问题如下:

7. Based on the relationship between the implied growth rate and the sustainable growth rate, Peters’ team should conclude that Company JZY’s stock price is most likely:

选项:

A.

undervalued.

B.

fairly valued.

C.

overvalued.

解释:

C is correct.

The sustainable growth rate of JZY stock = g = Retention ratio × ROE = 0.60 × 0.0817 = 4.9%. JZY stock’s implied growth rate of 5.3% is higher than the sustainable growth rate of 4.9%. Consequently, the stock is overvalued—that is, the intrinsic value of the stock will be less than its current market price. The current intrinsic value of JZY stock is as follows:

V0 = [D0(1 + g)]/(r g)

= [0.84 (1.0490)]/(0.08 – 0.0490)

= US$28.42 < US$32.76.

如何根据b和d来推导g?

同学你好,b是retention ratio,d是分红或分红比率。

但是b和d是推导不出g的呢。或者你想问的是g=ROE*b这个公式?

如果是的话,同学可以看下以下推导,但是这个推导老师上课的时候也说过只是作为参考,原版书并没有相关内容,同学仅供参考哦

首先,这个公式有两个前提,一是留存收益率b保持不变

第二个前提,公司的资本结构始终保持不变

利润留存 = 税后经营净利润*留存率 = NI*b

由于分红增长率g保持不变,所以NI就必须以g的速度增长才能使分红始终以g的速度增长,而equity的唯一来源是留存收益,所以最后equity也以g的速度增长

所以NI*b = Equity*g

变换公式就有NI/Equity * b =g,由于NI/equity = ROE ,所以ROE*b = g
