It is hypothesized in this study that the relationship between institutional ownership and inventory anagement is more likely to be moderated by other internal corporate governance mechanisms (i.e., managerial ownership, board leadership structure and board size). This is more likely to happen as one weak governance mechanism in one area will be offset by a strong one in another area. Furthermore, the effectiveness of one corporate governance mechanism (i.e., institutional ownership) is more likely to be contingent on some contextual variables. Econometric analysis, using a sample of Egyptian listed firms, provides strong evidence for the applicability of this theme and demonstrates that institutional ownership affects inventory management positively (negatively) when managerial ownership is high (low), CEO duality (non-duality) is in place, or board size is large (small). This conclusion is robust to the use of different control variables and econometric models
