AI is arguably positioned to be the highest-growth industry over the next decade. It’s the largest sector in which I own shares, and there are two specific artificial intelligence (AI) stocks to consider buying for my portfolio that I believe could be highly profitable investments over the long term.

TSMC

Taiwan Semiconductor Manufacturing Company (NYSE:TSM) is a semiconductor foundry that provides production services for almost all of the AI companies in the world. Its customers including Nvidia, Telsa and Google, among many others.

Should you buy ASML shares today?

Before you decide, please take a moment to review this report first. Despite ongoing uncertainties from US tariffs to global conflicts, Mark Rogers and his team believe many UK shares still trade at substantial discounts, offering savvy investors plenty of potential opportunities to learn about.

That’s why this could be an ideal time to secure this valuable research – Mark’s analysts have scoured the markets to reveal 5 of his favourite long-term ‘Buys’. Please, don’t make any big decisions before seeing them.

The company is so significant in the semiconductor supply chain, particularly for advanced chips related to AI, that it has even been the cause of tension between China and the US. This is one of the biggest risks for the shares, I feel. It’s also the core reason why I’m not investing aggressively in the firm.

My investment in TSMC is up 49% at the time of this writing since I bought it in October 2023. Its net margin is in the top 3% of companies in the semiconductor industry. It has largely driven this by the extensive ‘moat’ it has. Customers can’t find the kind of extensive production services it has elsewhere.

This is my number one choice. I just have to be willing to bear the risk associated with international politics at the moment. While I’m simply holding the portion I already own at this time, I may buy more in the future.

ASML

ASML Holding (NASDAQ:ASML) produces the equipment vital for semiconductor manufacturing. Therefore, the company is considered one of the most crucial elements in the development of AI. Combined with TSMC, it provides exposure to the foundational building blocks of the AI industry — production.

Interestingly, its biggest customer is TSMC, accounting for a massive 38% of its total revenue. Additionally, it sells its manufacturing equipment and maintenance services to Samsung and Intel, among many others. It’s the largest semiconductor manufacturing equipment provider on the planet.

My investment in ASML is up 27.5% at the time of this writing since I bought it in December 2023. However, I’m unsure about the firm’s valuation at the moment. After all, it has a price-to-earnings (P/E) ratio of 44, which is high. This is a risk to me, but I view it as trading at a fair price (rather than being overvalued) based on its significance in AI at the moment.

This is my second-best choice, and as long as I’m comfortable holding it with such a high valuation, I can see myself keeping this company in my portfolio for decades. However, I’m diversifying away from technology for protection from global tensions around semiconductors at the moment. I’m holding the portion I already own for now but may buy more later.

My takeaway

To really be a true investor in the AI revolution, I think it’s best to start at the most basic level. If I can own a piece in the production of semiconductor chips that drive these new advanced technologies that could change the world, I think I’m off to a good start.
