输入预期每股股利 D₁、要求收益率 r 与股利增长率 g,求合理股价。
| Item | Formula / Rule | Source / Standard |
|---|---|---|
| Valuation formula | P = D1 / (r − g) with D1 = D0 × (1 + g) | Gordon & Shapiro 1956, Management Science 3(1) |
| Parameter sensitivity | The closer r and g, the more sensitive value is to small changes, diverging as the gap closes | Gordon & Shapiro 1956, Management Science 3(1) |
| Scope of use | It suits firms with steadily growing dividends; non-payers or volatile firms need discounted cash flow instead | Williams 1938, The Theory of Investment Value |
