   Dow Rises as S&P 500 and Nasdaq Slip Amid Iran Sanctions

   The Dow Jones Industrial Average rose while the S&P 500 and Nasdaq declined as markets reacted to a new U.S. global sanctions plan against Iran. Bessent announced an "economic asphyxiation" campaign against the nation, causing tech stocks to drag down broader indices. Investor focus remains split between these geopolitical tensions, upcoming Nvidia earnings, and the Jackson Hole symposium. While the Dow gained, semiconductor firms including Micron and Sandisk saw price drops. International markets also felt the impact, with Indian shares falling as investors sought more details on the sanctions.

   Why it matters

   The U.S. is implementing a global sanctions strategy to pressure Iran economically. This occurs alongside heightened volatility in the tech sector due to scrutiny over AI spending. Markets are currently pricing in risks from a U.S.-Canada trade war and pending inflation data.
