The Gordon Growth Model is a popular method used in finance to determine the intrinsic value of a stock. This model, also known as the Dividend Discount Model, assumes that dividends will continue to grow at a constant rate indefinitely. It simplifies the valuation process by focusing on expected future dividends and the growth rate of those dividends. The formula used is:

• \( P_0 = \frac{D_1}{r_s - g} \)

Where \( P_0 \) is the price of the stock, \( D_1 \) is the expected dividend in the next year, \( r_s \) is the required rate of return, and \( g \) is the growth rate of the dividends. When applying this model, it is crucial that the growth rate \( g \) is less than the required return \( r_s \) to provide a meaningful result.
The Gordon Growth Model is especially useful for companies that pay regular and steady dividends, such as utility or blue-chip stocks. Investors use this model to estimate whether a stock is overvalued or undervalued based on the potential future cash flows (dividends) it will generate.

In the context of the Gordon Growth Model, the constant growth rate represents the expected increase in dividends per year. This growth rate is crucial because it affects the valuation of the stock directly. If dividends are expected to grow consistently, they reflect the potential earnings and profitability growth of a company.
The assumption of a constant growth rate simplifies stock valuation but does require realistic expectations. Generally, it should be sustainable and lower than the required rate of return to produce sensible results. For example, in practice:

• A constant growth rate of 3-5% might be feasible for stable, established companies.
• A rate higher than the required return is not realistic as it implies dividends grow perpetually faster than investors demand returns.

Investors must adjust their assumptions if a company's growth expectations change, making the constant growth model an adaptable yet precise tool for stock valuation.

Stock valuation is the process of determining the worth of a stock based on expected future dividends flowing to the investor. The Gordon Growth Model is a common approach for this, especially for firms with stable dividends.
In stock valuation, understanding the current dividend, future dividends, growth rate, and required rate of return is essential. Here's how you would typically use this model:

• Calculate the expected dividend for the next year: \( D_1 = D_0(1+g) \).
• Determine the required rate of return \( r_s \).
• Substitute these into the Gordon model to find \( P_0 \).

For example, if a stock with a previous dividend (\( D_0 \)) of $2 is expected to grow by 5% each year and investors require a 15% return, the valuation will differ significantly compared to a scenario where dividends grow by 10%. Different growth rates show how sensitive stock valuation is to assumptions about future growth. This approach aids investors in making informed decisions about buying or selling stocks based on intrinsic value.

The required rate of return represents the minimum annual percentage return investors expect to earn from an investment, compensating for its risk level. In stock valuation, it's crucial because it serves as a benchmark for evaluating whether a stock is worth purchasing.
In the Gordon Growth Model, the required rate of return \( r_s \) forms a critical component of the calculation. It is what investors demand to hold a stock given its risk profile. The required return can vary based on factors such as:

• Market conditions.
• Investor risk tolerance.
• Company-specific risk factors.

It must exceed the dividend growth rate \( g \) to ensure that the Gordon Growth Model provides a finite and rational stock price. If \( g \) were higher, it would imply that dividends grow indefinitely at a faster rate than investors expect to recover as returns, which is impractical and unrealistic in the real world. Thus, precise estimation of the required rate of return is key to reliable stock valuation.
