Overshooting the Coordinate: Where Factor Corrections Land on Characteristic Axes

Useong Shin

The paper proposes a characteristic‑axis diagnostic that maps model alphas to see how factor corrections affect pricing errors along specific characteristics, finding that differen…

A Cap-Axis Integral Diagnostic of Factor Models

Useong Shin

I propose a cap-axis zero-alpha diagnostic for factor-model evaluation. Whole-stock capitalization prefixes are paired with equal realized exposure to the aggregate market, produci…

Anatomy of the Market: A Body-Tail Test of Factor Models

Useong Shin

In an ideal stochastic discount factor, zero pricing errors and maximum Sharpe ratio coincide; in a low-dimensional approximation they need not. I test this separation by decomposi…

Which Portfolios? The Construction Dependence of Factor Model Performance

Useong Shin

Factor-model performance depends not only on the model but also on how test assets are constructed. We form characteristic-unsorted random portfolios from a broad CRSP universe and…

A Three-Variable Benchmark for Post-GFC Covered Interest Parity Deviations

Useong Shin

This paper proposes a public daily-frequency benchmark for post-GFC government-bond CIP deviations. Although CIP deviations are observed daily, the literature lacks a canonical ben…

The P behind Q: Empirical Evidence from Physical Drift in Put-Call Parity

Useong Shin

Put-call parity is a terminal-payoff identity, but its enforcement is capital-using. I study the carry gap, the annualized wedge between option-implied and OIS discount factors, in…
