U.S. stocks are falling as Wall Street heads toward a fifth straight week of losses, the longest such streak in nearly four years. The S&P 500 dropped 0.7% and deepened its losses a day after its worst drop since the conflict with Iran began. The Dow Jones Industrial Average fell 319 points, and the Nasdaq composite sank 1.1%. President Donald Trump's latest delay in his threat to attack Iranian power plants saw oil prices briefly pull back late Thursday, but they resumed rising Friday as fighting continued in the Middle East.

The ongoing volatility in the stock market and rise in oil prices reflect the broader economic uncertainty caused by the escalating tensions between the U.S. and Iran. Investors are concerned about the potential for further military conflict and its impact on the global economy.
