Market Unease Amid Iran-Israel Tensions Stalls S&P 500 and Nasdaq

The U.S. stock market ended the week on a cautious note, with the S&P 500 and Nasdaq both closing lower. This followed investor anxiety over escalating tensions between Iran and Israel, and possible U.S. involvement in the conflict. The Dow Jones, however, managed to eke out a slight gain.

Market volatility was fueled by Israel's ongoing military actions aimed at curbing Tehran's nuclear capabilities, as Iran asserted it would not negotiate under attack. President Donald Trump faces a critical decision regarding U.S. intervention, adding pressure to global markets.

The expiration of stock options and futures contracts further contributed to Friday's hesitant trading environment. Meanwhile, Fed officials' comments on tariffs and inflation risks, coupled with performance reports from major corporations like Kroger and Accenture, rounded out a week of economic uncertainty.
