Small-sample tests for stock return predictability with possibly non-stationary regressors and GARCH-type effects

Gungor, Sermin; Luger, Richard - 2017

We develop a simulation-based procedure to test for stock return predictability with multiple regressors. The process governing the regressors is left completely free and the test procedure remains valid in small samples even in the presence of non-normalities and GARCH-type effects in the stock...

A higher-order correct fast moving-average bootstrap for dependent data

La Vecchia, Davide; Moor, Alban; Scaillet, Olivier - 2020

We develop theory of a novel fast bootstrap for dependent data. Our scheme deploys i.i.d. resampling of smoothed moment …-applied first- and higher-order correct methods. The results provide numerical evidence that the novel bootstrap yields higher …

Portfolio Efficiency Tests with Conditioning Information - Comparing GMM and GEL Estimators

Vigo Pereira, Caio - 2020

We evaluate the use of Generalized Empirical Likelihood (GEL) estimators in portfolio efficiency tests for asset pricing models in the presence of conditional information. Estimators from GEL family present some optimal statistical properties, such as robustness to misspecification and better...

Event Study Analysis with Time-Varying Alphas, Betas and Variances : The Case of M&As

Irani, Mohammad (Vahid) - 2020

This paper proposes a new approach to control the effects of time-varying parameters on the estimates of abnormal returns. Event studies usually assume that the parameters of the market model are stable. Using a sample of firm takeovers, however, I find that this assumption is indeed rejected....

Identification-Robust Estimation and Testing of the Zero-Beta CAPM

Beaulieu, Marie-Claude - 2011

We propose exact simulation-based procedures for: (i) testing mean-variance efficiency when the zero-beta rate is unknown, and (ii) building confidence intervals for the zero-beta rate. On observing that this parameter may be weakly identified, we propose LR-type statistics as well as...
