By adjusting the weighting of the four assets within the portfolio, a beta of 1.2 could be conceivably achieved. To calculate the expected return of the portfolio, you divide the current value of the first asset by the total value of the portfolio, and multiply it by its expected return: Portfolio Expected Return = $800,000 divided by $1 million, times 5%.
