Stock Market Today, Aug. 17: Markets Inch Lower and Treasury Yields Rise as Investors Wait for Retail Earnings

Major stock indices fell slightly on August 17, 2026, with the S&P 500 down 0.50%, Nasdaq down 0.31%, and the Dow down 0.51% as investors adopted a cautious stance ahead of key retail earnings reports from companies like Walmart, Home Depot, and Target. Treasury yields rose, with the 10-year yield climbing to 4.68% and the 30-year hitting 5.3%, its highest level since 2007. The market's modest decline reflects a 'risk-off' approach as investors await retail corporate earnings.
