The art of successful investing often requires looking beyond short-term market movements to identify transformative technological shifts. Rather than focusing on quarterly earnings beats or temporary market sentiment, my investment strategy centers on identifying companies that can compound value over many years or even decades.

The emergence of artificial intelligence (AI) represents such an opportunity. While many view the current AI boom skeptically, the technology's potential to reshape our economy grows clearer by the day.

Industry analysts project AI could add trillions to global gross domestic product (GDP) by 2030, fundamentally altering how we work, create, and solve problems. For long-term investors, this presents a rare opportunity to participate in a technological revolution from its early stages.

As we move into 2025, three companies stand out for their unique positions in the AI value chain. Each brings something different to the table -- from manufacturing the tools that make AI possible to developing the quantum systems that could unlock AI's next chapter. Here's why I plan to aggressively buy these three tech stocks in 2025.

The backbone of AI innovation

ASML Holding N.V. (ASML 1.99%) is the undisputed leader in extreme ultraviolet (EUV) lithography equipment for semiconductor manufacturing. Its stock trades at 27.4 times forward earnings, representing a meaningful premium to the benchmark S&P 500's 24.2 multiple. This premium valuation reflects investors' expectations for continued growth in AI chip demand over the balance of the decade and beyond.

In addition to its core position in the AI value chain, ASML offers a growing income stream with its 0.97% dividend yield, backed by a conservative 35.2% payout ratio. Moreover, the company has increased its dividend at an exceptional 23.4% annual rate over the prior five years, ranking among the highest growth rates in the global stock market.

The bottom line is that ASML represents a compelling opportunity for long-term investors due to its virtual monopoly in lithography equipment for advanced chip manufacturing (which plays a critical role in AI development) and rapidly growing dividend.

The core AI stock

Nvidia (NVDA 4.45%) continues to dominate the AI chip market with its graphics processing units (GPU). Trading at 31.3 times forward earnings, Nvidia commands a healthy premium to the S&P 500, reflecting its position as the primary beneficiary of surging AI adoption. While the current 0.03% dividend yield might seem insignificant, the company's blistering 16.3% dividend growth rate over the prior five years and minimal 1.11% payout ratio signal substantial room for future dividend expansion.

Nvidia's recent quarterly performance underscores its market dominance. Revenue surged 94% year over year in the most recent quarter, marking the sixth consecutive quarter of exceeding guidance by at least $2 billion. The company's GPUs and proprietary software platform have become the de facto standard for AI development, creating powerful network effects and high switching costs for customers.

With AI adoption accelerating across industries and its steadily expanding capital-return program, Nvidia stands out as a foundational holding for AI-focused investors.

A quantum leap forward

IonQ (IONQ 10.84%) stands at the forefront of commercializing quantum-computing technology, though its current market valuation of 233 times trailing sales warrants careful consideration. The company's 237% share-price gain in 2024 reflects broader industry momentum, coinciding with significant developments like Alphabet's Willow chip architecture and Amazon's Quantum Embark initiative.

A key differentiator in IonQ's business model is its cloud-centric distribution strategy. Through partnerships with Microsoft Azure, Amazon Web Services, and Google Cloud Platform, IonQ has created multiple channels for enterprises to access its quantum systems. This integration with established cloud infrastructure reduces technical barriers to adoption and allows for easier scaling of quantum-computing resources as capabilities advance.

However, investors should weigh several critical factors. While IonQ's trapped-ion approach has demonstrated promising coherence times and gate fidelities (i.e., accuracy), the technology still faces significant engineering challenges for practical applications. The company's revenue base remains modest, and achieving commercial scalability requires overcoming both technical and market-education hurdles.

The rapid advancement of AI could accelerate quantum-computing development in unexpected ways. AI's demonstrated ability to solve complex optimization problems and discover novel approaches in fields like chip design and materials science may help overcome current technical barriers in quantum computing. IonQ's market position and deep technical expertise make it well-positioned to benefit from potential AI-driven breakthroughs in quantum-computing architecture and error correction.

Despite widespread skepticism in the investment community, IonQ's commanding lead in quantum-computing technology and strategic cloud partnerships position it to capture outsized value as the quantum-computing market materializes. While the premium valuation may deter conservative investors, those seeking revolutionary technology exposure could find IonQ's risk-reward profile compelling.

The big picture

Computing's future requires three key elements: the manufacturing precision of ASML's EUV machines, Nvidia's AI ecosystem dominance, and IonQ's quantum-computing potential. While their valuations are rich, each company's strong competitive position and expanding opportunities in an increasingly compute-hungry world make them compelling holdings. As a result, I'm increasing my stakes in Nvidia and IonQ and initiating a position in ASML in 2025.
