Quant 2: Describing Returns

Part two of the Quantitative Methods arc for Level I candidates: once you have a set of returns, how do you describe them honestly? No formula walls, just the intuition, small round numbers, and the calculator doing the heavy lifting. In a two host format, one host explains the material while the other plays a fictional exam candidate.The episode asks three questions about any set of returns. Where is the middle: arithmetic, geometric and harmonic means and how they rank, the median and outliers, trimmed and winsorized means, and why a fund's time-weighted return and an investor's money-weighted return can tell different stories. How spread out are they: range, mean absolute deviation, sample versus population variance, standard deviation, the coefficient of variation and target downside deviation, plus why volatility lowers the rate at which money compounds. And what shape are they: skewness, named by its tail, and kurtosis, or fat tails.Each section names its trap, and three exam-style practice questions at the end show how the traps turn into wrong answer choices.All people, funds and numbers in the examples are fictional, and the examples are simplified for exam practice. Comparisons between invented funds are a test-taking skill, not a recommendation or evaluation of any investment.Free practice exam, 90 questions (free account): tottenprep.comTotten Prep is independent educational content for exam preparation only.
