The Invesco QQQ Trust (QQQ) closed on January 21st at $524.80, up 0.59%, as the Nasdaq-100 index it tracks rose by 0.58% to 21,566.51, driven by optimism in the technology sector. The positive movement in the index was largely influenced by a favorable reaction to last week's light CPI report, which led to a drop in bond yields and a subsequent rally in tech stocks. This inverse correlation between equity returns and bond yields has been a key driver for the index, as highlighted by Morgan Stanley's recent analysis. Additionally, the ongoing advancements in artificial intelligence continue to bolster investor sentiment, with major tech companies like Meta Platforms and Microsoft making significant strides in AI technologies. These developments are seen as catalysts for future growth, contributing to the bullish outlook for tech-heavy indices.
