Runkle, CFA2011 Modular Level I, Vol. 1, p. 463Study Session 2-8-kCalculate and interpret covariance and correlation.Diversification benefit requires correlations less than positive one.When we do not reject a false null hypothesis we have a Type II error.

2、An analyst does research about hypothesis testing and conducts a significancetest to determine if the relationship between two variables is real or the result ofchance.His null hypothesis is that the population correlation coefficient is equalto zero and his alternative hypothesis is that the population correlation coefficientis different from zero.He develops the following information:The analyst conducts a:【单选题】

B.two-tailed test and can reject his null hypothesis.

C.two-tailed test and can not reject his null hypothesis.

Runkle, CFA2013 Modular Level I, Vol. 1, Reading 9, Section 3.3, Example 9Study Session 3-9-nDefine shortfall risk, calculate the safety-first ratio, and select an optimal portfolio using Roy’s safety-first criterion.B is correct. The portfolio with the highest SFRatio is preferred. The SFRatio is calculated by subtracting the target return from the expected return and dividing by the standard deviation.Portfolio 1= 0.35Portfolio 2= 0.64Portfolio 3 (22 – 5)/40 = 0.43B has the highest SFRatio, so it is the most appropriate choice.

5、An analyst gathers the following information about the performance of a portfolio ($ millions):The portfolio’s annual time-weighted rate of return is closest to:【单选题】

A.8%.

B.27%.

C.32%.

正确答案:C

答案解析:The time-weighted rate of return is calculated by computing the quarterly holding period returns and linking those returns into an annual return as follows:The time-weighted return (TWR) is found as follows:2014 CFA Level I“Discounted Cash Flow Applications,” by Richard A.
