89% of Warren Buffett's Portfolio Is Invested in These 12 Stocks
Warren Buffett has overseen some truly jaw-dropping investment gains since becoming CEO of Berkshire Hathaway (NYSE: BRK.A)(NYSE: BRK.B) more than 57 years ago. Berkshire's Class A shares (BRK.A) have gained more than 3,600,000% since the beginning of 1965 (through Dec. 31, 2021). This is a 120 times greater total return than the broad-based S&P 500, including dividends paid, over the same time frame.
While Buffett's well-documented willingness to hold his investments for many years, if not decades, is a big reason for his success, an oft-overlooked factor that's been responsible for the Oracle of Omaha's outperformance is portfolio concentration. In Buffett's view, diversification is only necessary if you don't know what you're doing.
