YOU MUST INDICATE IN DETAIL THE MATHEMATICAL CALCULATIONS REQUIRED. Today, you buy four shares of XYZ stock costing $80 per share. One year from now, you purchase three more shares for $85 per share. Two years from now, you sell five shares for $82 per share. Three years from now, you sell the remaining two shares for $87 per share. The stock pays a $3 dividend per share at the end of each year of the next threq years. You are preparing to calculate the dollar-weighted average rate of return. A. Calculate the relevant cash flows that are required in order to compute the dollar-weighted average rate of return. B. Set up the relevant equation that must be solved in order to compute the dollar-weighted average rate of return. (Note: This problem does not require that you calculate the dollar-weighted average rate of return. That is, you are not required to solve the equation you set up for Part (B).)
