The Invesco QQQ Trust (QQQ) closed at $516.70 on January 15, 2025, up 2.3% as the Nasdaq 100 surged following the release of December's Consumer Price Index (CPI) data. The Nasdaq 100 index rose by 2.31% to 21,237.85, driven by investor optimism over the Federal Reserve's potential continuation of interest rate cuts. The CPI data showed a y/y increase of 2.9%, aligning with expectations, while the core CPI rose by 3.2%, slightly below forecasts. This eased concerns about inflationary pressures, leading to a decline in Treasury yields and boosting tech stocks.

Additionally, strong earnings reports from major banks further bolstered market sentiment.
