How good is this stock, really? One app to research it, score it, and keep watching it - so you can decide whether to buy, hold, sell, or just keep tracking. - THE SENTEX SCORE Six factors, one score, recalculated nightly: valuation against sector peers, revenue and earnings trajectory, profitability, momentum, analyst expectations, and insider activity. The same weights, applied to every stock. Tap any factor to open the numbers behind it - the multiples, the estimates, the raw figures the score is built on. Everything you need to size up a stock in one view, instead of five tabs and a spreadsheet. YOUR THESIS, TRACKED Sentex generates multiple bull and bear cases for any stock, built from its own data and research. You pick the cases you actually believe in. Then let Sentex watch the news for you. Every article on the stock is checked against your exact thesis, and when one genuinely confirms it - or challenges it - you get a notification naming which point moved and why. Nothing when it is noise. If you invest over years rather than days, this is the part that gets hard alone: remembering what convinced you a year ago, and catching the moment it quietly stopped being true. Sentex keeps that record and does the reading, so months of coverage take seconds to review. You stay in control. Mark a point as still holding, or close it. What you do next is your call. WHAT THE SMART MONEY IS DOING Insider buying, filtered for conviction rather than noise. Congressional STOCK Act disclosures. Hedge fund 13F holdings. Cross-referenced against the score, so you can see when the people closest to a company disagree with the numbers. THE RIPPLE MAP No company moves alone. When something lands at one company, see the suppliers, customers and peers it connects to - flagged as under pressure, worth watching, or a possible beneficiary, with today's move on each. VALUATION IN CONTEXT Analyst consensus and price targets, peer multiples, upside to target, earnings and IPO calendars. Free, on any stock you search. STOCKS WORTH A SECOND LOOK Divergence finds stocks down sharply from a recent high whose fundamentals never actually deteriorated - and that have already started climbing back. Filter by Sentex Score to keep only the quality names. Alongside it, Insider Conviction surfaces stocks where multiple insiders are buying, or one has bought in size - the kind of buying that is hard to dismiss as routine. Free users see the top name on each list; Pro opens the rest. NEWS THAT MATTERS Every headline on your watchlist classified by sentiment and materiality, with the reasoning shown. Skip the noise, read the catalysts. - FREE 5 stocks on your watchlist, alerts, and full research on any stock you search. No trial, no card required. PLUS 10 stocks, unlimited alert rules, and market-wide alerts. PRO 25 stocks, the full Sentex Score library, the Top 10 ranked list, the complete Divergence and Insider Conviction screens, hedge fund holdings, Congressional and insider trades, and the full earnings, IPO and dividend calendar. - Start free. Research any stock, track it, set your thesis, and let Sentex do the reading and keep watch. Sentex is not a broker and does not give buy or sell advice. It does the reading, the maths and the cross-referencing so the decision stays yours.
