Sea (Shopee) shares plunge 19% in 4 days to multi year low after announcing AI business — I hold this stock. Will I sell, or buy more?

Sea Limited, the parent of e-commerce platform Shopee, saw its shares fall 19% over four days to a multi-year low following its announcement of an AI business initiative. The reaction reflects a transmission channel through investor risk appetite and growth-multiple repricing, as the market appears to be discounting the AI move against the company's existing profitability and capital allocation outlook, rather than reacting to a change in macro conditions. Exposure is concentrated in Sea's own equity and in other Southeast Asian internet and e-commerce names, which tend to trade together on regional growth sentiment and foreign capital flows. Traders should watch the company's next quarterly earnings release for disclosure on AI spending, margins, and Shopee's core marketplace growth, since management commentary on capital allocation will determine whether the selloff reflects a durable reassessment or an overreaction.

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.
