# Earnings Revision & Guidance Analysis
## Overview
Track sell-side analyst estimate revisions, management guidance changes, and post-earnings price drift to generate investment signals. Earnings revisions are among the most persistent and well-documented alpha factors in equity markets — stocks with upward revisions tend to continue outperforming, and vice versa.
## Core Concepts
### 1. Earnings Revision Momentum
**The revision signal hierarchy (strongest to weakest):**
| Signal Type | Description | Typical Alpha (annualized) | Persistence |
|-------------|-------------|---------------------------|-------------|
| Earnings surprise (beat/miss) | Actual EPS vs consensus | 3-8% post-event drift | 60-90 days (PEAD) |
