In the space of homogeneous polynomial vector fields of degree two, those that project on Morse-Smale vector fields on ${S^2}$ by the Poincaré central projection form a generic subset. The classification of those vector fields on ${S^2}$ without periodic orbits is given and applications to the study of local actions of the affine group of the line are derived.
