Questions 1:
An investor wants to maximize the possibility of earning at least 5% on her investments each year.
Using Roy’s safety-first criterion, the most appropriate choice for the investor is portfolio:
A 、3.
B、 2.
C、 1.
Questions 2:
Compared with historical simulation, Monte Carlo simulation is most appropriate when:
A 、probability distributions are unavailable.
B 、“what if” analysis is required.
C 、analytical methods are required.
【analysis】
Portfolio 2 has the highest SFRatio, so it is the most appropriate choice.
C is incorrect because 0.35 is less than 0.64.
A is incorrect because 0.425 is less than 0.64.
B is correct. Monte Carlo simulation lends itself to “what if” analysis and requires the user to provide a probability distribution or distributions. It can be a complement to analytical methods.
A is incorrect. Monte Carlo simulation requires probability distribution
C is incorrect. Monte Carlo simulation can be a complement to analytical methods. Analytical methods provide precise results, whereas Monte Carlo simulation does not.
成功=时间+方法，自制力是这个等式的保障。世上无天才，高手都是来自刻苦的练习。而人们经常只看到“牛人”闪耀的成绩，其成绩背后无比寂寞的勤奋。小编相信，每天都在勤奋练习，即使是一点点的进步，大家一定可以成为人人称赞的“牛人”。
