ABSTRACT
We use frequency-domain techniques, namely wavelets and cross-spectra, to examine the association between the daily prices of crude oil futures and daily S&P 500 futures closing prices over the past several decades. We investigate contemporaneous and lag-lead relationships in levels and returns. It is our belief that the wavelet and cross-spectral analyses employed in this paper oer insights regarding the relationship between oil prices and stock returns that are not apparent from a conventional time-domain framework. Our ndings cast doubt on the purported negative relationship between oil and the U.S. stock market. Our analysis suggests that oil prices lead oil volume, and S&P 500 trading volume leads S&P 500 prices.
