Abstract: We investigate the time-scale relationships between US equity and commodity markets. The empirical evidence from the risk-return profitability analysis based on the wavelet coherence measure shows that equity and commodity markets exhibit time-varying co-movement patterns and behave differently across investment horizons. Moreover, we find evidence of time-frequency causality between the two investigated markets. Our results can have important implications for optimal asset allocation and portfolio diversification.
