经济百题Q81 C选项 意思是银行用来可贷款的储备金减少,没有钱可以借出去了,经济有事下行状态,这个时候采取QE,直接将货币注入市场上类似MBS这种,而不是通过银行再放贷给民众,是这个意思吗? A选项,QE不是帮忙解决流动性陷阱问题,而是因为货币政策容易出现流动性陷阱,所以采取QE的货币政策直接解决经济下行问题。 我这么理解AC选项对吗?
已回答老师您好,关于上午真题Derivative部分2017年第十题(D)小问,答案中提到information ratio can be false positive when returns are below risk free rate, 但standard deviation不是应该一直都是正数么?(Rp-Rb)的standard deviation可以是负的吗? 谢谢!
已回答Jensen‘s alpha不是actual portfolio return跟risk-adjusted return之间的差么,那risk-adjusted return要越大的话不应该是alpha越小么
MPS , 等额偿付本金和利息 1.CMOs are created from pools of pass-through securities, 利息和本金有先后顺序 不知我的理解对不? 2.CMOs are securities issued against pass-through securities for which the cash flow have been reallocated to different tranches.这句话如何理解?谢谢!
已回答请问答案解析中A is incorrect because the forward price is set in the pricing of the contract such that the starting contract value is zero, unlike contingent claims, under which parties can select any starting value这句话的意思能解释一下吗,什么是starting contract value?以及为何option中参与方能够选择任何starting value
