For a mapping class on a punctured surface, we prove that the pseudo-Anosov property is equivalent to the sign stability introduced in [IK19]. In particular we conclude that the algebraic entropies of the $mathcal{A}$- and $mathcal{X}$-cluster transformations induced by a mutation loop given by a pseudo-Anosov mapping class both coincide with its topological entropy.
