Final answer:
The student's query involves the creation of an arbitrage portfolio to capitalize on the expected excess return difference between the fund DQXQ and the market return, using the concept of beta and adjusting portfolio weights to achieve this.
Step-by-step explanation:
The student is asking about creating an arbitrage portfolio based on the expected excess return of a particular fund (DQXQ) compared to the expected excess return of the market, and the beta value of the fund. Arbitrage involves leveraging the difference in prices or returns between two or more markets in order to create a risk-free profit. Given the information that the student expects a 15.5% excess return on DQXQ and a 13.3% excess return on the market with a beta of 1.3 for DQXQ, they are considering how to structure their portfolio weights (Wp, Wmkt, Wrf, alpha) to exploit mispricing. The student is provided with various portfolio weight options that involve adjusting the proportions of the portfolio invested in DQXQ, the market index, and the risk-free asset, including borrowing or lending a percentage of the portfolio value.
