Central Limit Theorem
The central limit theorem says that sums of many independent, finite-variance shocks look Gaussian — which is why so many models start with a normal, and why they fail when those assumptions fail.
Definition
Central Limit Theorem refers to variance shocks look Gaussian — which is why so many models start with a normal, and why they fail when those assumptions fail. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It is a named object desks use to frame risk, positioning, or process. When variance shocks look Gaussian — which is why so many models start with a normal, and why they fail when those assumptions fail shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what central limit theorem is saying. If variance shocks look Gaussian — which is why so many models start with a normal, and why they fail when those assumptions fail moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Keep the definition fixed, then challenge it with cross-checks before sizing. Prefer a short written null hypothesis for Central Limit Theorem: what would falsify the current reading in the next window?
