a. calculate the expected returns of stock a and stock b
b. what are the stand-alone risk of stock a and stock b
c. calculate the coefficient of variation of stock a CVa and stock b CVb
d. Suppose the market is in equilibrium (That is, required returns equal expected returns). The required return from a market portfolio is 10% and risk-free rate is 2%. Calculate systemic risk of Stock A (βA) and Stock B (βB)
a. calculate the expected returns of stock a and stock b
A = 15%
B = 10%
b. what are the stand-alone risk of stock a and stock b
A = 24.19%
B = 10.49%
c. calculate the coefficient of variation of stock a CVa and stock b CVb
CVa = 161.25%
CVb = 104.88%
d. Suppose the market is in equilibrium (That is, required returns equal expected returns). The required return from a market portfolio is 10% and risk-free rate is 2%. Calculate systemic risk of Stock A (βA) and Stock B (βB)
Beta of Stock A = (Expected return - Risk Free rate) / (Market Rate - Risk Free Rate)
Beta of Stock A = (15% - 2%) / (8%)
Beta of Stock A = 1.625
Beta of Stock B = (Expected return - Risk Free rate) / (Market Rate - Risk Free Rate)
Beta of Stock B = (10% - 2%) / (8%)
Beta of Stock B = 1.0
Beta means systematic risk
