During the shortened Christmas week, the S&P 500, as tracked by the Vanguard S&P 500 ETF (NYSE: VOO), hit new all-time highs. It is now on track for its third consecutive year of double-digit gains and sixth in the last seven years. Technology stocks, particularly Nvidia Corp. (NASDAQ: NVDA), experienced significant growth, with Nvidia having its best week since late October. This surge was fueled by new deals related to next-generation artificial-intelligence chips. One such agreement was with AI chip startup Groq, reportedly valued at $20 billion for its inference technology. This move is expected to strengthen Nvidia's competitive position. Micron Technology Inc. (NASDAQ: MU) also saw a rise in its stock following a strong quarterly earnings report. It marked the stock's fifth straight weekly gain and tenth in the last eleven weeks.
