Final answer:
The expected return of the portfolio is approximately 19.02%.
Step-by-step explanation:
To calculate the expected return of a portfolio, we need to consider the weights and expected returns of each asset in the portfolio. In this case, we have shares of Shark and Rhino.
First, calculate the total investment in Shark: 610 shares x $21.00 = $12,810.
Then, calculate the total investment in Rhino: 575 shares x $17.00 = $9,775.
Next, calculate the weighted average beta: (610/1185) x 1.97 + (575/1185) x 1.35 = 1.651.
Finally, calculate the expected return: Risk-free rate + (Beta x (Expected return on market - Risk-free rate))
= 4.00% + (1.651 x (13.00% - 4.00%))
= 4.00% + 15.0159%
= 19.0159%.
Therefore, the expected return of the portfolio is approximately 19.02%.
