Nvidia (NVDA) stock rose Monday after the chipmaker’s board authorized an additional $150 billion for share repurchases, the largest buyback increase on record. The move lifts Nvidia’s remaining authorization to $235 billion, which the company expects to use through fiscal 2028, a period that ends in late January 2028. It surpasses Apple’s $110 billion authorization from 2024. Shares gained roughly 2% to 3% in Monday trading even as the S&P 500, Nasdaq and Russell 2000 all traded lower.
