    Errors Found in Study Materials P1.T2. Quantitative Methods (OLD thread)

    Hi @Elizabeth_Babalola Yes, indeed that is a typo. Apologies. Thank you for spotting this and identify the correction so helpfully. :) Tagged for correction

    YouTube T1-6 What is bootstrap historical simulation?

    HI @RajivBoolell Not stupid, thought provoking! It is true that the randomization is random discrete uniform variable; e.g., if there is a history of 21 daily returns, then the probability of selecting a specific historical day is 1/21. But this reflects our want to conduct a genuinely random...

    GARP Chapter 4 Books do not cover specific concepts

    @The Intrepid Thanks you. Maybe I should apologize, maybe the question is fine. I am sorry to be irritated: It was a Sunday (yesterday) and I was working all weekend on the last Tuckman T4 Tuckman (VRM 13) study note, and I resented interrupting that work to basically be a proxy for GARP...

    P2.T5. Jorion - VAR mapping - currency futures - Practice question number 19 on page 57

    Sure thing @Amns233 re updates, please see https://forum.bionicturtle.com/threads/2020-part-2-new-and-updated-published-materials.23057/ (Var mapping has been updated; we might have removed those EOC questions)

    GARP Chapter 4 Books do not cover specific concepts

    @jimmykaw You're kidding right :rolleyes:; we spent considerable time and effort on that chapter. Yes, Chapter 4 is updated. The LOs match, don't they? Here is the very first Learning Objective (LO) given by GARP at the start of the reading (and in the study guide/syllabus): "Compare different...

    Errors Found in Study Materials P1.T2. Quantitative Methods (OLD thread)

    Hi @Elizabeth_Babalola yes, thank you, I agree: not only more accurate, i think it's a necessary fix as the second term is currently wrong! Thank you,

    P2.T5. Jorion - VAR mapping - currency futures - Practice question number 19 on page 57

    Hi @Amns233 The initial hedge is a short position in the futures contract with F(0) = $1.4703. So initially, the exporter's exposure is a plan to receive 1.0 pounds in +3 months at the then-prevailing spot FX rate, hedged by the short position. When the hedge is lifted: The 1.0 million pounds...

    FRM Part 1 - key concepts

    Hi @DRoche I can help with that, when we update the formula sheet, but I want to first finish the outstanding study notes. There are always some customers who prioritize completeness of the materials, and I don't want to start the summary-type workflow revisions until we (me and our writer) have...

    Bond price vs Forward Rate

    Hi @nag_san thank you! The first sentence of the section (Maturity Effects) reads "What happens to the price of a bond if the term structure remains unchanged over a six-month period?" so that assumption is there, but I will tell you that I could not follow the rest of the new text, on its own...

    Bond price vs Forward Rate

    Hi @nag_san This is GARP's new re-write of Tuckman's Chapter 2 (Maturity and Price or Present Value) and is trying to explain the first part of this LO ("Assess the impact of maturity on the price of a bond and the returns generated by bonds"). Specifically, this refers to "Assess the impact of...

    Net Interest Margin question

    Hi @danielyyq and @chintanmatalia I agree that #2 is incorrect. This is a new 2020 reading, and I haven't entirely analyzed it, but i can see that it maybe lacks some consistent FRM-consisten vocabulary. Regardless, I think we can see how #2 must be a mistake. The author defines asset sensitive...

    Delta Gamma Neutral (Level) of a Short Straddle

    Hi @JorgeOrvananos glad @Sixcarbs could assist! I haven't look at the updated stuff. I'm in the same situation: I need to prioritize outstanding FRM customer support and content. I have still have considerable content updates in my stack (and unanswered customer questions) so it's not...

    Chapter 20 Swaps

    Thank you @Sixcarbs ! And @thanhtam92 I would add the following. Hull's setup question is copied below. As I often say, we want to assume all inputs in per annum term and we want to express outputs in per annum terms. Probably the most common discrete frequency (aka, periodicity) is semi-annual...

    End of Chapter Exercise for FRM Part 2 textbooks

    HI Yao (@lincoln40113 ) Regarding Part 1, I agree that GARP's new EOC questions apply to the LOs, but on the other hand, they are not exam-level practice questions. For the most part, they are too brief and easy. Fine for a first pass. But I would have preferred more rigorous questions that are...

    P1.Ch16 Hull 4.22

    Hi @thanhtam92 You don't necessarily need to translate between compound frequencies. Hull's problem 4.22 can be (easily) solved for the answer he seeks ($86.80) but you can't use the TVM worksheet (N, I/Y, PV, PMT, and PV) because they presume discrete periods. I was just responding to your...

    VaR for Equally likely outcomes

    Hi @nag_san Yes, it's because the lower bound of the (given) uniform distribution is -20.0, and VaR is the quantile associated with a (cumulative) probability such that we need to "start from the bottom" to include the entire left tail. In the uniform distribution, this exercise is essentially...

    Delta Gamma Neutral (Level) of a Short Straddle

    @JorgeOrvananos you are totally welcome, but we don't want to "force" you to buy (signup) for the FRM course unless you are sitting for the FRM exam. Our course is FRM exam prep. I am grateful that some folks occasionally ask for consulting work but i am not geared up to do consulting projects...

    Delta Gamma Neutral (Level) of a Short Straddle

    Hi @JorgeOrvananos I took a quick look (5 min), but I can't formulate the question properly (so I can't find a solution). It is interesting to ask, at which strike price is a straddle delta neutral? That occurs when call %delta is 0.5 because then put %delta will be -0.5, so that at some strike...

    sorry @jimmykaw that we don't have ePub but i just wanted to mention that you can annotate PDFs, I do it all the time, I use https://www.foxitsoftware.com/

    P1.Ch16 Hull 4.22

    Hi @thanhtam92 Your prices assume annual compound frequency, so to use your approach we'd want to translate the 11.0% (with CC) into exp(11%)-1 = 11.628% per annum with annual compound frequency. Note that we can confirm: n = 5, i = 11.628%, PMT = 8, FV = 100 and → CPT 86.01. Then, if we use a...
