Electrical conductivity in graphite is maximized parallel to the pi framework and parallel to the planar C atom framework. This is because the delocalized pi electrons, which are responsible for the conductivity, are free to move along the layers of the graphite structure. The parallel alignment of the layers maximizes the distance over which the electrons can move, leading to increased conductivity. The perpendicular orientation would limit the movement of these electrons.
