Wall Street Opens Lower Amid Iran Tensions and Economic Data Looms

US stock markets opened lower on Monday as investors grappled with the implications of the US pledge to take an 'economic D-Day' stance against Iran. The Dow Jones Industrial Average fell 15.1 points, or 0.03%, to 53,261.95 at the opening bell.

The S&P 500 and Nasdaq Composite also declined, with the S&P 500 down 11.0 points, or 0.14%, to 7,663.38, and the Nasdaq Composite dropping 115.1 points, or 0.44%, to 26,065.32.

Investors are awaiting key data releases later this week, including Nvidia's quarterly earnings report and a closely watched inflation report. The market is particularly sensitive to these events due to their potential impact on interest rates and economic growth.
