We derive a formula for the anisotropic density distribution around haloes and voids on large scales. Our model assumes that the orientation of non-linear structures is strongly correlated with the Lagrangian shear, and gives a qualitative understanding of the recent detection of an enhanced clustering signal along the major axis of haloes. We also show that the measured amplitude is inconsistent with a model in which the alignment is produced by the initial inertia rather than shear tensor.
