Dividend Discount Model (or DDM) is used for valuation of securities of companies based on th eestimated dividend to be declared, the required rate of return and growth rate. The model tries to estimate the intrinsic value of shares of companies by using the requisite rate of return. Accoding to this model
Price of a share = Do(1+g)/(Ke-g)
where Do = Dividend declared by the company for the last year
g = Growth rate
Ke = Required rate of return.
The assumptions of the modle are
1. Dividend is declared at a stable rate
2. Growth rate of the company is constant.
3. Ke is given and constant.
One of the important assumption is constant growth rate, i.e growth rate will remain same during the coming years. However this may be true for typically mature blue-chip companies in well-developed industries, and therefore more useful for valuing these stocks. If the growth rate fluctuates this model cant be applied unless growth rate become constant.
For example
If Do = $ 2 g = 10%, Required rate of return = 15%,
then Price of share (Intrinsic value) = Do(1+g)/Ke - g = 2(1+0.10)/(0.15-0.10) = 2.2 / 0.05 = $ 44.
