题目的第一句话是什么意思?

NO.PZ2023032701000051

问题如下:

Baker informs Covey that the highest and lowest reasonable alternative estimates of the valuation model parameters are as follows: 15% for beta, 20% for equity risk premium, and 25% for growth rate. He asks Covey to perform a sensitivity analysis for each of these parameters while keeping all other inputs at the base case level. Covey’s results are shown in Exhibit 2.

Exhibit 2 Sensitivity Analysis to Model Parameters in Valuation of Wadgett’s Common Shares

Note: The risk-free rate is 1.2% in all cases.

Using the data in Exhibit 2, the parameter that causes the greatest sensitivity in valuing Wadgett’s common shares is the:

选项:

A.

beta

B.

growth rate

C.

equity risk premium

解释:

When the low/high measure of each variable is tested singly for sensitiv­ity in predicting a range of intrinsic value while holding the other variables at the base case, the equity risk premium variable produces the largest stock price range, as shown in the following table.

Baker informs Covey that the highest and lowest reasonable alternative estimates of the valuation model parameters are as follows: 15% for beta, 20% for equity risk premium, and 25% for growth rate.


这个可以理解为这三个变量的最高和最低值的平均值为15%、20%和25%吗?还有这三个值跟下面表格有什么关联吗?

同学你好,这句话的意思是,假设base case下beta =A, equity risk premium=B, and growth rate=C,那给到β的最低和最高的两档假设,分别是A*(1-15%)和A*(1+15%);对equity risk premium的最低和最高的两档假设应该分别是B*(1-20%)和B*(1+20%);对growth rate的最低和最高的两档假设应该分别是C*(1-25%)和C*(1+25%)

而下面的表格,以第二行FCFE growth rate为例,就是在假设growth rate等于A*(1-15%)而其他equity risk premium和β都是用base case计算得到的per-share valuation with low estimate的公司估值;同样,后面的per-share valuation with high estimate的公司估值,就是在假设growth rate等于A*(1+15%)而其他equity risk premium和β都是用base case的情景下计算得到的

其他表格的数据,也是以此类推得到的

至于本题的A、B、C的base case到底是多少,其实题目没有说,我们只需要知道15% for beta, 20% for equity risk premium, and 25% for growth rate.就是每个假设输入变量的最低和最高值计算用的变化范围
