Answer: True
Explanation: The Dividend Discount Model (DDM) is a quantitative method that is used in valuing a company's stock price based on the assumption that the current fair price of a stock is equal to the sum of all of the company's dividends in the future.
The Dividend Discount Model assumes that a dividend will grow constantly indefinitely. This assumption is safe for companies that are very mature and have an established history of regular dividend payments.
However, this model may not really be the suitable model to be used in valuing companies that are new and which have dividend growth rates that are fluctuating or have no dividend at all.
