RT Journal Article SR Electronic T1 Enhanced Mean–Variance Portfolios:
A Controlled Integration of Quantitative Predictors JF The Journal of Portfolio Management FD Institutional Investor Journals SP 28 OP 41 DO 10.3905/jpm.2014.40.4.028 VO 40 IS 4 A1 Lars Kaiser A1 Marco J. Menichetti A1 Aron Veress YR 2014 UL https://pm-research.com/content/40/4/28.abstract AB The intuitiveness and practicality of mean–variance portfolios largely depend on the accuracy of moment estimates, which are subject to large estimation errors and are conditional on time. The authors propose a model that accounts for factor dynamics in a Bayesian setting, in which they endogenously derive the effect of estimation accuracy on the posterior distribution from a linear predictive regression model. By doing so, they capture upside return potential for periods of high factor-explained variance, while constraining downside risk for periods of low predictive quality. Results are robust in a simulation and an empirical setting.TOPICS: Portfolio construction, statistical methods, performance measurement
