The Invesco QQQ Trust (QQQ) closed at $513.08 on January 16, 2025, down 0.7% as the Nasdaq-100 Index faced pressure from significant declines in major tech stocks. Apple led the downturn with a 3.7% drop, marking its worst day since August 5, while Tesla fell 3.7% and Nvidia slid nearly 2%. The tech sector's struggles were compounded by comments from Treasury Secretary nominee Scott Bessent, who warned of economic risks if the 2017 tax cuts are not renewed, and Federal Reserve Governor Christopher Waller, who hinted at potential rate cuts contingent on inflation data. These factors contributed to a volatile trading environment, with the Nasdaq-100 Index declining by 0.69% to 21,091.25.
