Bow balance point (centre of mass) needs to be as far from the grip (pivot point) as feasible. Mainly forward of grip but also below the grip. Limitations are overall weight bowhand has to support and stifffness of stabiliser. Many write ups do suggest that cog should be level with or even at the grip e.g. Archery Anatomy. These descriptions are mechanically incorrect

Having cog level with the grip is bad, above the grip is a disaster. - never raise the bow cog e.g. stabiliser in top bushing is a definite no-no.
