On September 22, the Nasdaq Composite reached a new intraday record, trading between 27,211 and 27,231 points. This follows a record closing of 27,122.09 on September 21, which was the index's first record close since early June.

The growth of the Nasdaq was driven by major technology and AI-related companies. Alphabet shares rose by approximately 2%, while AMD and Intel recorded double-digit percentage gains during the session.

In contrast, the Dow Jones Industrial Average fell by approximately 270 points, with losses fluctuating between 194 and 290 points. The decline was attributed to weakness in the financial and energy sectors.

Market conditions were influenced by the 10-year Treasury yield, which traded near 4.9%, and Brent crude oil prices, which moved toward $100 per barrel. These factors contributed to a shift in capital toward growth-oriented tech stocks.
