Stop guessing which headlines matter. 42 Port scores every US stock news event for its Impact and Duration, and every stock for its Signal, so you get the bottom line in seconds. Scrolling through endless market news trying to figure out what actually moves a stock? That's exactly why we built 42 Port. Our AI reads the news for you and turns it into clear numbers you can act on, across roughly 8,000 US stocks on the NYSE and Nasdaq. EVERY EVENT, SCORED • Impact (-10 to +10): how strongly a news event is likely to move the stock's price. A +9? Something seriously bullish just happened. A -8? Watch out. A +2? Probably noise, so skip it. • Duration (Today · Days · Weeks): a quick blip or a lasting shift? Know how long an event may keep shaping the stock's direction. • 42 Event: every story is classified by type, like Major Contract, Executive Change, Regulatory Approval or Forecast Update, so you know what kind of news it is at a glance. • AI summary: the key facts of each story in a few lines, with a link to the original source. EVERY STOCK, SIGNALED • 42 Signal: one plain-language label that combines a stock's scores into a single takeaway, from Extreme Positive to Extreme Negative. • News Sentiment: the overall tone of a stock's recent news, from -10 to +10. • Latest Impulse: how much the newest event breaks from what the market has already been seeing. • Stock chart: recent events plotted by Impact, fading over time based on their Duration, so you see what's been driving the stock. • Market Sentiment: a real-time read on the whole market, combining live price moves with the Fear Index. BUILT AROUND YOUR STOCKS • Market feed: a live stream of US stock events, ranked by importance and updated throughout the trading day. • Watchlist feed: news for only the stocks you follow. Temporarily hide tickers to focus on a subset. • Stock pages: price, scores, chart and an event feed for any ticker. • Fast search: find any US stock by name, ticker or keyword. Search "Musk" to find Tesla, or "iPhone" to find Apple. • Filters: narrow any feed by Impact score or by Signal. • Bookmarks and sharing: save events for later, or share them with a friend. ALERTS THAT MATTER • Stock notifications: tap the bell on any stock to get notified when significant events are scored. • Extreme Market Alerts: know the moment Market Sentiment hits Extreme Positive or Extreme Negative. • Extreme Stock Alerts: know the moment a stock's 42 Signal hits an extreme. • Breaking Impact Notifications: catch sharp Impact shifts as they happen, sometimes on stocks you weren't even watching. 42 PORT PREMIUM 42 Port is free to try.
