Dow Dives as Iran Conflict Escalates. Stock Futures Slump.

Stocks futures were plummeting and oil was racking up further gains on Tuesday as investors fretted that the conflict in the Middle East would drag on. S&P 500 futures were 1.8% lower, and contracts tied to the tech-heavy Nasdaq 100 tumbled 2.2%. The moves lower came after Israel struck targets in Iran and Lebanon and Iran hit the U.S. Embassy in Saudi Arabia’s capital and other targets in Gulf states.
