7. Which of the following is false? a. Point C is the rninimum vari4ped iortfolio. ,/ b. Along the curve from.9to E, it is possible to have a combination of all three assets and Z. \ fti". .rsifraaiion between Large Cap Stocks and Small Cap Stocks is the reason point C is \*, sqpdrior to point B. \ Based on this gaph, your portfoiio should never be composed of 100% Treasury bonds\ AII of the above are true. 8. Which of the following is/are false about the EF (efficient frontier)? *- a. All the points on the efficient frontier are effrcient, that is each point provides the highest X return and the lowest risk. .< b. To calculate the EF requires data on the returns and risks of each asset and correlation coefficients (or covariances) between each pair of assets. -{
