In this paper, we have examined the Sharma–Mittal holographic dark energy model (SMHDE) in the framework of an isotropic and spatially homogeneous flat Friedmann–Robertson–Walker Universe by considering different values of parameter and R, where the infrared cut-off is taken care by the Hubble horizon. We examined the SMHDE model through the analysis of statefinder hierarchy and the growth rate of perturbation. The evolutionary trajectories of the statefinder hierarchy , , versus redshift z, show satisfactory behaviour throughout the Universe evaluation. One promising tool for investigating the dark energy models is the CND and , where the evolutionary trajectories of the and pair present different properties and the departure from could be well evaluated. Additionally, we investigated the dynamical analysis of the model by pair analysis.
