As companies evolve, certain factors can drive sudden growth. This may lead to a period of nonconstant, or variable, growth. This would cause the expected growth rate to increase or decrease, thereby affecting the valuation model. For companies in such situations, you would refer to the variable, or nonconstant, growth model for the valuation of the company's stock. Consider the case of Portman Industries: Portman Industries just paid a dividend of $1.68 per share. The company expects the coming year to be very profitable, and its dividend is expected to grow by 20.00% over the next year. After the next year, though, Portman's dividend is expected to grow at a constant rate of 4.00% per year. What is the expected dividend yield for Portman's stock today? 6.08% 7.60% 8.16% 7.31%
