Nasdaq Sinks 5% in October as AI Stock Selloff Hits Tech

The Nasdaq fell roughly 5% over October as a selloff in artificial intelligence-linked stocks weighed heavily on large technology names. The move points to a risk-appetite and valuation-compression channel: investors reassessing the premium multiples assigned to AI beneficiaries, with a rotation out of high-growth equities pressuring the index's heavy weighting in mega-cap tech. The Nasdaq-100 (NDX) is most directly exposed given its concentration in the same mega-cap names driving the AI trade, while broader indices with lower tech weightings would show a smaller drawdown. Traders should watch the next Consumer Price Index release and Federal Reserve rate expectations, since any hotter-than-expected inflation print could further raise discount rates on long-duration growth stocks and extend the pressure on NDX.

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.
