You require a rate of 8% on General Motors' stock. General Motors is not in a constant growth phase. Azero prowth individend model is probably a better estimate of the value of the common stock Do not buy this stock. It is worth a negative amount Use the constant growth in dividend method to find the value of the stock General Motors appears not to be earning money for its stockholders Question 2 1 pts In the constant growth dividend model for valuing stock and finding expected return on stock, the assumption is that Dividends pald on the stock are zero.
