  This study outlines a comprehensive methodology utilizing copulas to discern
inconsistencies in the behavior exhibited by pairs of financial assets. It
introduces a robust approach to establishing the interrelationship between the
returns of these assets, exploring potential measures of dependence among the
stochastic variables represented by these returns. Special emphasis is placed
on scrutinizing the traditional measure of dependence, namely the correlation
coefficient, delineating its limitations. Furthermore, the study articulates an
alternative methodology that offers enhanced stability and informativeness in
appraising the relationship between financial instrument returns.
