Step One: D/load all EDGAR (US SEC) and SEDAR (Canada, TSX) and other exchange filings (each has thousands daily), and spend time learnng the various types (notifications, stock assignments, annual + quarterly reports, technical reports, board changes, etc) and patterns of key information.
Step Two: Magic AI + databases
Step Three: Profit! (or, at the very least a much deeper understanding of energy, resources, and trade flows and activities across the globe).
is a better example of that work from 15+ years back in just the resource sector (minus the AI woo, just with the factoid extraction and additional cross linking to global mineral lease).
