A condition is derived for the secular stability of a contact binary in which the components share a common convective envelope. For a large class of models, this stability condition cannot be satisfied when the adiabatic constants of the two stellar convection zones differ by more than a certain small amount. A consequence is that the contact binary models of Biermann and Thomas, Moss and Whelan (1973) and Vilhu are unstable. The existence of such an instability may account for the distinct lack of short period eclipsing variables with beta Lyrae type light curves.
