Warren Buffett's Berkshire Hathaway has significantly reduced its Apple stake, with holdings dropping from $174.3 billion at the start of the year to $69.9 billion by the end of September, marking a 60% decline. This reduction is part of a strategy where Berkshire has sold more stocks than it has bought over the past eight quarters, including Bank of America shares, while amassing a record cash reserve of $325 billion. Buffett has cited tax considerations for the Apple sales, and analysts suggest the decision aligns with concerns over high valuations and portfolio concentration management. Despite the sell-off, Apple remains Berkshire's largest investment, and the company maintains a cautious approach amid potential market turbulence. The move has sparked speculation about future acquisitions or strategic responses to economic uncertainty, signaling prudence amid high market valuations and geopolitical risks.
