老师,请通俗易懂地讲解一下如何理解delta call,万分感谢。我的理解是:delta定义了期权价格对标的资产价格变化的敏感性。那么,(1)为什么delta call = N(d1)呢? N(d1)是到期前的行权概率,如何和delta call产生关系呢?(2)delta call是表示long(short)一份股票,对应short(long)1/delta份的call option吗?同理,long(short)一份call option,对应short(long)delta份股票吗?(3)如何理解N.S/N.C = ∆C/∆S = delta call,这里的N表示什么?
已回答官网Pinnacle Macro Advisers Case Scenario的Q1题Which of Chan’s comments regarding components of the discount rate is most likely correct?B is correct. 没问题。但原文提到的有关折现率的3个关键部分 Morgan mentions to Chan that the uncertainty of future cash flows is reflected by the discount rate, which is composed of three key components. 没看明白?Chan他回答的另外两个不对,那又是什么?

- 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
