Nasdaq Hits Record High Amid U.S.-Iran Diplomacy Uncertainty

The Nasdaq Composite closed at a record high on Tuesday, extending its winning streak to four sessions as traders navigated uncertainty surrounding U.S.-Iran diplomatic talks and their potential impact on oil prices. While the Nasdaq gained 0.5%, both the Dow Jones Industrial Average and S&P 500 ended in negative territory for the day. The meeting between American and Iranian representatives at the United Nations General Assembly, described by President Donald Trump as a 'very good meeting,' contributed to market volatility. Oil prices fluctuated amid geopolitical tensions; November Brent crude rose slightly while West Texas Intermediate fell. Treasury Secretary Scott Bessent indicated that the administration is considering whether to ban U.S. diesel exports, which led European gasoil futures to surge over 4%. The dollar also reached a near two-month peak against major currencies due to expectations of continued hawkish Federal Reserve policy. European equities declined on Wednesday as Brent crude prices climbed again, while Asian markets showed mixed performance with South Korea's Kospi rising and China’s CSI 300 falling. Investors are now turning attention toward upcoming earnings reports from General Mills, Paychex, and H.B. Fuller.
