Bimodal Characteristic Returns and Predictability Enhancement via Machine Learning

چکیده
This paper documents the bimodality of momentum stocks: both high- and low-momentum stocks have nontrivial probabilities for high low returns. The makes strategy fundamentally risky can cause a large loss. To alleviate improve return predictability, this develops novel cross-sectional prediction model via machine learning. By reclassifying based on their predicted financial performance, significantly outperforms off-the-shelf learning models. Tested U.S. market, value-weighted long-short portfolio earns monthly alpha 2.4% (t-statistic = 6.63) when regressed against Fama–French five factors plus short-term reversal factors. was accepted by Kay Giesecke, finance.

Predictability of Returns and Cash Flows ∗ Ralph
We review the literature on return and cash flow growth predictability form the perspective of the present-value identity. We focus predominantly on recent work. Our emphasis is on U.S. aggregate stock return predictability, but we also discuss evidence from other asset classes and countries. JEL classification: G10, G12, G14, G35.
متن کاملEntropy and Predictability of Stock Market Returns¤
We examine the predictability of stock market returns by employing a new metric entropy measure of dependence with several desirable properties. We compare our results with a number of traditional measures. The metric entropy is capable of detecting nonlinear dependence within the returns series, and is also capable of detecting nonlinear\a±nity" between the returns and their predictions obtain...
متن کاملPredictability in International Asset Returns: A Reexamination
This paper argues that inferring long-horizon asset-return predictability from the properties of vector autoregressive (VAR) models on relatively short spans of data is potentially unreliable. We illustrate the problems that can arise by re-examining the findings of Bekaert and Hodrick (1992), who detected evidence of in-sample predictability in international equity and foreign exchange markets...
متن کاملUnderstanding the Predictability of Excess Returns∗
A seminal paper by Fama and Bliss (1987) showed that a simple regression model could explain a significant portion of 1-year ahead excess returns. Cochrane and Piazzesi (2005) showed that their regression model could explain a significantly large portion of excess returns than Fama and Bliss’ model and that a single return-forecasting factor essentially encompassed the predictability of excess ...
