  In this work we analyse the stability of self gravitating spheres in the
context of gravitational cracking. Besides exploring the role played by the
anisotropy in the occurrence of cracking, we also study the effect of the
complexity factor recently introduced by L. Herrera in Phys. Rev. D 97, 044010
(2018). The models under study correspond to anisotropic solutions obtained in
the framework of the Gravitational Decoupling. The effect that the variation of
the decoupling parameter and the compactness of the source have on the
behaviour of the radial force is studied in detail.
