Despite a holiday-shortened week and light volume, U.S. stocks pulled back from recent highs last week as year-end positioning and lack of fresh catalysts weighed on sentiment. The S&P 500 and Nasdaq slipped after failing to sustain record levels, while tech and small caps bore the brunt of profit-taking amid mixed breadth. For the week, the S&P 500 fell about 1%, the Dow lost roughly 0.7%, the Nasdaq slid near 1.5%, and the Russell 2000 dropped by around 2.1%.
