According to @StockMKTNewz, Berkshire Hathaway’s top holdings in Q2 2015 were Wells Fargo (WFC) 24.1%, Coca-Cola (KO) 14.3%, and IBM 11.8%, highlighting a bank and consumer-staples tilt at that time, source: @StockMKTNewz. By Q2 2025, the top three shifted to Apple (AAPL) 22.3%, American Express (AXP) 18.8%, and Bank of America (BAC) 11.1%, concentrating exposure in mega-cap tech and financials, source: @StockMKTNewz. This reweighting makes Berkshire’s public-equity performance more sensitive to AAPL, AXP, and BAC price action than a decade ago, a concentration dynamic derived from the stated position sizes, source: @StockMKTNewz.
