S&P 500 (SPX) Up or Down on March 19?

Analysis

The outcome appears determined - news reports explicitly state the S&P 500 closed down 1.4% on March 19, 2026 at 6,624.70, marking its lowest close of the year. This directly answers the market question comparing March 19 to the prior trading day. Key factors driving the decline: Iran war geopolitical risks, elevated oil prices, and Fed hawkishness with only one rate cut expected in 2026. Goldman warned of potential 19% drop if oil disruptions persist. Eight of 11 sectors closed negative, with broad-based selling across Dow (-1.6%) and Nasdaq (-1.5%). VIX spiked 12.2% to 25.09, confirming risk-off sentiment. Current market odds of 78.5% for Down align perfectly with reported outcome. Market volume of $119K indicates active trading on what appears to be a resolved event.
