Pre-Market Gap Scanner

SEC-Powered Gap Detection Before the Bell

What is a pre-market gap scanner?

A pre-market gap scanner identifies stocks likely to open significantly higher or lower than yesterday's close. Traditional scanners use price-based screens (volume spikes, pre-market movers). Catalyst Edge takes a different approach: scanning SEC EDGAR filings overnight to find the catalysts that cause gaps before they show up on price screens.

How the Catalyst Edge scanner works

Every morning, the scanner: (1) Pulls 300+ new SEC filings from EDGAR, (2) Classifies each by catalyst type (8-K event, insider buy, activist filing), (3) Scores tickers using a multi-factor model (filing type, historical gap rate, sector momentum, insider activity), (4) Publishes a ranked watchlist before 8 AM ET with the top picks for the day.

Scanner categories

Gappers: High-probability gap-up candidates based on material filings + price momentum. Value Plays: Undervalued tickers with positive filing catalysts (insider buying at lows). Moat Builders: Companies with structural advantages (patent filings, recurring revenue, debt reduction) showing through their SEC filings.

Why SEC filings beat price scanners

Price scanners show you what already happened. Filing scanners show you why it's about to happen. By the time a stock shows up on a pre-market mover list, the gap is already priced in. Catalyst Edge finds the filing first, letting you position before the gap appears on price screens.
