Earnings Revision Cycle
The multi-quarter pattern of analyst earnings estimate changes — the cleanest forward signal of corporate fundamentals.
Definition
Earnings revision breadth (the ratio of upward to downward analyst revisions) leads realized earnings by 1–2 quarters and equity prices by 4–8 weeks. Persistent downward revisions ahead of stable equity prices signal vulnerability; the inverse signals coming upside.
Citigroup's Earnings Revision Index and Bloomberg's analogue are the standard benchmarks.
