Mike Brandreth, an analyst who specializes in the electronics industry, is preparing a research report on Dynamic Communication. A colleague suggests to Brandreth that he may be able to determine Dynamics implied dividend growth rate from Dynamics current common stock price, using the Gordon growth model. Brandreth believes that the appropriate required rate of return for Dynamics equity is 8%. a. Assume that the firms current stock price of $58.49 equals intrinsic value. What sustained rate of dividend growth as of December 2013 is implied by this value? Use the constant-growth dividend discount model (i.e., the Gordon growth model). b. The management of Dynamic has indicated to Brandreth and other analysts that the companys current dividend policy will be continued. Is the use of the Gordon growth model to value Dynamics common stock appropriate or inappropriate? Justify your response based on the assumptions of the Gordon growth model.
