Warren Buffett's Berkshire Hathaway has become the first non-tech U.S. company to surpass a $1 trillion market capitalization, driven by strong performances in its insurance, energy, manufacturing, and retail sectors. This milestone comes as Berkshire's stock has rallied 30% in 2024, outperforming the S&P 500's 18% rise. Buffett's investment strategy, characterized by disciplined, value-based investing, has enabled Berkshire to achieve impressive returns, even outpacing Bitcoin's performance this year. Meanwhile, Nu Holdings, another Buffett-backed company, has been performing well, with its stock surging on strong earnings and revenue growth. Buffett's focus on fundamental value and long-term growth continues to be validated, as evidenced by his successful diversification and strategic investments.
