Spielberg builds a portfolio by investing in two stocks only: Microsoft (MSFT) and Huawei (SHE). According to the CAPM, the expected risk premium (i.e., the expected return minus the risk-free rate) of MSFT is 12.3% and the expected risk premium of SHE is 5.24%. The beta of MSFT is equal to 1.13. If Spielberg puts 63% of his money in MSFT stock and 37% in SHE stock, what is the approximate beta of his portfolio?
