Week in Financial Education (May 17, 2021)

Welcome to another Week in Financial Education! This week saw some great questions and fascinating insights. I will just highlight the instructive example of a flawed solution in the 2021 practice paper (as usual, the impetus is candidates’ justifiable confusion). This one is tricky because the correct answer is coincident with two implicit assumptions, but the approach will break under other conditions! One thing we’ve always cared about here (at Bionic Turtle) is mastery of the fundamentals. We don’t just want you to pass the exam. We want you to take away a robust toolkit. Part of that toolkit is fluency in the fundamental building blocks of finance, including its vocabulary. What exactly is meant by an “interest rate factor” and what are the possible instances of such a factor? The question (below) that we analyzed refers to bond yield, spread, and the implied hazard rate. Yield and hazard rates do have specific definitions, but spread requires clarification. (As another example, the question ultimately asks for “risk-neutral” cumulative default probability; what step in the solution does this risk-neutral assumption enable?). I hope you appreciate that we support your aspirations as a Professional by seeking to assist in the clarifications that constitute a robust and coherent toolbox.
