Warren Buffett’s Berkshire Hathaway reached a $1 trillion market capitalization, becoming the first non-technology company in the U.S. to achieve this milestone. The company's shares surged by 28% in 2024, outperforming the S&P 500's 18% gain. This milestone was reached just days before Buffett's 94th birthday. Berkshire is known for focusing on traditional industries like railroads and insurance, although its significant Apple investment contributed to recent gains. Buffett's recent moves have prompted some Wall Street followers to believe he may have concerns about the economy and market valuation.
