Stock market today: Dow, S&P 500, Nasdaq rise after Trump extends US-Iran ceasefire

U.S. equities advanced as the Dow, S&P 500, and Nasdaq rallied following former President Trump’s announcement extending a U.S.-Iran ceasefire, easing immediate geopolitical tensions in the Middle East. The market response reflects improved risk appetite, with investors repricing the likelihood of supply disruptions and military escalation that could impact energy markets and global trade flows. This de-escalation supports cyclical and growth-sensitive sectors, particularly technology (NDX) and industrials, while reducing demand for safe-haven assets. The extension of the ceasefire may also temper near-term oil price volatility, indirectly supporting equity valuations sensitive to input costs. Traders will watch the next U.S. CPI release for signals on whether reduced geopolitical risk allows the Fed to maintain a dovish stance amid inflation trends.

The Nasdaq-100 (NDX) is the US large-cap tech benchmark. NDX is more sensitive to rate decisions than SPX because of longer-duration cash flows, and heavily concentrated in Tech/Comms names — mega-cap earnings season dominates price action.

HIGH-impact news is typically a market-moving event with multi-pip or multi-percent intraday reactions. Examples include central bank rate decisions, major CPI/NFP releases, geopolitical shocks, mega-cap earnings beats/misses, and regulatory announcements. Traders typically position-reduce or hedge ahead of scheduled HIGH-impact events, and follow the wire in real time to react to unscheduled ones (war headlines, central-bank emergency statements, surprise corporate actions). The Trading News Terminal squawk box reads every HIGH-impact headline aloud the moment it hits the wire — so active traders don't have to stare at the feed.

Active traders typically follow a three-step workflow when a market-moving headline hits the wire: (1) read the headline on the terminal or hear it on the squawk box; (2) assess whether the news is already priced in (by checking intraday price action in the seconds before) or whether it's genuinely new information; (3) act — either entering a breakout position, fading an overreaction, or tightening stops on existing trades. Trading News Terminal's Pro plan delivers wire-grade headlines within seconds of the source, with automatic audio squawk on every HIGH-impact event, so the read-assess-act cycle never waits on a refresh button.
