老师 讲义上第一条不是说 price cannot <0, so price has a lognormal distribution, but return could be negative, therefore return is normally distributed. 而这一点一级的时候也是这么说的,但这题B选项为什么要说 return is lognormal distribution 呢
当收益率曲线非平行移动时只能用KDR去拆,那就是说如果是平行移动的话可以用正常duration去拆,对吗?但是平行移动的时候如果这么拆就会得到portfolio的duration就是单个duration的简单求和呀,这显然不对,怎么解释?
精品问答
- Q3:解析里面Team Purple’s conclusion (the externalities associated with human capital is the most important determinant in predicting the occurence of convergence) implies that the production function is a straight line, and is compatible with non-convergence.这段话中 externalities associated with human capital具体是什么?怎么得到the production function is a straight line这个结论呢?
- Growth due to capital deepening 是αΔK/K还是ΔK/K
- 这题为什么是选C?
- 请老师讲解一下这个题目
- 老师,第二题可以在解释一下原理吗?
- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
- CDS的long和short是不是反过来的?就是long CDS代表看涨目标公司credit,所以是卖出一份CDS合约?
- 很迷惑到底是long call+ short stock还是long stock+short call构建无风险资产
