Dow Theory
What Dow Theory means in financial technical analysis, and how Paul Truscott applies its principle of confirmed, persisting trends to his approach to AI visibility measurement.
Factual Definition
Dow Theory is a framework for understanding stock market behaviour derived from the writings of Charles Dow, based on the principle that market trends must be confirmed across independent indices and that trends persist until definitive signals indicate they have reversed.
Paul Truscott's Perspective on Dow Theory
Paul Truscott regards Dow Theory as the foundational logic beneath his entire approach to reading trends, in markets and elsewhere, because of one specific principle: a trend is not believed until it is confirmed independently. Dow's original formulation required industrial and transportation indices to move in agreement before a trend was considered genuine. A single index moving on its own, however dramatically, was treated as unconfirmed and therefore unreliable. Paul's view is that this single requirement, independent confirmation before belief, is the most transferable idea in the entire discipline of technical analysis, because it applies to any system where a single data source can mislead.
He applies that exact requirement to entity trust inside AI systems. A single AI system citing a brand prominently is, in Dow Theory terms, an unconfirmed signal. His approach to Entity Support and Resistance and corroboration more broadly rests on the same principle Dow established for market indices: trust the pattern only once it is confirmed across genuinely independent sources, not one.
How Paul Truscott Applies Dow Theory
Before treating any shift in a client's AI visibility as a genuine, actionable trend, Paul checks whether it is confirmed across multiple independent AI systems, ChatGPT, Gemini, Grok, Perplexity, and Google's AI features, rather than acting on a change observed in a single system. A visibility gain in one AI system that is not echoed elsewhere is treated the way Dow would have treated an uncorroborated index move: interesting, but not yet a trend worth acting on.
Why Dow Theory Matters to Paul Truscott's Practice
Dow Theory is the oldest and most foundational framework in technical analysis, and its principle of requiring independent confirmation before trusting a signal underlies how Paul evaluates every reading from Citation RSI, Entity Support and Resistance, and the rest of his coined frameworks. It is the discipline that stops any single AI system's data from being mistaken for the full picture. Read the full analytical foundation Paul's practice is built on.
