investingLive Americas FX news wrap 5 Nov: Nasdaq 100 plunges 6.36% as AI selloff spreads

The Nasdaq 100 fell 6.36% in the session covered by the investingLive Americas FX wrap for 5 November, with the decline attributed to an AI-related selloff that spread across the index. The move reflects a repricing of expectations for the earnings and capital spending trajectory of large-cap technology companies, which carry outsized weight in the NDX and have been the primary beneficiaries of AI-driven valuation expansion. Because the index is concentrated in a small group of mega-cap names, a sector-wide reassessment transmits directly into index-level losses and can spill into broader risk appetite, with high-multiple growth equities and AI-exposed semiconductor and cloud names most exposed. Traders will be watching whether selling pressure persists in the next session and whether hyperscaler capital expenditure guidance or upcoming Nvidia-linked supply chain commentary signals a durable change in AI investment demand.

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.
