FRM二級(jí)市場(chǎng)風(fēng)險(xiǎn)測(cè)量與管理真題解析VaR
【題目1】
A trader was estimating the 1-day 90% VaR on a domestic commodity portfolio using the historical simulation approach (equally weighted) with a 30-day look back period. The 4 most extreme negative returns over the look back period were:
5 days later, the portfolio has experienced 2 extreme negative returns: -3.0%, -1.9%. What is the new updated VaR now?
A. 3.0%
B. 2.6%
C. 2.8%
D. 3.2%
答案:B
解析: 根據(jù)給出的新信息,我們可以得到收益新的升序排序:-3.2%、-3.0%、2.6%,對(duì)于30個(gè)觀察樣本來說, 1天的90% VaR是倒數(shù)第三收益(10%×30=3)的負(fù)數(shù), 即2.6%。
關(guān)聯(lián)考點(diǎn):VaR計(jì)算
易錯(cuò)點(diǎn)分析:
容易選擇C選項(xiàng),因?yàn)?2.8%對(duì)應(yīng)27天前,5天過去后,這個(gè)數(shù)據(jù)已經(jīng)從窗口期中滾動(dòng)出去了,所以不用再考慮。
【題目 2】
Which of the following statements comparing VaR with expected shortfall is true?
A. Expected shortfall is sub-additive while VaR is not.
B. Both VaR and expected shortfall measure the amount of capital an investor can expect to lose over a given time period and are, therefore, interchangeable as risk measures.
C. Both VaR and expected shortfall depend on the assumption of a normal distribution of returns.
D. VaR can vary according to the confidence level selected, but expected shortfall will not.
答案:A
關(guān)聯(lián)考點(diǎn):VaR與ES性質(zhì)對(duì)比
易錯(cuò)點(diǎn)分析:容易錯(cuò)選C,VaR與ES對(duì)分布并沒有嚴(yán)格的假設(shè)。
