On December 26, Wall Street opened lower as rising U.S. Treasury yields pressured investor sentiment, leading to a slight decline in major indexes. The Dow Jones Industrial Average and other key indexes faced challenges due to the increase in long-term interest rates, which reached new highs. As trading progressed, the market stabilized, closing largely flat amid low trading volumes following the holiday period. The dollar also experienced fluctuations, closing slightly above $990, influenced by a drop in copper prices and anticipation of upcoming macroeconomic data from the U.S. On December 27, the Nasdaq Composite fell by 2%, contributing to a negative start for Wall Street, although the main indexes were still on track for a positive week overall despite the cautious sentiment among investors.
