Dividend Discount Model Limitations

This question practices a core valuation concept, understanding when the dividend discount model is useful and when it breaks down. Candidates need to know why the model is highly sensitive to assumptions about dividend growth and required return, why it works best for mature companies with stable payout histories, and why it is often unsuitable for firms that reinvest cash, repurchase shares, or do not pay dividends at all. Interviewers ask this because they want to see whether you can judge the appropriateness of a valuation method, not just recite formulas. In banking interviews, that judgment matters because the best valuation approach depends on the company’s capital allocation policy, stage of growth, and the reliability of the inputs.
