Analyst Disagreement Measured and Mapped
Our methodology treats analyst forecast dispersion as a cross-sectional signal, not a curiosity. We document how we collect estimates, quantify disagreement, link it to returns, and validate that the relationship persists out of sample.
Reproducibility First
Every model release includes the full data pipeline, parameter choices, and statistical tests. Users can replicate our work, find our errors, and improve on our approach. We believe model risk is best managed through transparency, not obscurity.
Behavioral Grounding
Dispersion arises because analysts process information differently, face varying incentives, and exhibit documented cognitive biases. Our frameworks incorporate these behavioral mechanisms rather than treating disagreement as a mechanical artifact.
Practitioner Relevance
A model that wins in a journal but fails in a live portfolio helps no one. We design every test with implementation frictions in mind: transaction costs, liquidity constraints, and the practical limits of forecast data availability.
How We Build Models
A rigorous pipeline from raw analyst estimates to validated cross-sectional signals. Each stage is documented, testable, and open to scrutiny.
Data Collection
Aggregate analyst earnings estimates from multiple sources to build a comprehensive, point-in-time database of forecasts.
The Goal
Capture the full distribution of analyst opinions at each reporting date without look-ahead bias or survivorship distortion.
What We Do
We collect individual analyst estimates for earnings per share, revenue, and other key metrics across coverage universes. Each estimate is time-stamped and linked to the analyst and brokerage to track coverage changes.
How We Do It
The Tools
Python pipelines, SQL databases, automated validation scripts, manual audit sampling.
Deliverables
A point-in-time database of analyst estimates with full provenance and error flags.
Dispersion Calculation
Transform raw estimates into standardized disagreement metrics that capture different dimensions of analyst divergence.
The Goal
What We Do
We compute standard deviation, interquartile range, coefficient of variation, and more nuanced behavioral measures like skewness of the forecast distribution and the gap between optimistic and pessimistic analyst clusters.
How We Do It
Each metric is calculated over a fixed analyst window to avoid bias from coverage changes. We winsorize extreme values and document how each transformation affects the resulting distribution.
The Tools
R statistical environment, custom dispersion libraries, visualization dashboards for distribution checks.
Deliverables
A panel of dispersion metrics with documented formulas, parameter choices, and sensitivity analyses.
Return Linkage
Test whether dispersion metrics predict subsequent cross-sectional price movements using regression and portfolio sort designs.
The Goal
Establish whether high or low dispersion forecasts future returns, controlling for known risk factors and market conditions.
What We Do
How We Do It
Models are estimated on rolling windows to simulate real-time application. We report full coefficient paths, standard errors, and diagnostic statistics rather than cherry-picking favorable subperiods.
The Tools
Deliverables
Regression tables, portfolio return series, factor attribution breakdowns, and subperiod robustness checks.
Out-of-Sample Validation
Validate model predictions on data not used in the original construction to assess real-world applicability.
The Goal
Ensure that observed in-sample relationships are not the product of overfitting or data mining.
What We Do
How We Do It
The Tools
Holdout datasets, recursive estimation engines, structural break tests, regime-switching models.
Deliverables
Out-of-sample performance reports, break date estimates, and regime-specific return decompositions.
Documentation and Release
Package every model into a documented, replicable format that practitioners can adopt, critique, and extend.
The Goal
What We Do
Each release includes a methodology whitepaper, replication code, sample data, and a plain-language summary. We explain not just what works, but what failed and why.
How We Do It
Documentation is reviewed by both research staff and external practitioners before release. Code is commented and tested on clean environments to ensure portability.
The Tools
Version control systems, reproducible research environments, peer review workflows, user feedback loops.
Deliverables
Forecast Dispersion
The standard deviation of analyst earnings estimates captures how widely opinions diverge. High dispersion often signals uncertainty, information asymmetry, or fundamental disagreement about a company's trajectory. In cross-sectional tests, this measure predicts future returns even after controlling for standard risk factors.
Recommendation Spread
Beyond earnings estimates, analysts issue buy-hold-sell recommendations. When these recommendations cluster at extremes rather than consensus, the spread reveals divergent conviction. Our models track how recommendation dispersion interacts with forecast dispersion to strengthen or weaken predictive signals.
Surprise Dispersion
Not all analysts miss earnings by the same amount. The cross-sectional dispersion in earnings surprises — how scattered the errors are — reflects the predictability of the underlying business. High surprise dispersion predicts future return volatility and can flag companies where analyst models are systematically mis-specified.
Behavioral Roots
Dispersion does not emerge randomly. Analysts exhibit herding, overconfidence, and asymmetric loss functions. Our frameworks link these documented behavioral biases to the shape of forecast distributions, helping users distinguish between healthy disagreement and systematic cognitive distortion.

Why We Document Everything
Academic finance has known about dispersion effects for decades. Practitioners largely ignored them because the research sat behind paywalls and impenetrable notation. Our philosophy is simple: translate that rigor into usable tools, then prove they work with ongoing tests.
