Suppose a multifactor model has three factor risk premia: market = 6%, profitability = 3%, and investment = 2%. A stock has: 𝛽 𝑚 𝑎 𝑟 𝑘 𝑒 𝑡 = 1.1,                   𝛽 𝑝 𝑟 𝑜 𝑓 𝑖 𝑡 𝑎 𝑏 𝑖 𝑙 𝑖 𝑡 𝑦 = 0.5,                       𝛽 𝑖 𝑛 𝑣 𝑒 𝑠 𝑡 𝑚 𝑒 𝑛 𝑡  = -0.2, And the risk-free rate is 3%. What is the expected return? (Please answer in % and round to 2 decimal places. If the answer is 8.057%, then in the box, write 8.06)数值题
