Late-Stage Revision Velocity

Overview

This pillar analyzes the velocity and magnitude of analyst earnings estimate revisions in the final two weeks before a company's report. It provides a powerful signal for predicting earnings surprises, as last-minute changes often reflect new information or a shift in expert consensus.

What It Does

Late-Stage Revision Velocity focuses exclusively on the critical 14-day period leading up to an earnings announcement. It quantifies the net direction of estimate changes by comparing the number of upward revisions to downward revisions. The pillar also measures the average percentage change of these revisions to gauge the conviction behind the new estimates, identifying stocks with strong pre-earnings momentum.

Why It Matters

This analysis provides a significant edge by capturing 'whisper numbers' and late-breaking information before it becomes public. While the market prices in the long-term consensus, this pillar focuses on the most recent, and often most accurate, shifts in expert opinion, helping to forecast positive or negative earnings surprises.

How It Works

The process begins by identifying a company's earnings date and collecting all analyst estimate revisions from 14 days prior. We then calculate the ratio of positive to negative revisions and the average magnitude of these changes. Finally, these metrics are combined to generate a velocity score, indicating the strength and direction of the pre-earnings sentiment shift.

Methodology

The primary metric is the Revision Velocity Score (RVS), calculated as: RVS = (Upward Revisions - Downward Revisions) / Total Revisions within a 14-day pre-earnings window. This is weighted by the average percentage change of the revisions. Data is aggregated daily from analyst reports, and only revisions from analysts with a high historical accuracy score are included to filter out noise.

Edge & Advantage

This pillar offers a time-sensitive edge by isolating the most recent analyst sentiment, which is often a leading indicator of an earnings beat or miss that the broader market has not yet priced in.
