Megatrend

How it is measured

A structural theme cannot be validated the way a short-term trade can, because the horizon is longer than any meaningful sample of price data. What can be tested is whether the conditions the thesis depends on are still present.

That makes the discipline different. Instead of asking whether the theme is working, the useful question is whether the reason for holding it still holds, and whether anything that would falsify it has occurred.

How to read it

A megatrend performing badly over one year tells you very little. A megatrend whose underlying premise has been contradicted tells you a great deal, and those are different observations that are easy to confuse.

The main practical risk is not being wrong. It is holding a theme long after the reason for it has quietly expired, because nobody scheduled a review.

A worked example

A theme premised on a sustained capital expenditure cycle in a particular industry is not falsified by a weak quarter. It is falsified by capital expenditure plans being cut. One is noise against a multi-year horizon; the other is the thesis breaking.

The most common mistake

Letting a long horizon become an excuse. Because a structural theme cannot be judged over short periods, it is easy to treat every drawdown as patience rather than evidence. That is precisely why a written falsification condition, set in advance, is the safeguard.

How CORVIX uses it

CORVIX tracks 17 secular megatrends and scores each one with a conviction band and an explicit falsification condition, reviewed on a fixed schedule rather than when someone remembers. The review cadence exists so that a thesis nobody has questioned in a year gets questioned.

Common questions

What is Megatrend?

A megatrend is a structural shift expected to play out over many years, independent of the business cycle. Unlike a tactical position, the case rests on something changing in the real economy rather than on price behaviour.
