Hello,
Full exam taken in Geneva.
I hope I pass, but “I should not sell the bear skin before killing as we say in french”.
It is all the most true as I had to guess several questions because I would have lost too much time on it.
The key risk parameter for this exam is TIME management.
As the questions are still fresh in my mind and in order, for future participants,
to gauge the exam difficulty, here are the questions I remember.
I think that examples are the best way to know how tough are the questions.
Sorry for the spelling error, I am rushing as I was rushing during the exam…
1. Gold forward arbitrage with continuous yield (2%) and Rf (4%).
The future price was lower that the computed one.
What should be done to “gain” the arbitrage?
2. One BII market risk capital charge computation, be careful daily var was 95%.
So we had to convert to 99%.
I think this was coming to around 267000 or close to that after scaling the 95% Var to 99% and to 20 days
3. Currency forward arbitrage (Rf and time provided)
4. Volatility smile descriptive question (currencies and equities)
5. Maximum likelihood (you should take the log and tell what to maximize/minimize)
I think here Lambda should be maximum. Second choice goes
6. No Poisson question
7. Easy Binomial: What is the prob that a student has less than 8 answers right
if he answers randomly a two possibility answer test with 20 question.
You did not have to compute but just to say how to compute.
This was option 3 as the second option was sounding right at the first sight but it was a uniform distribution
8. Several questions that required put/call parity (including S*exp(-y*t))
There was one question on European PUT and American CALL…...I htink we can’t apply put/call parity. So I said the same.
9. Several questions on option combinations (butterfly spread)
There was this box spread arbitrage. Is it option 3?
10. One greek question
I think in the money options lose more than any other option.
11. No TRS question
12. Several CDS questions (impact of correlations)
One of the CDS answers, I was getting +14 to the banker
13. Lots of var questions
14. Not too many questions on BII compared to var questions.
15. One Tier1 and Tier2 BII computation
This was option C in my paper. Don’t know if they jumble the answers as well.
16. Model risk question
17. One UBS (easy) question
I think they were easily earning over LIBOR by investing AAA.
18. Why stress testing var
19. Indirect question on backtesting var
20. One easy swap computation (2 years remaining, Libor against 8%)
I got it as +14 to the bank.
21. One easy question on interest rate: Which one is higher?
They gave yearly, monthly, quarterly and continuous numerical values.
The answer was continuous.
Yeah. Even I got the same answer.
22. Several questions on linear regression:
Compute R^2. Beta has bad t-stat and the strategy is to be market neutral -> what can be concluded?
One was coefficient of determination. Given Beta was .977. So the R^2 turns out to be .913
23. A few questions on IR, Sharpe and Treynor ratio.
I was confused by one because they were calling the tracking error, the systemic volatility or something like that.
24. One portfolio credit risk model question
25 One very easy question on matrix transition: Which statement is incorrect?
There was a line with BBB down grade proba > 80%...
26. No rating question
27. Difference between CDO and MBS (I answered the tranching)
Don’t we have tranching in both? I think we do….but not sure.
28 CDS question on price of first to default versus second to default.
This, the FTD always is costlier or equally costly to STD second to default
29. No moral hazard question
30. One SPE usage question.
40. No inverse floating question
41. A few modified duration question. (DeltaV = -D* * V * deltaY)
There wasn’t a perfect answer .....I went for the closest one.
42. Which obligation has negative convexity:
good to see easy question and not time consuming.
43. An easy proba computation:
z-proba of not been between 1 and 1.5 or something like that.
The z table was provided for each test on the first page.
44. P(A|B) computation:
I had P(A and B) by using P(B|A) but I did not have the time to compute P(B)
because the text was long and I needed at least 5 minutes to recompute.
This is a typical question when I lost point because I had to avoid loosing time.
This was the one I was talking about. It came out to be 38.67%
45. One easy question kurtosis:
The normal has lowest proba of extreme value than 4, 8 kurtosis distributions.
Yeah. Even I went for it.
46. Several EVT questions: one was to compute it with extreme returns provided.
47. One var question:
20 worst returns provided but unsorted. Find the var, It was 1% of 80 Million as far as I remember.
Exactly. I got the same.
48. You decrease significance what happens to Type I and Type II probs.
TYPE II increases
49. One binomial tree call computation question that I failed.
I wasn’t getting answer for this. I got less than 1. So I went for the lowest answer which was 2.
50. One Monte Carlo simulation of GBM (mu was zero to be easier), sigma was provided
You had to compute S(n+2) given S(n) e(n) and e(n+1).
I also failed because I did not want to loose too much time on computations
and I made a mistake in the contribution.
There were two options like 97.79 and 99.79. We also had 99.69. So I thought it should be 99+ and should .79 => 99.79 
51. No Cholesky or interest rate model question.
52. One Ted behaviour (after Lehman episode) question.
But there were two possible good answers as far as I understood.
I answered that the it increases because there was a lack of liquidity
(for me the fact that all bankers we scared of lending was a liquidity funding problem).
This sounds very much logical but one of our collegues on this site has posted a link which says it peaked in Oct.
53. One or two linear hedging question (rho * sigma(S) / sigma(F))
54. Concerning study cases, a single question on MetallGesellshaft
THis was backwardation to Contango and not the otherway round
55. Two questions on basis risk.
Short hedge benefits from basis strengthening. The other one I think only that had same underlying and same T will not have Basis risk and all others had.
56. A liquidity VAR computation:
Normal distribution for return with mu and sigma, value of portfolio and spread value in dollar provided
I wasn’t getting answer for this.
57. One EWMA and one Garch (compute the long term vol for Garch)
This has nothing to do with the exam. But it remembers my wife’s boss explaining to me that Garch
has nothing to do with modeling heteroskedostaticity.
As he is responsible for Market Risk Management, I should have suggested him to take the Garp exam.
THere was another. THat has increasing R^2. Is it coz of multicollinearity?
58. An interesting question on style drift versus leverage increase for HF.
They were providing the fund returns and the benchmark returns.
You could see that one manager increases leverage (same signs for returns) and the other was doing style drift.
This was a good logical question. I answered the same way.
58. Tracking error:
3 graphs were given with benchmark and fund returns. Tell which one has lowest tracking error.
The one which had two graphs move parallelly was what I have chosen. It may not be correct.
59. Correlation:
3 graphs were provided. Which group of variables has the highest correlation?
60. An easy question on credit risk: Which operation adds CR: sell/buy options
selling a call option I guess
61. One Merton question (that I failed) close to the one provided in Garp2009:
Compute prob of default
I got DD as 3.6
61. Two EL and UL computations (PD, LGD, COM, sigma(PD), sigma(LGD) were provided)
62. Two questions on credit “modifiers” (Triggers, Netting, collateral, MTM)
63. No cat bound question
64. One Raroc computations (no taxes were involved and RC was provided)
I was getting it as 2.6 to achieve a min of 15% return
65. One BS call/put computation N(d1) and N(d2) were provided
66. One interest risk reduction question (buy a cap, sell a floor, ...)
I went for options i, ii and iii.
67. One or two questions on MVAR, CVAR questions:
Compute the global VAR if a fund is removed
Compute an MVAR
See you,
