3.3.1 Dividend Discount Models
The Dividend Discount Model (DDM) is a fundamental valuation approach used to determine the intrinsic value of a stock based on its expected future dividends. This model is particularly relevant for investors focusing on dividendpaying stocks, as it provides a framework for assessing the present value of expected cash flows from dividends. In this section, we will delve into the principles of DDM, explore its calculations, discuss its underlying assumptions, and illustrate its application through examples.
Principles of the Dividend Discount Model
The core principle of the Dividend Discount Model is that the value of a stock is the present value of all its future dividend payments. This approach aligns with the broader concept of discounted cash flow (DCF) analysis, where future cash flows are discounted back to their present value using a required rate of return. The DDM is particularly suited for companies with a history of paying dividends and a predictable dividend policy.
Calculating Intrinsic Value Using DDM
The intrinsic value of a stock using the DDM can be calculated using the Gordon Growth Model, a simplified version of the DDM. The formula is as follows:
$$ P = \frac{D₁}{r  g} $$
Where:
 \( P \) is the intrinsic price of the stock.
 \( D₁ \) is the expected dividend in the next year.
 \( r \) is the required rate of return.
 \( g \) is the dividend growth rate.
This formula assumes that dividends will grow at a constant rate indefinitely. The Gordon Growth Model is particularly useful for mature companies with stable dividend growth rates.
Assumptions Underlying the DDM
The Dividend Discount Model relies on several key assumptions:

Constant Dividend Growth: The model assumes that dividends will grow at a constant rate indefinitely. This assumption is more applicable to mature companies with stable earnings and dividend policies.

Stable Required Rate of Return: The required rate of return, which reflects the investor’s opportunity cost, is assumed to remain constant over time.

Dividend Payments: The model is applicable primarily to companies that pay regular dividends. For companies that do not pay dividends, alternative valuation models are more appropriate.

Infinite Time Horizon: The model assumes an infinite time horizon for dividend payments, which may not be realistic for all companies.
Illustrating the Use of Constant Growth and MultiStage DDM
Constant Growth Model Example
Consider a company, ABC Corp, which is expected to pay a dividend of $2 per share next year. The dividends are expected to grow at a rate of 5% per year, and the required rate of return is 10%. Using the Gordon Growth Model, the intrinsic value of ABC Corp’s stock is calculated as follows:
$$ P = \frac{2}{0.10  0.05} = \frac{2}{0.05} = \$40 $$
This calculation suggests that the intrinsic value of ABC Corp’s stock is $40 per share.
MultiStage DDM Example
For companies experiencing varying growth phases, a multistage DDM is more appropriate. This model involves dividing the dividend growth into different stages, each with its own growth rate.
Consider XYZ Corp, which is expected to pay a dividend of $1 per share next year. The dividends are expected to grow at 8% for the first three years, then stabilize at a 4% growth rate. The required rate of return is 9%.
Stage 1: High Growth Phase (Years 13)
$$ D₁ = 1 \times (1 + 0.08) = 1.08 $$
$$ D₂ = 1.08 \times (1 + 0.08) = 1.1664 $$
$$ D₃ = 1.1664 \times (1 + 0.08) = 1.26 $$
Stage 2: Stable Growth Phase (Year 4 and beyond)
$$ D₄ = 1.26 \times (1 + 0.04) = 1.3104 $$
The present value of dividends for the first three years is calculated as follows:
$$ PV = \frac{1.08}{(1 + 0.09)^1} + \frac{1.1664}{(1 + 0.09)^2} + \frac{1.26}{(1 + 0.09)^3} $$
The present value of dividends from year 4 onwards is calculated using the Gordon Growth Model:
$$ P_3 = \frac{1.3104}{0.09  0.04} = \frac{1.3104}{0.05} = 26.208 $$
The present value of \( P_3 \) is then discounted back to the present value:
$$ PV_3 = \frac{26.208}{(1 + 0.09)^3} $$
The sum of the present values of all dividends gives the intrinsic value of XYZ Corp’s stock.
Estimating Growth Rates and Required Returns
Estimating the growth rate (\( g \)) and required rate of return (\( r \)) is crucial for accurate DDM calculations. The growth rate can be estimated based on historical dividend growth, industry averages, or companyspecific factors. The required rate of return can be estimated using models like the Capital Asset Pricing Model (CAPM), which considers the riskfree rate, the stock’s beta, and the market risk premium.
Applicability and Challenges of DDM
The Dividend Discount Model is most applicable to companies with a consistent dividend policy and predictable growth rates. However, it faces challenges when applied to companies that do not pay dividends or have volatile dividend policies. Additionally, the model’s sensitivity to input variables, such as the growth rate and required rate of return, can lead to significant variations in the calculated intrinsic value.
Advantages and Limitations of DDM
Advantages
 Simplicity: The DDM provides a straightforward approach to valuing dividendpaying stocks.
 Focus on Cash Flows: The model emphasizes the importance of cash flows in the form of dividends, aligning with the interests of incomefocused investors.
 LongTerm Perspective: The model’s infinite time horizon encourages a longterm investment perspective.
Limitations
 Assumptions of Constant Growth: The assumption of constant growth may not hold for all companies, particularly those in dynamic industries.
 Sensitivity to Inputs: Small changes in the growth rate or required rate of return can lead to significant variations in the calculated intrinsic value.
 Limited Applicability: The model is not suitable for nondividendpaying companies or those with irregular dividend policies.
Conclusion
The Dividend Discount Model remains a valuable tool for investors seeking to assess the intrinsic value of dividendpaying stocks. By understanding its principles, calculations, and assumptions, investors can make informed decisions and evaluate the potential returns from dividendfocused investments. However, it is essential to recognize the model’s limitations and consider alternative valuation methods when necessary.
