It would likely take some time for the inefficiency to converge to efficient valuation. The infrequent nature of the inefficiency and the zero mar-ginal return suggest that the inefficiency is probably not worthwhile to pursue不太理解是什么意思？A和B為什么錯？錯在哪里？

同學你好
下列哪一項與利用結構無效率是可重復的期望是一致的
A說是特別的事件，不頻繁的發(fā)生，所以不可重復
B說gross return等于transaction cost說明marginal return等于零，所以這個時候我加大投資是沒有意義的，因為這種無效性很罕見，不會短期修正，所以不能重復利用
