Thanks all, great comments. My view is different and that the cost basis of the shares owned is not relevant (except for tax purposes). If the goal is to seek to profit-maximise from each moment looking forward, then whether you bought CBA shares at $10, $22 or $89, the profit-maximising course of action on each day looking forward should be the same under all scenarios (again, leaving tax aside). Hope I am making sense. All the best, -AM
