Question
Examining stochastic processes: Assume 3 risky assets X, Y, Z where the expected return of X is 7%, the expected return of Y is 4%
Examining stochastic processes:
Assume 3 risky assets X, Y, Z where the expected return of X is 7%, the expected return of Y is 4% and historical/ deterministic/ observed returns of Z is 0.02%.
We also know that the variance of X is 20%, the variance of Y is 5% and the correlation of X and Y is -0.2 . The person who holds these assets puts them in a portfolio and decides that X is 70% of the portfolio, Y is 25% of the portfolio and Z is 5% of the portfolio.
Question 1: If the person wants the standard deviation of the portfolio to remain at 10% then how much weight should they allocate to each asset ?
