Conviction Band

How it is measured

A band sits on top of a composite score, and that score combines several independent subsignals rather than relying on one. The point of combining is that agreement across different kinds of evidence is more informative than a single strong reading.

Because the inputs disagree as often as they agree, the composite is shrunk toward neutral when the signals conflict. Conviction rises with genuine cross-signal agreement, not with the loudest individual input.

How to read it

A high band means several independent measures point the same way at once. A low band does not mean the idea is wrong, it means the evidence is currently mixed and the position should be sized accordingly.

Bands are more useful for sizing than for direction. The question a band answers is how much to commit, not whether to be in or out.

A worked example

Two ideas can both look attractive on momentum alone. One also has supportive policy, improving flows and a favourable cycle fit. The other has momentum and nothing else. Both might rise, but only one has multiple independent reasons to, and that difference is what the band is trying to express.

The most common mistake

Reading a band as a prediction of return. It is a statement about the current weight of evidence, and evidence changes. A band that falls has not necessarily been proven wrong; the case has weakened, which is different.

How CORVIX uses it

Each of CORVIX's 17 secular themes gets a conviction band together with a plain-English condition that would prove the idea wrong. The falsification condition matters more than the score: an idea you cannot describe a way of being wrong about is not an idea, it is a belief. Themes are reviewed on a fixed schedule so a stale thesis cannot quietly persist.

Common questions

What is Conviction Band?

A conviction band is a label that summarises how strong the evidence behind an investment idea currently is. Rather than publishing a bare number, the score is placed into a named band so that the strength of the case is legible at a glance.
