Company is planning to pay a dividend of 5\$ per share (dividend for previous year). Investor that wants to buy a shares of this company assumes that dividend will be stable (Thus will not change in future). What is the maximum price that investor can pay for one share, assuming that he will receive a right for dividend for a previous year and expected rate of return is equal to at least 9.5%?

My attempt was to use gordon's formula i.e. $\frac{D_1}{r-g}=P_0$: $$\frac{5}{0.095}+5\approx57.63\$ $$ Is it correct?

  • $\begingroup$ What I can say is that the approximated equation is not correct: $57.63\%=0.5763$. You also should say what thoughts are behind your calculation. $\endgroup$ Dec 14, 2015 at 20:09
  • $\begingroup$ Dividend divided by rate of return, plus dividend from the previous year (as it was not included). Formula is from gordon's model $\frac{D}{r-g}=P$ $\endgroup$ Dec 14, 2015 at 20:33
  • $\begingroup$ As written in the answer of Justpassingby your solution seems right. $\endgroup$ Dec 14, 2015 at 20:38
  • $\begingroup$ But what i do not understand what for he mentioned this geometric series of dividends. If my answer is correct what is the point of calculations shown? $\endgroup$ Dec 14, 2015 at 20:41

Your formula, $\frac{D}{r-q}$, is the value of the sum of growing dividends. This dividends are payed for infinitely periods. But in your case the dividends do not grow. Therefore $g$ is equal to $1$: $\frac{D}{r-1}$.

$r=1+i=1.095$, where i is the interest rate.

Calculating the future value of the dividends

The first dividend has to be compounded n-1 times to get the future value of this dividend: :$Dr^{n-1}$

The second dividend has to be compounded n-2 times to get the future value of this dividend:$Dr^{n-2}$

The n-th dividend has not to be compunded to get the future value of this dividend: :D

The sum of These compunded dividends after n years is

$S_n=D+Dr+Dr^2+\ldots Dr^{n-2}+Dr^{n-1}$

$S_n=D\left(\color{red}1+\color{blue}{r+r^2+\ldots r^{n-2}+r^{n-1}} \right) \quad (1)$

The term in the brackets is the partial sum of a geometric series.

multiplying the equation by r

$rS_n=D\left(\color{blue}{r+r^2+\ldots r^{n-2}+r^{n-1}}+\color{red}{r^n} \right) \quad (2)$

Substract 2 from 1. The blue terms are equal. They neutralize each other.


Factor out $S_n$ on the LHS



To get the present value $S_n$ has to be divided by $r^n$

$\frac{D(1-r^n)}{r^n}\cdot \frac{1}{1-r}$

$D\left(\frac{1}{r^n}-1\right)\cdot \frac{1}{1-r}$

Now you assume that the dividends are payed for infinitely periods. Thus n goes to infinity.

$\lim_{n \to \infty} D\left(\frac{1}{r^n}-1\right)\cdot \frac{1}{1-r}$

$=D(0-1)\cdot \frac{1}{1-r}=\frac{D}{r-1}=\frac{D}{1+i-1}=\frac{D}{i}$

The present value of the infinitely times payed dividends is

$\frac{\$ 5}{0.095}\approx \$52.63$

The investor also gets $\$5$ for the previous dividend. Thus the maximum price the investor is willing to pay is $\$52.63+\$5=57.63$

Yes, your answer is correct.


That seems correct. The $\$5$ additional dividend just add to the price so let us concentrate on the net present value of all present and future dividend, that is the geometric series
