US Stock Market Live Updates: Nasdaq futures slip as Qualcomm tumbles 10%; Dow, S&P 500 gain

Nasdaq futures slipped while Qualcomm shares fell roughly 10%, even as the Dow and S&P 500 advanced, according to the Economic Times live coverage. The divergence points to a sector-specific reaction rather than a broad risk-off move, with the drop in a single semiconductor name weighing on the technology-heavy Nasdaq 100 while cyclical and value-oriented components supported the Dow and S&P 500. Qualcomm, as a large-cap chipmaker with significant exposure to smartphone and automotive semiconductor demand, is the most directly exposed asset, and its decline pressures NDX through index weighting given the company's size within the benchmark. Traders should watch whether the weakness spreads to other semiconductor and mega-cap technology names, which would signal a shift in sector sentiment, and the next move in Nasdaq 100 futures relative to the broader indices as an indicator of whether rotation or stock-specific repricing is driving the session.

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.
