Coherent profit jumps 91% as AI data centre demand drives growth; shares rally

Coherent reported a 91% jump in profit, with the rally in its shares attributed to surging demand for optical components used in AI data centres. The transmission mechanism runs through the AI infrastructure capex cycle: hyperscaler and cloud spending on high-speed networking translates into orders for optical transceivers and lasers, pulling forward revenue and reinforcing investor conviction in the broader AI buildout. This strengthens the case that hardware suppliers across the networking and semiconductor supply chain are capturing a disproportionate share of AI-related spending, with optical and photonics names and data-centre-exposed equipment makers most directly sensitive to the same demand signal. Traders should watch the next hyperscaler capex guidance updates and Coherent's forward order commentary, since any signs of spending deceleration would test whether this earnings strength is durable or a single-cycle peak.

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.
