    Backtesting VAR

    Question 4 - #30110In using a log-likelihood ratio to backtest a VAR model, the reason to measure the conditional rather than theunconditional coverage of the model is to consider the:A) number of assets in the portfolio tested.

    B) size of the portfolio.C) timing of exceptions.D) the influence of the positions of individual traders.Your answer: B was incorrect. The correct answer was C) timing of exceptions.The unconditional coverage test statistic allows for potential time variation ofthe data. A bunching of exceptionsmay indicate that market correlations or trading positions have changed.This question tested from Topic Area 1, Topic 5, AIM 5

    Within the Basel penalty zones, which of the following multipliers would most likely apply to a yellow zone with

    five to nine exceptions?A) 3.65.B) 4.00.C) 3.35.D) 3.00.Your answer: B was incorrect. The correct answer was A) 3.65.The yellow zone applies for five to nine exceptions with multiplier ranges from3.40 to 3.85. The green zoneapplies for zero to four exceptions with a multiplier of 3.00. The red zone applies for ten or more exceptions witha multiplier of 4.00.This question tested from Topic Area 1, Topic 5, AIM 6

    The Basel market risk charges require VAR to be computed over a horizon of:A) two calendar weeks or ten trading days.B) at least one year.C) at least three months.2 of 4 12/Mar/2014 10:59 AMD) one month or 21 trading days.Your answer: B was incorrect. The correct answer was A) two calendar weeks or ten trading days.The Basel Accord requires VAR to be calculated over a 2-week period or 10 trading days.

    Question 10 - #26972

    Comparison analyses on backtesting methods indicate that the most powerful verification test of VAR is the:A) unconditional parametric test statistic.B) conditional non-parametric test statistic.C) Basel committee test statistic.D) Kuiper test statistic.Your answer: B was incorrect. The correct answer was D) Kuiper test statistic.The Kupier test statistic has been shown to be the most powerful verification test.This question tested from Topic Area 1, Topic 5, AIM 3

    Question 1 - #126332Strip interest only CMOs are bonds that only pay the interest portion of mortgages. Assuming the CMO is tradedat par value, the duration is ____________ and the convexity is ____________.A) Positive; negative.B) Negative; negative.

    C) Positive; positive.D) Negative; positive.Your answer: B was correct!One of the biggest drawbacks to mortgage cash flows is the negative convexity. As interest rates decline the risein present value is offset by the prepayments. As interest rates increase, the decline in present value iscompounded by the extension of the mortgages.

    Question 2 - #124987In the past, if mortgage rates fell by more than 2%, refinancing activity wouldincrease dramatically. That effect is

    best described as the:A) lock-in effect.B) burnout effect.C) refinance effect.D) media effect.Your answer: B was incorrect. The correct answer was D) media effect.Large declines in rates will likely gain the attention of the media.Lock-in effect refers to borrowers who may wish to avoid the costs of a new mortgage which likely consists of ahigher mortgage rate.Burnout effect can be described as follows: consider a mortgage pool that was formed when rates were 8%,then interest rates dropped to 5%, rose to 8%, and then dropped again to 5%. Man

    y homeowners will haverefinanced when interest rates dipped the first time. On the second occurrence of 5% interest rates, mostowners in the pool who were able to refinance would have already done so.There is no such thing as a refinance effect per se.This question tested from Topic Area 1, Topic 17, AIM 3

    Question 9 - #124988Which of the following statements regarding principal-only (PO) and interest-only (IO) strips is (are) CORRECT?The IO price is positively related to mortgage rates at I. low current rates.II. The IO exhibits some negative convexity at low rates.III. PO strips are sold at a moderate discount to par.IV. PO prices increase when interest rates fall.A) I and II.B) II and III.C) I and IV.D) III and IV.Your answer: B was incorrect. The correct answer was C) I and IV.The PO (not IO) exhibits some negative convexity at low rates.PO strips are sold at a considerable (not moderate) discount to par.This question tested from Topic Area 1, Topic 17, AIM 8

    Question 10 - #9421Which of the following best describes a stripped mortgage-backed security (MBS)?A stripped MBS is a security:

    3/25

    A) that provides no interest payments.B) that provides no principal payments.C) whose distribution of principal and interest has been altered from a pro ratadistribution to an unequaldistribution.D) whose distribution of principal and interest has been altered from an unequaldistribution to a pro rata

    distribution.Your answer: B was incorrect. The correct answer was C) whose distribution of principal and interest has beenaltered from a pro rata distribution to an unequal distribution.With a passthrough security, interest and principal payments generated by the underlying mortgage pool areallocated to the bondholders on a pro rata basis. This means that each passthrough certificate holder receivesthe same amount of interest and the same amount of principal. Stripped mortgage-backed securities differ in thatprincipal and interest are not allocated on a pro rata basis.

    Question 14 - #9463Which of the following most accurately describes the term "securitizing a mortgage"?A) Selling an entire mortgage to another investor.B) Selling shares of one mortgage to other investors.C) Including a mortgage in a pool of mortgages that is used as collateral for amortgage passthroughsecurity.D) Offsetting the mortgage payments by an investment that generates exactly thesame cash flows.Your answer: B was incorrect. The correct answer was C) Including a mortgage ina pool of mortgages that is

    used as collateral for a mortgage passthrough security.A mortgage passthrough security represents a claim against a pool of mortgages.Any number of mortgages maybe used to form the pool, and any mortgage included in the pool is referred to as a securitized mortgage.Passthrough securities may be traded in the secondary market, and, as such theyeffectively convert illiquidmortgages into liquid securities. This process is called securitization.This question tested from Topic Area 1, Topic 17, AIM 5

    Question 16 - #126320The following are reasons that a prepayment model will not accurately predict future mortgage prepayments.Which of these will have the most significant effect on the convexity of mortgage pass-throughs?A) Seasoning.B) Refinancing burnout.C) Seasonality.D) Refinancing incentive.Your answer: B was incorrect. The correct answer was D) Refinancing incentive.The economic incentive to refinance as interest rates fall is the most powerfulfactor affecting the prepayment ofmortgage obligations.This question tested from Topic Area 1, Topic 17, AIM 3

    Question 17 - #30166Which of the following have greater price volatility than the pass-through from

    which they are derived?A) Principal only strips.B) Interest only strips.C) Neither interest only strips nor principal only strips.D) Interest only strips and principal only strips.Your answer: B was incorrect. The correct answer was D) Interest only strips andprincipal only strips.

    Both IOs and POs exhibit greater price volatility than the pass-throughs from which they are derived. This occursbecause IO and PO returns are negatively correlated.This question tested from Topic Area 1, Topic 17, AIM 8

    Question 18 - #30117Which of the following variables affect mortgage prepayment rates?I. Earthquakes.II. Season of the year.III. Volatility of mortgage rates.IV. Original rate on the mortgage.

    A) I and IV only.B) II and IV only.C) II only.D) I, II, III, and IV.Your answer: B was incorrect. The correct answer was D) I, II, III, and IV.The season of the year, volatility of mortgage rates, natural disasters such asearthquakes, and mortgage loancharacteristics such as the original rate on a mortgage are all factors that mayaffect mortgage prepaymentrates.This question tested from Topic Area 1, Topic 17, AIM 3

    Question 20 - #125677A CMO contains 4 tranches with the following characteristics:Tranche OAS (bps) Option cost(bps) Z-spread (bps)1 64 27 912 65 20 853 78 8 864 58 36 94Which of these tranches appears to be cheap?A) Tranche 3.B) Tranche 4.C) Tranche 2.D) Tranche 1.Your answer: B was incorrect. The correct answer was A) Tranche 3.A large option cost indicates a wider risk adjusted spread and a higher relativeprice. In general, the higher OASand the lowest option cost is most attractive. Tranche 3 has the lowest option cost and the highest OAS.This question tested from Topic Area 1, Topic 17, AIM 6

    Question 22 - #126326Which of the following products may be expected to provide the best hedge against impairment of mortgageservicing rights?

    A) 10-year Treasury note.B) Inverse floating rate collateralized mortgage obligation (CMO).C) Floor contract on the 10-year constant maturity Treasury (CMT) rate.

    D) Program amortization class (PAC) bond.Your answer: B was incorrect. The correct answer was D) Program amortization class (PAC) bond.The mortgage servicing rights associated with CMOs are assets that have cash flows that are uncertain becauseof mortgage prepayment risk. PAC bonds are CMO structures that are designed to minimize CMO prepayment

    risk.This question tested from Topic Area 1, Topic 17, AIM 8

    Question 26 - #126331A trader is bearish on the U.S. bond market (he thinks prices will fall in the short-term). Which mortgagederivative position will usually yield a profit if the trader's assumption is accurate?A) IO (interest only).B) PO (principal only).C) Inverse floater.

    D) None of these.Your answer: B was incorrect. The correct answer was A) IO (interest only).A trader who is bearish on the U.S. bond market believes that interest rates will rise. Of the three securitieslisted, only the IO would increase in value in such a scenario.This question tested from Topic Area 1, Topic 17, AIM 8

    Question 28 - #9424Which of the following best describes how accrual bonds distribute prepayment risk among tranches to createproducts that provide better asset and liability matching for institutional investors? Accrual bonds:

    A) do not allow prepayment for certain types of mortgages.B) accrue the interest for one tranche and redistribute it to the other tranches.C) have several different tranches to which accrued interest is directed sequentially.D) have a fixed principal repayment schedule that must be satisfied as long as the support tranches exist.Your answer: B was correct!For many sequential-pay CMO structures, the last tranche to be paid principal also does not receive currentinterest until the other tranches have been paid off. This tranche is called theZ-tranche or accrual tranche, andthe securities that represent a claim against its cash flows are called Z-bondsor accrual bonds. The interest thatwould ordinarily be paid to the accrual tranche is applied against the outstanding principal of the other tranches, insequence. The diverted interest from the accrual tranche accrues. That is, it isadded to the outstanding principalbalance of the Z-tranche.This question tested from Topic Area 1, Topic 17, AIM 8

    C) III and IV only.D) II only.Your answer: B was incorrect. The correct answer was D) II only.Local valuation methods measure portfolio risk by valuing the assets at one point in time, then makingadjustments to relevant risk factors that are expected to cause changes in the overall portfolio value. The deltanormal

    valuation method is an example of a local valuation method.This question tested from Topic Area 1, Topic 1, AIM 2

    Question 31 - #124969Which of the following statements regarding value at risk (VAR) and expected shortfall (ES) is least accurate?A) The calculation of lognormal VAR and normal VAR will be similar when dealingwith long-time periods.B) The ES provides an estimate of the tail loss by averaging the VARs for increasing confidence levels inthe tail.

    C) As the number of VAR observations increases, the ES will increase.D) The calculated VAR amount is always reported as a negative value.Your answer: D was incorrect. The correct answer was A) The calculation of lognormal VAR and normal VAR willbe similar when dealing with long-time periods.The calculation of lognormal VAR and normal VAR will be similar when dealing with short time periods. VAR isalways negative, but is typically reported as a positive value since the negative amount is implied.

    The weekly volatility is approximately equal to 2.08 percent a week ( ). The 5 percent VAR for thestock price is equivalent to a one standard deviation move, or 1.65 for the normal curve. The 5 percent VAR ofthe underlying stock is 0 2.08%(1.65)= 3.432%. A one percent change in the stockprice results in a 11.92percent change in the call option value, therefore, the delta = 0.1192/0.01 = 11

    .92. For small moves, delta can beused to estimate the change in the derivative given the VAR for the underlying asset as follows: VARCall =?VARStock =11.92(3.432%) = 0.409 or 40.9%.

    Question 5 - #134155Which of the following statements accurately describe filtered historical simulation? Filtered historical simulation:A) is the most comprehensive, and hence most complicated, of the parametric estimators.B) is not flexible enough to capture conditional volatility and volatility clustering.C) is only reasonable for small portfolios, and empirical evidence does not support its predictive ability.D) combines the historical simulation model with conditional volatility models.Your answer: B was incorrect. The correct answer was D) combines the historicalsimulation model withconditional volatility models.The filtered historical simulation is the most comprehensive, and hence most complicated, of the non-parametricestimators. The process combines the historical simulation model with conditional volatility models (like GARCHor asymmetric GARCH). Thus, the method contains both the attractions of the traditional historical simulationapproach with the sophistication of models that incorporate changing volatility.In simplified terms, the model isflexible enough to capture conditional volatility and volatility clustering as well as a surprise factor that could have

    an asymmetric effect on volatility. From a computational standpoint, this methodis very reasonable even for largeportfolios, and empirical evidence supports its predictive ability.

The correct answer was A) Documentation provided by borrower.Recent trends indicate that supplying documentation is becoming a less viable tool for mortgage lenders.

    Borrowers may not be denied credit in the event of no or little documentation, however, the mortgage rateassigned will reflect the riskiness of the loan.This question tested from Topic Area 1, Topic 18, AIM 1

    Question 3 - #143160In supervising an analysts research report on mortgages, you review a number of his statements.I. Longer mortgage terms result in slower build up of equity.II. Contiguous interest-only hybrid ARMs are generally less risky than noncontiguous interest-only ARMs.III. A front ratio of 33% would likely result in the classification of the loan as prime.

    Which of the analysts statements is/are correct?A) I only.B) I and II.C) II and III.D) I, II, and III.Your answer: B was incorrect. The correct answer was A) I only.Statement I is correct. Shorter mortgage terms are used by borrowers who want topay down their mortgagesfaster and build up their equity faster.Statement II is incorrect. Noncontiguous interest-only hybrid ARMs are meant toavoid the sudden increase inpayments usually associated with the simultaneous resetting and recasting of ARMs for contiguous interest-onlyhybrid ARMs.Statement III is incorrect. Loans that are classified as prime have a front ratio of 28% or less and a back ratio of36% or less.This question tested from Topic Area 1, Topic 18, AIM 1

    13/25

    C) I and III only.D) I, II, and III.Your answer: B was incorrect. The correct answer was A) I only.Prepayment consideration is the risk that the securities will be paid off early.There is no limited obligation forMBSs. Thus, only general business risk contributes to credit risk.This question tested from Topic Area 1, Topic 18, AIM 3

    Question 5 - #126319Which of the following statements describes the typical price behavior of a lowpremium mortgage pass-throughsecurity?A) It is similar to a U.S. Treasury bond.B) When interest rates fall, its price increase would lag that of a comparable duration U.S. Treasury.C) It is similar to a plain vanilla corporate bond.D) When interest rates fall, its price increase would exceed that of a comparable duration U.S. Treasury.Your answer: B was correct!

    Mortgage pass-through securities, unlike Treasuries or plain vanilla corporate bonds, have an embedded optionallowing borrowers to repay the loan at any time. When rates fall, the effectiveduration of these securitiesdecreases because borrowers will refinance mortgages at lower rates (putting theloans back to the investors);but when interest rates increase, borrowers will hold on to mortgages longer than they otherwise would, resultingin an increase in the effective duration of the loans. This is reflected in theprice/yield relationship as negativeconvexity.This question tested from Topic Area 1, Topic 18, AIM 3

Another five years passed and the interest rateincreased to 6% for the remainder of the term.Based on the information provided, which of the following amounts represents thetotal increase in monthlymortgage payments up to the first point the mortgage is recast?A) $958.B) $109.C) $417.D) $1,791.2 of 3 12/Mar/2014 11:10 AMYour answer: B was incorrect. The correct answer was A) $958.At the outset, the mortgage payments are interest-only, which results in a monthly payment of $833 ($250,000 x4% / 12). When the loan is reset (but not recast) five years later at a new rateof 5%, the monthly payment isstill interest-only but increases to $1,042 ($250,000 x 5% / 12). After the interest-only period is over at year 10,the mortgage is recast from interest-only to amortizing for the remaining 20-year term. The interest rate is 6%

    for the remainder of the term so the monthly payment increases to $1,791 (blended interest and principal).payment = 250,000 [(0.06 / 12) (1 + 0.06 / 12)^(20 12)] / [(1 + 0.06 / 12)^(20 1

    2) - 1] = 250,000 (0.01655 / 2.31) = $1,791.Therefore, the total increase in mortgage payment is $958 ($1,791 when the mortgage is recast year 10 versus$833 at the outset when the mortgage payments are interest-only).This question tested from Topic Area 1, Topic 18, AIM 2

    Question 3 - #70837Which of the following statements is (are) FALSE concerning extreme value distributions?

    Using block maxima, local maxima may not resemble extreme I. observations.II. Small tails reduce the variance of the tail index estimator in cluster analysis.III. The two classes of EVT models are block maxima and generalized extreme value distribution.A) II and III only.B) I and II only.C) I and III only.D) I, II, and III.Your answer: B was incorrect. The correct answer was A) II and III only.Small tails decrease the number of extreme observations, which will increase thevariance of the tail index(Statement II is false). Block maxima and peaks-over-threshold are the two class

    es of EVT distributions(Statement III is false).
