Stock Market Today: Dow Falls On Trump's Iran Threat, Peace Talks; Netflix Rallies On Upgrade (Live Coverage)

U.S. stock markets opened lower Monday as geopolitical tensions escalated after President Trump issued new threats against Iran, overshadowing ongoing but stalled Middle East peace negotiations. The Dow Jones Industrial Average led declines, dropping over 1% in early trading, with defense and energy sectors underperforming amid fears of regional instability disrupting global oil supplies. Netflix shares surged 4% following an analyst upgrade, bucking the broader market trend, as investors bet on stronger-than-expected subscriber growth in its upcoming earnings report. Tech-heavy Nasdaq showed relative resilience, dipping just 0.3% as mega-cap growth stocks like Microsoft and Nvidia offset broader sell-offs in cyclical sectors tied to geopolitical risks. Traders cited Iran’s potential retaliation and uncertainty over U.S. military posture as key drivers, while bond yields fell as investors sought safe-haven assets like Treasuries.
