Stock Market Today: Dow, S&P 500 and Nasdaq close at record highs on hopes for Iran war ending; oil prices drop; Micron extends epic run - MarketWatch

The Dow, S&P 500 and Nasdaq closed at record highs Wednesday as reports that the Iran war may be nearing an end eased geopolitical risk and sent oil prices lower.
