ESG Factor Momentum
Long names whose ESG scores are improving and short those whose scores are deteriorating — the change, not the level.
Definition
ESG Factor Momentum refers to the change, not the level. 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 the change, not the level 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 esg factor momentum is saying. If the change, not the level 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 ESG Factor Momentum: what would falsify the current reading in the next window?
