Signal Source Architecture

3 min read

Each trigger category has an optimal set of signal sources — the channels where that type of event first becomes detectable. Leadership changes appear on LinkedIn and press releases 24-48 hours before they appear in industry publications. Financial events appear in SEC filings and earnings calls hours before analyst coverage. Technology transitions appear in job postings and conference presentations weeks before public announcements. Regulatory shifts appear in government registers and industry association communications months before they affect operations. Mapping the optimal signal source for each trigger category determines which channels to monitor and at what frequency.
