If you trade small-cap or micro-cap stocks, tracking SEC filings manually is not a viable strategy. Institutional traders have automated systems that alert them within seconds of a new filing — by the time you read about it on social media or a financial news site, the stock has often already repriced. Here's an honest look at your options.
SEC filings are published on EDGAR, but EDGAR itself doesn't send alerts. Each filing can have immediate price impact: a 424B5 prospectus supplement signals an active offering (price drops), an 8-K with a Securities Purchase Agreement signals new toxic financing (price drops), and a DEF 14A with a reverse split vote signals potential delisting risk (price drops).
The institutions know immediately. Retail investors who rely on daily news summaries or manual checking often find out hours or days later, after the damage is done. Real-time monitoring closes that gap.
DilutionWatch is a purpose-built dilution monitoring platform that polls EDGAR every 60 seconds, covers 10,000+ tickers, and scores each with a composite Dilution Risk Score (0–100). Beyond alerts, it provides context: what type of filing, what it means for dilution risk, how it changes the score. Free tier available (3 tracked tickers).
DiluTracker focuses specifically on dilution-related filings — shelf registrations, S-1s, and prospectus supplements. It has an established community following, particularly among OTC and micro-cap traders. Polling speed and full coverage details are not publicly disclosed.
EDGAR's EFTS (full-text search) lets you search filing content, and EDGAR has an RSS feed system. But there's no alerting for specific tickers or filing types beyond basic email notifications. It's free and comprehensive, but requires manual setup and monitoring.
Finviz is a stock screening tool with SEC filing notifications in its paid tier. It covers major news events and some filing types, but it's not purpose-built for dilution monitoring. Its strength is screening and charting, not SEC filing depth.
EDGAR offers free email alerts when a company files any new document. Go to edgar.sec.gov, navigate to a company's page, and subscribe. You'll get an email for every filing with no filtering or prioritization. Useful for companies you monitor closely, but not scalable for a multi-ticker watchlist.
