This paper examines the relationship between Indian equity prices other developed
markets, in the time-scale domain, using wavelets based multiscale analysis and cross wavelet
analysis. Stock markets are analyzed at different levels of resolution which makes it possible to
perform a scale by scale analysis enabling us to detect the correlation and cross-correlation
structures at time periods with high frequency oscillations and also the relatively low frequency
structures. There seems to be a weak integration between BSE and other developed markets at
almost all levels of time-scale resolution and a strong relationship between French and German
Markets. Analyzing the stock returns at different multiscale resolution makes it easier for agents
dealing with different trading horizons
