Elise just sold stock and realized a 4.1% capital gains yield and a 19% dividend yield for a 4-month holding period. What was her annualized rate of return (EAR)? What would be the return (EAR) if the holding period was 3 years and 9 months? Would your answer change if the holding period was 4 years? Over the past four years, a stock produced returns of 13, 6, -5, and 18 percent, respectively. What is the standard deviation of these returns? What would be the standard deviation of these returns if they were exactly twice the return shown for each year? If the return in the third year was +5% instead of -5%, would the risk of the stock measured by standard deviation increase or decrease
