We investigate the infra-red stability of the fixed points in the evolution of the Yukawa couplings, A-parameters and soft scalar masses in a broad class of supersymmetric theories. We show that the issue of stability is essentially determined in all three cases by the eigenvalues of the same matrix. In a very wide range of physically interesting theories it follows that, in the asymptotically free case, the existence of stable infra-red fixed points for the Yukawa couplings implies stable infra-red fixed points for the A-parameters and soft scalar masses. © 1998 Elsevier Science B.V.
