U.S. stock-index futures were little changed Sunday evening after Wall Street recorded weekly losses as government-bond yields fluctuated and uncertainty persisted over efforts to resolve the Middle East conflict. At 20:19 ET (00:19 GMT), S&P 500 Futures were unchanged at 7,692.50 points, Nasdaq 100 Futures were muted at 29,390.50 points and Dow Jones Futures were flat at 53,346.0 points. The S&P 500 fell 1.43% last week, the Nasdaq dropped 2.1% and the Dow declined 0.9%, ending a three-week winning streak for the S&P 500 and Nasdaq. A rise in long-term Treasury yields pressured growth and technology shares, with the 30-year yield reaching its highest level since 2007 and the 10-year yield hovering around 4.7%. Treasury Secretary Scott Bessent doubled planned purchases of longer-dated government debt, but the relief was temporary. Middle East tensions also kept investors cautious after President Donald Trump threatened sanctions against countries trading with Iran. Brent crude remained above $93 per barrel after rising more than 6% the previous week. Investors are now focused on NVIDIA Corporation's quarterly results on Wednesday, the Federal Reserve's Jackson Hole symposium from Aug. 27-29, where Fed Chair Kevin Warsh is scheduled to speak, and July personal consumption expenditures inflation data.
