Now, the formula for the expected return of a portfolio whose components are assets A and B is:

wA*rA + wB*rB

where wA and wB are the weights of assets A and B in the portfolio; and rA and rB are the expected returns from assets A and B. Let's say that the government bonds are asset A and the market ...
