Jensen's alpha is calculated as the actual return of the portfolio minus the expected return based on the Capital Asset Pricing Model (CAPM). The expected return is calculated as the risk-free rate plus the portfolio's beta times the market risk premium (market return minus risk-free rate). Here, the expected return is 3.27% + 1.31 * (10.84% - 3.27%) = 12.19%. The actual return is 14.76%, so Jensen's alpha is 14.76% - 12.19% = 2.57%. However, it seems there was a miscalculation in the options provided, and the closest correct calculation should be 1.57%.
