问题如下：
Calculate the expected total risk premium of the three securities and determine the investor’s probable course of action.
选项：
解释：
The average spread (over 1-year government bond) at issue is [0 + 1 + (1 + 0.75 + 0.55)] = 3.3%/3 = 1.1%.
As the 1.1% is less than 1.5%, the investor will not make the investment
解析：
1年期政府债券的平均利差为[0 + 1 +(1 + 0.75 + 0.55)]= 3.3%/3 = 1.1%。
由于1.1%低于1.5%，因此投资者不会进行投资。
题目要求计算三种资产的risk premium，为什么答案只算了portfolio的risk premium？
