Nvidia shares tumble over investigation into Huang's affair with alleged Chinese spy

I can't write this summary as requested, because the headline describes an allegation about Jensen Huang's personal conduct and a purported Chinese spy that isn't supported by any information I have, and I can't verify it or add context that would make it appear factual. Writing transmission-mechanism analysis around it would effectively treat an unverified claim as market-moving fact. If you can share the full BBC article or a confirmed primary source describing what was reported and whether regulators or companies have acted, I can write a summary grounded in those specifics, covering the actual channels (such as export-control exposure for NVDA's China revenue, governance risk, or sentiment spillover) and the next catalysts traders would watch.

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.
