Rafael is an analyst at a wealth management firm. One of his clients holds a $5,000 portfolio that consists of four stocks. The investment allocation in the portfolio along with the contribution of risk from each stock is given in the following table:

Stock	Investment Allocation	Beta	Standard Deviation
Atteric Inc. (AI)	35%	0.900	38.00%
Arthur Trust Inc.(AT)	20%	1.600	42.00%
Lobster Supply Corp. (LSC)	15%	1.300	45.00%
Transfer Fuels Co. (TF)	30%	0.300	49.00%

Rafael calculated the portfolios beta as 0.920 and the portfolios expected return as 12.90%.

Rafael thinks it will be a good idea to reallocate the funds in his clients portfolio. He recommends replacing Atteric Inc.s shares with the same amount in additional shares of Transfer Fuels Co. The risk-free rate is 6%, and the market risk premium is 7.50%.

According to Rafaels recommendation, assuming that the market is in equilibrium, how much will the portfolios required return change?

1.81 percentage points

1.22 percentage points

1.95 percentage points

1.57 percentage points

Analysts estimates on expected returns from equity investments are based on several factors. These estimations also often include subjective and judgmental factors, because different analysts interpret data in different ways.

Suppose, based on the earnings consensus of stock analysts, Rafael expects a return of 9.83% from the portfolio with the new weights. Does he think that the revised portfolio, based on the changes he recommended, is undervalued, overvalued, or fairly valued?

Overvalued

Fairly valued

Undervalued

Suppose instead of replacing Atteric Inc.s stock with Transfer Fuels Co.s stock, Rafael considers replacing Atteric Inc.s stock with the equal dollar allocation to shares of Company Xs stock that has a higher beta than Atteric Inc. If everything else remains constant, the portfolios beta would increase or decrease?
