Problem 7-12 Nonconstant Growth Stock Valuation Assume that the average rm in your company's industry is expected to grow at a constant rate of 6% and that its dividend yield is 8%. Your company is about as risky as the average rm in the industry, but it has just successfully completed some R&D work that leads you to expect that its earnings and dividends will grow at a rate of 50% [D1 = Do(1 + g) = Do(1.50)] this year and 25% the following year, after which growth should return to the 6% industry average. If the last dividend paid (Do) was $1.5, what is the value per share of your nn's stock? Round your answer to the nearest cent. Do not round your intermediate computations. $ Problem 7-11 Declining Growth Stock Valuation Brushy Mountain Mining Company's coal reserves are being depleted, so is sales are falling.
