Question 1 (1 point)

We have two very long wires, which are parallel to each other pointing to the right in front of us. The pair of wire is horizontal. The wire closest to us carries a charge per unit length of 1mC/m and the other the opposite charge. The two wires are 1m apart and both move together at 100m/s along the wire to the right. We are looking at what happens in the middle region of the two wires (not the end). For the question pick all the right answers (there can be more than one correct answer).

A stock is currently selling on the NYSE for $40 per share. Based on the last twelve months, this represents a P/E ratio of 12.5 and a dividend yield of 4.8%. After an analysis of all the relevant variables, you estimate that the dividends per share will grow at an annual compouind rate of 8% and that GMA will maintain the same payout ratio each year as the previous year. GMA stock is expected to sell at a 15 P/E ratio at he end of the third year. Your required rate of return is 12% per year. Based on a three-year investment horizon and assuming that all your estimates are correct, how much is the stock currently over or under priced?
