Guidance 'Sandbag' Coefficient

Overview

This pillar analyzes a company's history of issuing conservative financial guidance to determine the likelihood they are 'sandbagging'. It helps traders identify companies poised to easily beat expectations, creating a potential trading opportunity.

What It Does

The model systematically compares a company's past earnings and revenue guidance against its actual reported results. It identifies consistent patterns of under-promising and over-delivering. The analysis is weighted by recency and adjusted for factors like CEO tenure and overall industry trends to produce a single coefficient.

Why It Matters

Management guidance heavily influences market expectations. By identifying a high 'sandbag' coefficient, traders can gain an edge, predicting an earnings beat even when consensus estimates are aligned with the conservative guidance.

How It Works

First, the pillar ingests 8 to 12 quarters of historical guidance and actual results for a specific company. It then calculates the percentage delta for each period. These deltas are then aggregated into a time-weighted average, which is further refined by a factor accounting for the current CEO's historical bias, generating the final coefficient.

Methodology

The coefficient is calculated as the time-weighted average of (Actual EPS / Midpoint Guidance EPS - 1) over the past 12 quarters. Quarters are weighted using an exponential decay function with a half-life of 4 quarters. The result is multiplied by a CEO/CFO tenure adjustment factor, which regresses to 1.0 for new management and is based on their personal track record at the company.

Edge & Advantage

It provides a data-driven signal to position against consensus when management has a proven history of understating performance, an edge the market often misprices before an earnings report.
