Nasdaq Adds 400 Points After CoreWeave Earnings: Stock Market Today

The Nasdaq rose roughly 400 points following CoreWeave's earnings report, according to the headline, with the move attributed to the AI infrastructure provider's results. The transmission mechanism runs through risk appetite and sentiment toward AI-linked capital spending, as stronger results from a company tied to GPU cloud demand tend to reinforce expectations that hyperscaler and data center investment will continue. The Nasdaq-100 (NDX) is the most directly exposed index given its heavy weighting toward mega-cap technology and semiconductor names that supply or benefit from AI compute buildouts. Traders will watch whether the rally broadens beyond AI-adjacent names or remains concentrated, and whether upcoming Nvidia and other semiconductor earnings confirm the demand signal that CoreWeave's report implied.

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.
