Abstract We investigate the role of internal corporate governance in limiting opportunities for ASX company ‘insiders’ to extract abnormal returns from trading ‘own shares’. We show that stronger governance translates into more restrictive insider trading policies and, while not resulting in lower insider purchase volumes, values or profits, it does reduce insider selling profitability. Firm size and increasing trading policy restrictiveness is associated with reduced insider purchase profitability while insider sale profitability is reduced by aggregate governance, trading restrictions and increasing trading policy restrictiveness. We conclude that internal firm governance constrains insider sales but not purchases, providing contrarian trading signals.
