Why Google is making headlines in Berkshire's biggest quarter of stock-buying

In a remarkable shift, Berkshire Hathaway has expanded its investment in Alphabet, acquiring approximately 106 million shares, marking its most significant stock purchase quarter in years. Additionally, the conglomerate escalated its Delta Air Lines investment by 44 percent, with total stock spending exceeding $23 billion last quarter. This change ends a 14-quarter trend of being a net seller.
