Missing Question

                                     3 Doors, Inc.     Down Co.

Expected return, E (R)         16%                 11%

Standard deviation, s          49                   34.5

What is the standard deviation if the correlation is +1? 0? -1? (Round your answer to 2 decimal places. Omit the "%" sign in your response.)

Portfolio Variance = wA^2*σA^2 + wB^2*σB^2 + 2*wA*WB* σA* σB* ρAB

For correlation = 1

Portfolio Variance = 0.6^2*0.49^2 + 0.4^2*0.345^2 + 2*0.4*0.6*0.49*0.345*1

Portfolio Variance = 0.1866

Portfolio Standard deviation =

Portfolio Standard deviation = 0.4320

Portfolio Standard deviation = 43.2%

For correlation = 0

Portfolio Variance = 0.6^2*0.49^2 + 0.4^2*0.345^2  + 2*0.4*0.6*0.49*0.345*0

Portfolio Variance = 0.10548

Portfolio Standard deviation =

Portfolio Standard deviation = 0.3248

Portfolio Standard deviation = 32.48%

For correlation = -1

Portfolio Variance = 0.6^2*0.492 + 0.4^2*0.345^2 + 2*0.4*0.6*0.49*0.345*(-1)

Portfolio Variance = 0.0243

Portfolio Standard deviation =

Portfolio Standard deviation = 0.156

Portfolio Standard deviation = 15.6%
