The expected return of the new fund using the Capital Asset Pricing Model (CAPM) can be calculated with the formula:

$R_i = R_f + \beta_i * (R_m - R_f)$

Where:

• $R_i$ is the expected return on the fund.
• $R_f$ is the risk-free rate.
• $\beta_i$ is the beta of the fund, which measures the fund's volatility in relation to the market index.
• $R_m$ is the expected return on the market index.

Given:

• The risk-free rate $R_f$ is 3.0% per year.
• The expected annual return of the Shanghai Composite Stock Market Index (SHANGHAI), $R_m$, is 7.6%.
• The new fund has twice the volatility of the index, so its beta $\beta_i$ is calculated as: $\beta_i = \frac{\text{Volatility of the fund}}{\text{Volatility of the index}} = \frac{2 \times \text{Volatility of the index}}{\text{Volatility of the index}} = 2$

Plugging the values into the CAPM formula: $R_i = 0.03 + 2.0 \times (0.076 - 0.03)$ $R_i = 0.03 + 2.0 \times 0.046$ $R_i = 0.03 + 0.092$ $R_i = 0.122$ $R_i = 12.2\%$

Therefore, the expected return of the fund is 12.2%, which corresponds to option A.
