Time–frequency relationship between share prices and exchange rates in India: Evidence from continuous wavelets

The paper examines the relationship between exchange rates and share prices using the wavelets approach, and more specifically the continuous wavelet power spectrum, cross-wavelet transform, and cross-wavelet coherency. Our results, based on Indian data, lend support to the traditional (Am Econ Rev 70:960–971, <CitationRef CitationID="CR13">1980</CitationRef>) as well as the new portfolio hypothesis (Am Econ Rev 83:1356–1369, <CitationRef CitationID="CR15">1993</CitationRef>), albeit over different time periods and across different time scales. The wavelet approach used in the paper has helped to uncover some interesting economic relationships within the time–frequency domain which have remained hidden thus far.
