Warren Buffett's Berkshire Hathaway reported another stellar quarter on Saturday, and the conglomerate revealed that three-quarters of its stock portfolio was tied up in just five names. The Omaha-based conglomerate said approximately 75% of the aggregate fair value was concentrated in five companies at the end of the third quarter. Buffett's juggernaut posted a big investment loss of $24.1 billion in the third quarter, largely due to a decline in its gigantic Apple stake.
The other four top holdings remained unchanged last quarter: $22.4 billion worth of American Express , $34.2 billion of Bank of America , $25.4 billion of Coca-Cola as well as $30 billion of Chevron . The Chevron stake went up in value as the energy stock gained more than 7% during the quarter amid a jump in oil prices. Still, the "Oracle of Omaha" advised shareholders to ignore the quarterly fluctuations in Berkshire's equity portfolio.
