Market Report, 2026-09-18

U.S. stocks finished a volatile week with mixed results as investors absorbed the Federal Reserve’s first interest-rate increase since 2023, persistently high oil prices, and Treasury yields near psychologically important levels. The Dow Jones Industrial Average closed Friday at 51,683 and lost about 1.7% for the week. The S&P 500 finished at 7,651, down roughly 0.1% for the week, while the NASDAQ Composite ended at 26,523 and gained approximately 0.7%.

The week’s dominant story was the renewed pressure from interest rates. The Fed raised its benchmark rate by a quarter percentage point Wednesday and signaled that additional tightening remains possible as inflation stays elevated. Treasury yields reflected that concern: the 5-year yield ended near 4.87%, while the 10-year climbed to 5.00%. The average 30-year mortgage rate jumped to 6.95%. Higher yields weighed most heavily on the Dow and other rate-sensitive areas, although technology-related shares proved more resilient.

Sector performance was similarly uneven. Technology and communication-services shares benefited from continued enthusiasm around semiconductors and artificial intelligence, helping the NASDAQ outperform. Energy lagged Friday as crude prices retreated, although oil remained elevated enough to keep inflation concerns prominent in the broader market narrative.

Next week, investors will focus on preliminary September business-activity data, new-home sales, weekly jobless claims, and durable-goods orders. These reports could help determine whether markets become more comfortable with the Fed’s tighter policy stance or continue pushing Treasury yields higher.
