Being a ball-and-socket joint, it allows movements in three degrees of freedom (average maximum glenohumeral active RoM is shown in brackets); Combination of these movements gives circumduction. (2020). Available from: Laitung JK, Peck F. Shoulder function following the loss of the latissimus dorsi muscle. 2000 Jan;44(1):18-22. This incongruent bony anatomy allows for the wide range of movement available at the shoulder joint but is also the reason for the lack of joint stability.
