What is the expected return and standard deviation of each of the three portfolios?
Provided Above = Weight of Market Index * Standard Deviation of Market Index
What is the beta of each of the three portfolios?
Provided Above Beta of Market Index is always equal to 1. Beta = Weight of market index * Beta of Market Index
What is the risk premium on the index portfolio?
Risk Premium = Market Return - Risk Free Rate = 10% - 3% = 7%
What criterion would you use to choose between the three candidates?
I would use sharpe ratio to calculate reward to risk ration to choose best stock
BONUS: What are the expected return, standard deviation, and beta of your portfolio if you have $100,000 of your own to invest and you borrow another $100,000 at the risk free rate so you can buy $200,000 of the market index?
Expected Return = Calculated above = 17%
standard deviation = Calculated above = 48%
Beta = calculated above = 2
