计算假设借款利率为9%。假设,标准普尔500指数已经预期回报的13%,标准偏差的25%,射频(Rf)= 5%,考虑以下冒险的基金(E(r)= 11%,标准偏差= 15%),以及无风险资产 1。什么是范围的风险规避程度,客户端将不向别人借钱,也不借钱给,这是为y = 1 ? 2。什么是最费,一位客户目前是贷款(y < 1)会愿意花去你投资的资金呢?一个客户借贷(y > 1)吗? 计算题,不是翻译,要的是答案 Suppose that the borrowing rate is 9%. Assume that the S&P 500 index has an expected return of 13% and standard deviation of 25%, that Rf= 5%,Consider the following a risky fund(E(r) = 11%, standard deviation = 15%), and a risk free asset 1. What is the range of risk aversion for which a client will neither borrow nor lend, that is, for which y=1? 2. What is the largest percentage fee that a client who currently is lending (y<1) will be willing to pay to invest in your fund? What about a client who is borrowing (y>1)?
