Warren Buffett's Berkshire Hathaway has sold approximately 150 million shares of Bank of America (BofA), totaling nearly $5.4 billion since mid-July, raising alarms among Wall Street investors about potential economic challenges. Despite being BofA's largest shareholder with an 11.1% stake, Buffett's decision to divest nearly 15% of his holdings in a short period has led analysts to speculate about forthcoming market turmoil. Brian Moynihan, BofA's CEO, has attempted to attract investors through dividends and share buybacks, but Buffett's actions suggest he may have concerns regarding the economy. Some analysts believe Buffett's sales could simply be profit-taking, as BofA's stock has risen significantly over the past year. Historically, Buffett's investments have reflected confidence, particularly after he started buying BofA stock in 2011 following the financial crisis. Regulatory requirements will force Berkshire to continue reporting sales until its stake dips below 10%.
