Suppose a stock had an initial price of $65 per share, paid a dividend of $1.45 per share during the year, and had an ending share price of $58. a, compute the percentage total return. (a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) b. what was the dividend yield and the capital gains yield? (a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)
