●知识点:VaR的计算●
Normal VaR:
Lognormal VaR:
常考点:
1. 95%的VaR使用的关键值是1.65,99%的VaR使用的关键值是2.33。
2. VaR不满足次可加性,不是一致风险度量。
例题:
The annual mean and volatility of a portfolio are 10% and 40%, respectively. The current value of the portfolio is GBP 100,000. How does the 1-year 99% VaR that is calculated using a normal distribution assumption (normal VaR) compare with the 1-year 99% VaR that is calculated using the lognormal distribution assumption (lognormal VaR)?
A. Lognormal VaR is greater than normal VaR by GBP 13,040
B. Lognormal VaR is greater than normal VaR by GBP 26,718
C. Lognormal VaR is less than normal VaR by GBP 13,040
D. Lognormal VaR is less than normal VaR by GBP 26,5718
【正确答案】D
【答案解析】Normal VaR = - 0.1 + 2.33*0.4| = 0.8320;
Lognormal VaR = 1 – exp[0.1 – 2.33*0.4] = 0.5648;
Hence, with a portfolio of GBP 100,000 this translates to GBP 26,718.
