Kurtosis (for the @CFA Level 1 exam) explores the properties of mesokurtic, leptokurtic and platykurtic distributions in the context of investment returns.
Thanks a lot sir for you informative and precise videos covering all the concepts for CFA L1. It's really helping us a lot. I just want to say that if possible then can you also make a video upon correlation? I tried to understand it from C-Book but I felt it was difficult.
So far, I have 14 videos in the Quantitative Methods playlist :) ru-vid.com/group/PLzsMtRJ44d8wjM4ajDGdNm2h8qUIPjPR0 This one is going to grow :) and there's also the Time Value of Money playlist, which is part of Quants: ru-vid.com/group/PLzsMtRJ44d8xXi87bE0HaQ3gXKmlbhDQ5
The first question has no correct answer. Kurtosis measures neither peakedness nor concentration toward the mean. You can have perfectly flat distributions with high kurtosis, and you can have infinitely peaked distributions with low kurtosis. Kurtosis measures tails only, which is relevant for finance because it concerns the occasional wild returns. CFA needs to revise their material.
