    Course Study Notes and Vital Source

    Thank you @gsarm1987 that is such helpful insight (I didn't even think about the font size!) Hi @LBela4498 Welcome! Thanks for the question/feedback. We don't often get the criticism that the notes are too dense. (I will punt the VS question because I don't have an immediate answer on VS)...

    Gregory, Ch3 (Ch9 GARP): Netting

    HI @enjofaes I think that's a reference to Gregory's example (later) in "6.4.4. Netting Impact on Other Creditor". See diagram below. The base case (on the left) is without netting where B's position with respect to ... Party A (Derivatives creditors) is Asset = 140 and Liabilities = 200, and...

    HI @MAli9983 On YouTube, I pinned my comment that explains those calculations: ... then, of course, once we've solved for 38.26 we can see that $63.763 - $38.26 = $25.51. I hope that's helpful!

    Course Errors Found in 2021/2022 Study Materials P2.T9. Investment Management

    Hi @Shau_2207 Re last paragraph of page 51, apologies but I can see we made a mistake and it should match what Ang says (emphasis mine): "The beta anomaly is not that stocks with high betas have low returns—they don’t. Stocks with high betas have high volatilities. This causes the Sharpe...

    Futures contract sizes

    HI @GEBEN9829 Lately the exam has been giving the contract sizes in any futures contract question; and I continue to believe that a good question provides the assumption so you don't need to memorize. However, among my original list over a decade ago (yikes!) Just to be "safe," I'd still...

    Spreadsheets

    HI @PMcAt5366 Yes, the intention is to include all spreadsheets, but to be candid, I'm a behind on updating them. It is something I am currently working on: updating the XLS to include all of our best work. Will keep you posted ... Thanks!

    Explain Correlation-weighted HS example

    HI @frogs It is straight-up (literally) from Dowd's example in his Chapter 4. Matrix A is defined by Choleski's decomposition; in Dowd's Chapter 8 he more clearly defines it so if the historical correlation, rho = 0.30, then you can below (my super quick XLS below) how A*A^T = correlation...

    GARP.FRM.PQ.P2 GARP Mock Exam 2022 Part II - Q 29 Probability

    HI @yukoc100 GARP is correct. If the question were instead "What is the conditional probability of default during the second year?" then the answer would be 10.03% / (1 - 0.12*1) = 11.3%. But the questions asks for the joint (aka, unconditional) probability of default during the 2nd year, such...

    Chapter 5 Sample moments

    HI @JGURR5668 Here are the two sheets (but keep in mind that the simulated panel has random numbers so generates a new set each time) https://www.dropbox.com/s/udmnbogicmejhzx/3rd_4th-moments.xlsx?dl=0

    Chapter 5 Sample moments

    HI @JGURR5668 Not errors. For skew, notice I matched to Excel's skew per the "Excel F()" below; the sample skew shouldn't be smaller than the population skew (0.198 <? 0.201). So the adjustment used is 19.8*100/[(100 - 1)*(100-2)]/1.0^3 = 0.2040x and this sample skew is greater than the...

    Chapter 4: Multivariate Variables (p. 16)

    Hi @viswa27 sorry, it's not a question I can help with because I don't agree with the language. On the one hand, it's too simple, but on the other hand, it's too sloppy (i.e., X, actual Y, conditional given X < 1,300 ... WTH). It's just not a good question and, thankfully, nothing like you'd see...

    P2.T6.608. Credit Derivatives (1TD CDS, TRS, CLN) Crouhy

    Hi @Jackk90 Mainway is hedging the loan (to which it has credit risk exposure) as a TRS payer: if the loans drops in value (aka, it's underlying exposure) that the TRS is a hedge because the TRS counterparty pays Mainway; similarly, if the Loan increases in MTM value, then Mainway would pay with...

    << to be detailed in next major revision >>

    Hi @ASche3191 There is a ton of discussion on this if you search the forum, but very briefly consider a portfolio with 100 credits (loans) and each has PD of 2.0%. If there is zero default correlation, the probability of (eg) at least one default is 1 - 98%^2 = 86.7%; i.e., a low default...
