Which copula captures the dependence structure of empirical asset returns better? the $t$-copula, which has symmetric tail dependence, or the Clayton copula, which has asymmetric tail dependence, and why? I've seen conflicting advice.

If they're both competitive to one another, how to mix or generate a compromise between the two?

It is no accident that it is called "run FOR the door not INTO the door". That said, every use of parametric copula models is fishy ... $\endgroup$

  • $\begingroup$ @gg are you saying parametric copula are inadequate for modeling the dependence structure of financial returns? $\endgroup$
