The iShares Core S&P 500 ETF (IVV) closed at $610.89 on January 24, down 0.3% as the S&P 500 index faced pressure from mixed economic data and corporate updates. The S&P 500, which tracks the ETF, saw a decline of 0.29% to 6,101.24, influenced by a surprising drop in the Services PMI to 52.8, below expectations, and a revised consumer sentiment index falling to 71.1. These indicators contributed to a cautious market sentiment, despite a rise in Manufacturing PMI to 50.1, signaling expansion. The technology sector, a significant component of the index, was notably impacted, with Texas Instruments dropping 7.5% following disappointing guidance, and Nvidia falling 3.1%. Additionally, geopolitical tensions, including the US review of trade agreements with China, added to market uncertainty, leading to a rally in Treasury bonds and a weaker dollar.
