Four Top Stocks for Long-Term Investment

Four Top Stocks for Long-Term Investment

Investment in artificial intelligence (AI) is expected to see significant growth over the next five years. Capital spending on AI by major companies continues to rise, creating opportunities for firms involved in AI infrastructure development.

Nvidia (NVDA), Broadcom (AVGO), Micron (MU), and Taiwan Semiconductor Manufacturing (TSM) are four companies poised to reap substantial benefits from this trend. All four have stakes in the growth of AI-driven data centre spending.

If AI spending continues to rise as projected, these four companies could deliver significant returns.

The figure often cited for AI capital spending is $650 billion, but this only covers the four largest hyperscale AI companies. It does not include other major AI players, private firms like OpenAI or xAI, or spending in China and other regions worldwide. Therefore, this figure could potentially rise to nearly $1 trillion this year.

McKinsey & Company estimates cumulative AI spending will reach $7 trillion by 2030. Meanwhile, Nvidia projects global data centre capital spending will increase to $3 trillion to $4 trillion per year by 2030. Both projections indicate vast potential in AI infrastructure investment.

Stocks Poised for Takeoff

Nvidia is the top choice for AI investment due to its position as the world’s most popular provider of AI computing units.

Demand for Nvidia’s products is extremely high and expected to continue. The company’s revenue rose 73% in the fourth quarter (ended 25 January) and is projected to increase by 77% in the first quarter. Nvidia remains the market leader, with everyone from hyperscale AI firms to individual developers wanting to use Nvidia chips. With a valuation of 22 times estimated earnings, Nvidia is one of the best investment options currently.

Broadcom

Broadcom competes with Nvidia through partnerships with hyperscale AI firms to design custom AI chips. This approach allows end-users to tailor chips to workloads, improving efficiency. While it cannot fully replace GPUs, these custom chips have a niche market. In the first quarter of fiscal 2026 (ended 1 February), Broadcom’s AI semiconductor division grew 106% to $8.4 billion. The AI chip business within this division grew even faster, at 140%.

Broadcom targets more than $100 billion in revenue from AI chips by the end of 2027. This indicates that Broadcom will become an increasingly important player in AI computing in the coming years.

Taiwan Semiconductor Manufacturing

Taiwan Semiconductor Manufacturing (TSMC) is a chip foundry that will benefit from rising AI spending. With market projections showing increased AI spending through 2030, TSMC is well-positioned to capitalise on these opportunities.

Micron

Micron produces memory chips. With supplies of memory chips tightening, prices of its main products have surged. This has led to significant revenue growth for Micron, which is expected to continue.

The total potential market for high-bandwidth memory (HBM), used in AI, is projected to grow from $35 billion in 2025 to $100 billion in 2028. The current shortage of memory chip supply is not expected to improve anytime soon. This is a positive sign for Micron’s stock, which is anticipated to perform well over the next five years.
