Welcome to the latest week in financial education (WIFE)! As the May exams have started, we experienced another busy week. We are grateful for some fabulous contributions by members (see links below). At this time of year, many candidates are naturally focused on practice question revision, not just from our database but also other sources like GARP's Practice Exams. This always elicits informative feedback on the issue of question quality. We are constantly reminded that Imprecise or poorly worded questions prove to be debatable (or at least confusing) when they are stress tested. In the worst case, a flawed question can actually reinforce a mental mistake. GARP's question about a repo transaction (link below) is a fine example. This is a question that GARP had already revised twice in 2016-17 due to imprecisions but even their updated version could be improved. My strong belief is that a good question should not make the candidate struggle to interpret any input assumption (e.g., is the given bond price a quote price or an invoice price?); given limited time, it is hard enough to perform the calculation required by the question.
I hope you like this week's new practice questions. The new correlations (Chapter 12) set should give you good coverage on some useful techniques: The Jarque-Bera test of normality, the power law for heavy-tail distributions, and a low-difficulty quiz asking you to find rank (Spearman's and Kendall's tau) correlations. The latter (rank correlations) is also a concept in Topic 5 (Part 2, Market Risk) where we had the pleasure of contributing an edit to FRM author Gunter Meissner's book (see https://trtl.bz/2rseaBT for details). If you happen to be a visual thinker like me, here is how I handle concordant/discordant pairs, it's simple: concordant pairs lie in the first (I) or third (III) quadrant https://trtl.bz/3y76ans. About the portfolio construction question set, I calibrated them as approachable; as we've often observed, the weakness of this reading assignment (Grinold Chapter 14) is the lack of scaffolding: the material presumes you've read prior chapters in the book. Have a good study week!
