US Stock Futures Weaken Across the Board, Middle East Conflict Becomes Biggest Variable, Investors Await PMI Guidance

TradingKey - U.S. stock index futures edged lower on Tuesday as investors cautiously assessed ongoing attacks in the Middle East.

As of 8:20 a.m. ET, Dow Jones futures fell 137 points, or 0.29%; S&P 500 futures dropped 68 points, or 0.28%; and Nasdaq 100 futures declined 19 points, or 0.29%.

In terms of individual stocks, Micron Technology ( MU) fell more than 4% in pre-market trading; Palantir ( PLTR) rose over 6%; Tesla ( TSLA) shares edged higher in U.S. pre-market trading after the electric vehicle manufacturer achieved its first growth in monthly sales in Europe in more than a year.

On March 24 local time, Israeli officials stated that the likelihood of the U.S. and Iran reaching an agreement is "minimal." The rift stems not only from U.S. demands—including limits on Iran's nuclear program, ballistic missiles, and freedom of navigation in the Strait of Hormuz—but also from Iran's own requirements.

Two sources involved in the mediation said, "Currently, Iran is insisting that the U.S. provide compensation and guarantee that no further action will be taken against Iran under any agreement."

Beyond geopolitics, economic data is set to become the market's next focus, with the preliminary U.S. Purchasing Managers' Index (PMI) for March about to be released.

Analysts generally believe this data will provide a vital window into the state of the economy; if the PMI shows a significant slowdown in economic activity, it could exacerbate recession concerns and potentially impact the Federal Reserve's monetary policy path.

Market expectations for a Fed rate cut this year have significantly diminished, and investors are closely tracking economic data to capture clues regarding the direction of monetary policy.
