When phi is an analytic self-map of the unit disk with Denjoy-Wolff point alpha is an element of D, and rho(W-Psi,W-phi) = Psi(a), we give an exact characterization for when W-Psi,W-phi is normaloid. We also determine the spectral radius, essential spectral radius, and essential norm for a class of non-power-compact composition operators whose symbols have Denjoy-Wolff point in D. When the Denjoy-Wolff point is on partial derivative D, we give sufficient conditions for several new classes of normaloid weighted composition operators.
