Intro to Scanners
Scanners turn the whole market into a shortlist. Instead of manually going through thousands of stocks, you pick a filter, and InvestorStack shows you which companies currently match it.
How to find and open scanners
It is simple to get to. On investorstack.in, log in, open the app, and look at the sidebar on the left. Click Scanners.
You will land on the scanners page. It shows every scanner we have as a card, split into two groups: Technical on top, Fundamental below. Each card has the scanner name and a one-line plain-English description of what it does. Click any card and you go into that scanner, where you see the stocks currently matching it.
That page is the map of everything this manual part covers. Every card links to its own explainer page.
Two families of scanners
InvestorStack has 19 scanners in two families: 16 technical and 3 fundamental. (We will be adding more in coming days.)
Technical scanners read price action. They answer "what is the market doing with this stock?" Breakouts, relative strength, moving averages, momentum, and the stage of the trend all live here.
Fundamental scanners read the company itself. They answer "what is this company growing into?" Guidance from earnings calls, which conference calls are worth reading this season, and where a business sits on the path to an earnings acceleration all live here. These are proprietary scanners using rich investorstack's company data.
Technical scans tell you when to act. Fundamental scans tell you what is worth acting on. Together they make a complete workflow.

Alerts
Every scanner has a bell. Turn it on and InvestorStack sends you a Telegram alert when new signals fire for that scan. You learn about a breakout or a new stage transition the moment it happens, without checking.
Top Gainers catalysts
Open Top Gainers in India or US and choose Catalyst. The table updates once after each market closes. Each row shows that session's one-day return, news sentiment, and a short explanation with source links. If the available news does not support a cause, the row says so.
Where to go next
If you are new, start with relative strength, because it is the building block behind many of the other scans. Then the stage framework, because it is the backbone of the trend scanners. Then pick one scanner you care about and read its chapter.
