Question: Suppose there are two stocks 1 and 2. The expected return of stock 1 is 0.6, and the expected return of stock 2 is 0.5.

Suppose there are two stocks 1 and 2. The expected return of stock 1 is 0.6, and the expected return of stock 2 is 0.5. The standard deviation of stock 1 is 0.6, and the standard deviation of stock 2 is 0.3. The covariance between stock 1 and stock 2 is 0.05.

Suppose there are two portfolios, P and Q. Their portfolio weights are in the table below:

Portfolio i wi,1 wi,2
P 0.2 0.8
Q -0.5 1.5

Here wi,1wi,1 represents the portfolio weight in Stock 1, and wi,2wi,2 represents the portfolio weight in Stock 2.

What is the covariance between Portfolio P and Portfolio Q returns? Round your final answer to 3 decimal places.
