The expected return on Big Time Toys is 12% and its standard deviation is 20.6%. The expected return on Chemical Industries is 11% and its standard deviation is 25.9%. a. Suppose the correlation coefficient for the two stocks' returns is 0.23. What are the expected return and standard deviation of a portfolio with 38% invested in Big Time Toys and the rest in Chemical Industries? (Round your answers to 2 decimal places.) Portfolio's expected return % Portfolio's standard deviation b. If the correlation coefficient is 0.73, recalculate the portfolio expected return and standard deviation, assuming the portfolio weights are unchanged. (Round your answers to 2 decimal places.) Portfolio's expected return % Portfolio's standard deviation % c. Why is there a slight difference between the results, when the correlation coefficient was 0.23 and when it was 0.73? v (Click to select) The higher the correlation is between the two variables, the higher the potential is for diversification. The higher the correlation is between the two variables, the less the potential is for diversification
