Every row is a public regulatory disclosure — a Form 4 filing with the SEC — collected within minutes of being published. We don’t take company submissions and we don’t edit the numbers; the only thing we add is the rating and the reasoning behind it.
Sometimes. A insider buying with their own money is one of the few honest signals in the market, but plenty of purchases are routine — small top-ups, scheme allocations, or a well-paid executive rounding out a holding. That’s what our six-point check is for: it separates the conviction buys from the housekeeping, and shows you which is which.
The pipeline runs every 15 minutes through the trading day, so a new disclosure appears here shortly after it’s filed. Company stats refresh daily.
Yes — that’s what the app is for. Follow WESCO INTERNATIONAL INC and you’ll get a push the moment a insider files, with the full analysis attached, plus alerts if the price moves after a buy you’re following.
No. ddbx rates the conviction behind insider buys and shows the reasoning. It’s information, never a recommendation, and never a guarantee. What you do with it is your call.
