The Oracle of Omaha focuses on companies with strong economic moats and undervalued assets, applying his well-known investment strategy – long-term value investing. Buffett is not that fond of diversification, as he is investing in businesses instead of stocks, picking those he understands.
While diversification as a risk mitigation technique is popular among those who are at the start of their investing journey, Buffett believes diversification could limit knowledge. He also doesn’t consider money the greatest investment tool, given his statement that “the best investment by far is anything that develops yourself, and it’s not taxed at all.”
Despite the strong market performance throughout much of 2024, Buffett appears to have taken a more cautious approach. With overinflated valuations due to high interest rates and deteriorating economic conditions in mind, he opted to sell off substantial stakes in companies whose valuations have become too high.
Buffett is also not fond of President Donald Trump’s tariffs on imports that sent shockwaves through global stock markets, even though his company’s Class B shares dipped 1.4% only on April 3, outperforming the broader market.
In the fourth quarter, Buffett’s 13F portfolio was comprised of a total of 38 security holdings and was worth roughly $267 billion, slightly up from $266 billion in the third quarter. Given that Buffett doesn’t like to diversify much, his top ten holdings account for nearly 90% of his 13F portfolio.
