Abstract
The recently established saddle-point instability of the effective potential for composite operators in QCD-like theories is shown here to be removable by choosing a modified but equivalent form for the effective potential. This form has been proposed by Casalbuoni, De Curtis, Dominici, and Gatto.Keywords
