characterizing diverse heart rhythms, including atrial fibrillation or AFib," said Evangelos Hytopoulos, the senior director of data science at iRhythm Technologies. "iRhythm's deep learned algorithm has been clinically proven to be as accurate as expert cardiologists."

While IRTC has had operational issues that have hampered growth, it appears to be turning a corner. In the latest quarter, the company posted a 19.3% year-over-year increase in revenue to $148.0 million. It also raised its full-year forecast. Investors would be wise to keep IRTC on their list of the best AI stocks.
