Trading-hour and nontrading-hour volatility in crude oil and U.S. dollar markets and its implications for portfolio optimization

Abstract

The covariance between crude oil prices and U.S. dollar exchange rates is crucial for energy investors, and stock prices differ between trading and nontrading hours. Thus, the present study uses a two-component generalized autoregressive conditional heteroskedasticity (GARCH) model to analyze whole-day returns. Our analysis of data from 2007 to 2021 reveals that trading-hour and nontrading-hour returns contain crucial information for modeling whole-day covariance. Additionally, out-of-sample portfolio comparisons indicate that a two-component model is more effective than simpler models for portfolio optimization, resulting in substantial basis point fees when switching from the static to the two-component model. Crucially, the economic value generated by the two-component model is not offset by reasonable transaction costs; more risk-averse investors can generate higher benefits.
