Announcement Effect
Announcement Effect — Immediate market reaction to scheduled releases.
Definition
Announcement Effect refers to immediate market reaction to scheduled releases. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It frames the cyclical backdrop that equity, credit, and rates desks price into risk budgets. When immediate market reaction to scheduled releases 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 announcement effect is saying. If immediate market reaction to scheduled releases 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
Read with revisions, survey soft data, and market-implied paths — prints without the revision cycle mislead. Prefer a short written null hypothesis for Announcement Effect: what would falsify the current reading in the next window?
