Why Focus On AI Stocks Now?

The Future of AI Spending Is Just Beginning

The AI industry is expected to see exponential growth in the coming years, with AI applications transforming cloud computing, chip manufacturing, software productivity, and more.

Despite potential overvaluations in some areas, foundational AI players are still attractive long-term bets.

What Makes A Top AI Stock?

To be a top-tier AI investment, a company needs:

• Strong revenue growth

• An identifiable competitive advantage

• Robust R&D and capital expenditures

• Solid positioning within the AI infrastructure or application layers

Let’s explore three AI stocks that check all the boxes.

Alphabet: Defying The AI Skeptics

AI Integration In Core Search

While some feared that chatbots would displace Google Search, Alphabet has proven otherwise. Search revenue climbed 12% YoY last quarter, up from 10% the quarter before, thanks to generative AI integration.

Features like AI Overviews, Circle to Search, and Google Lens are increasing engagement and search traffic.

Google Cloud: The Real Growth Engine

Alphabet’s Google Cloud posted 32% revenue growth in the last quarter. Even more importantly, it expanded operating margins from 11% to 21% year-over-year.

The company increased its annual capex guidance to $85 billion, largely aimed at supporting cloud and AI infrastructure.

Regulatory Overhang & Opportunity

While Alphabet faces legal pressure regarding monopolistic practices, shares trade at just 20x forward earnings, making it the cheapest Magnificent Seven stock.

The price reflects regulatory concerns, but it also presents a compelling opportunity given the underlying growth.

Microsoft: A Dual AI Powerhouse

Cloud & Productivity AI At Scale

Microsoft made a strategic bet on OpenAI in early 2023, becoming both a customer and collaborator through its Azure cloud services.

Azure has since become a $75 billion business, growing revenue by 34% year over year in fiscal 2025. In the most recent quarter, Azure accelerated further with a 39% YoY growth.

Microsoft also recently shared the top occupations with the highest AI applicability score:

Capex Surge Backed By Demand

Microsoft’s heavy investments in infrastructure continue, with capital expenditures projected at $30 billion this quarter, up from $24 billion last quarter. Still, the demand justifies the spend.

Remaining performance obligations rose 35%, and management expects 37% growth in Azure in the upcoming quarter.

AI Embedded Across The Ecosystem

Beyond cloud, Microsoft’s Copilot AI assistants are now integrated across its software suite, driving higher monetization per user.

The introduction of Copilot Studio lets enterprises build custom AI agents using proprietary data and OpenAI’s foundation models. This has helped the Productivity and Business segment grow 16% last quarter.

Taiwan Semiconductor Manufacturing: The AI Supply Backbone

The World’s Most Important Chipmaker

TSMC manufactures the cutting-edge semiconductors that power AI infrastructure. With customers like Nvidia, Apple, Microsoft, and Alphabet, it commands over two-thirds of all contract semiconductor manufacturing.

Technology Moat & Virtuous Cycle

TSMC’s leadership in advanced nodes (like 2nm chips) creates a self-reinforcing cycle: the most advanced chip designs go to TSMC, which reinvests in R&D and capacity to maintain its lead.

Going forward, the company forecasts 20% average annual revenue growth, recently upgraded to 30% for 2025 after strong Q2 performance.

Pricing Power & Margin Strength

Despite capital expenditures nearing $40 billion, gross margins remain near 60%. With robust pricing for next-gen nodes, TSMC looks poised to maintain high profitability.
