Berkshire Hathaway chairman and former CEO Warren Buffett, known for playing the long game with investing

Billionaire investor Warren Buffett hasn’t been known for chasing hot tech trends.

In fact, a large part of the success of Buffett’s holding company, Berkshire Hathaway, comes from disciplined value investing. Since the 1960s, Berkshire Hathaway’s MO has been to scoop up high-quality companies at a discount (think Coca-Cola or Bank of America) and hold them for decades.

That’s what makes a recent shift in Berkshire Hathaway’s portfolio (1) eye-catching.

Today, a massive 20.4% of Berkshire’s roughly $300 billion stock portfolio is in just three tech companies that all share one trait: They’re at the epicenter of the artificial intelligence boom.

Granted, these three names — Amazon, Google, and Apple — are Big Tech players with diversified business models, but the fact that Berkshire is putting billions into this cutting-edge space signals a shift from their standard playbook.

Berkshire’s new CEO, Greg Abel, and his team seem perfectly comfortable placing a ton of cash into the AI narrative.

So, if one of the most value-focused investing giants is leaning this hard into AI, does that make AI investing unavoidable?

AI meets the modern investment portfolio

While Berkshire Hathaway’s bet on AI powerhouses may seem surprising given the firm’s reputation for avoiding stock market trends, it’s not all that shocking when looking at broader market trends.

The fact is that pretty much everyone nowadays is investing in AI, even if they think they’re already “diversified.”

Research from RBC Wealth Management (2) called this the “Great Narrowing,” noting that the S&P 500’s top 10 companies now account for 40.7% of its weight.

Not only is that a huge concentration compared to years past, but RBC analysts also note that all of these companies have deep ties to AI.

So, even if investors want broad exposure to the U.S. market, a big chunk of their S&P 500 funds relies on AI’s sustained outperformance.

Should you bet with Berkshire?

Whether you agree with Berkshire’s high exposure in AI or you fear the valuations are a bit frothy, everyone can take a few notes from the firm’s overall strategy to make more informed investment decisions.

Rather than focusing on specific names, look into what kinds of investments Berkshire Hathaway tends to make that have made it such an outperformer over the decades.

For starters, focus on quality. Berkshire’s approach to AI suggests it’s wiser to invest in a few dominant companies with diversified business models rather than YOLOing, taking the you only live once approach into unproven startups.

Second, look for staying power. Companies with solid fundamentals and hard-to-replicate ecosystems can ride out short-term “hype cycles” if AI enthusiasm wanes.

Lastly, just because AI is the hot investment idea doesn’t mean it has to be the centerpiece of every portfolio. Even with its AI bets, Berkshire still has plenty of diversification with massive positions in brands like Mitsubishi, American Express and Chevron.

However you choose to invest, keeping Berkshire’s principles in mind can help create a portfolio you feel comfortable about for the long haul.
