What is the non-arbitrage principle?
Explain why might it be a good idea to invest in assets that covariates negatively?
Explain what the problem with the covariance as a measure of relation is and what is the measure that corrects this problem.
You have two assets with standard deviation of returns, 2% and 3%, respectively for assets 1 and 2. If you invest 30% in asset one and the covariance between them is 0.5, what is the standard deviation of this portfolio?
If the weights on your portfolio composed of three assets are 20%, 30% and 50% and the expected return on the same assets are 4%, 6% and 7.5%. what is the expected return on the portfolio?
Compute the correlation between assets A and B IF YOU KNOW THAT THE STANDARD DEVIATION OF B is 50% of the standard deviation of A and the covariance between the two assets is 0.5 times the variance of asset A.
You have three assets A,B and C. The expected returns on those assets are 5%, 8% and 12%. The standard deviations are 2%, 4% and 10%. Your decide to invest 20%,45% and 35% in assets A,B,C, respectively.

What is the expected return on the portfolio?
What is the variance on the portfolio if the covariance among all the assets are zero?
