Two distinct approaches
These are not two halves of the same tool. They are two independent approaches that answer different questions and inform different decisions: the long-term thesis for one, the timing of entry for the other.
The economic analyst
An economic analyst builds a structural vision — demographics, debt, geopolitics, institutional confidence, productive structure. This vision guides a thesis over the long or very long term. A monthly or quarterly economic release — inflation, employment, trade balance — can validate or invalidate this thesis. It does not, however, give an entry signal: by the time a retail investor discovers a public release, the price has already moved. This is what Eugene Fama formalised in 1970 as the informational efficiency of markets (in its semi-strong form), a debated theory presented on the “Technical analysis pitfalls” page.
The technical analyst
A technical analyst formulates no thesis about the deep forces of an economy. They calculate. On a sufficiently large and rigorous sample, they measure what a rule written in advance would have returned, net of costs: how to spot the situation, where to exit if wrong, where to exit if right. That result, once put through the five tests presented on the “Technical analysis pitfalls” page, is what guides the decision. Economics plays no part in this reasoning. The edge is statistical, but it does not stand on its own: leverage and position size can ruin an account even when the strategy is good.
What distinguishes them
Neither is rigorous by nature: each becomes so through its method, and each has its limits, described on the “Technical analysis pitfalls” and “Economic analysis pitfalls” pages. What distinguishes them is the nature of the question they ask — and the time horizon on which they operate, as illustrated by the timeline below.
