I’m trying to get a better understanding of Active Risk, I’ve seen it being asked a couple of time in the mocks. It’s used to calculate the Information Ratio as Active Risk / Active Return
Can someone please explain the components of Active Risk?..i.e Active Factor Risk and Active Specific Risk. The book is rather confusing…
So Active Risk is basically the systematic risk (measured by the beta) - diversifiable risk. Active specific risk is non-systematic risk. Something that you cannot diversify away. This is also idiosyncratic risk.
IMO, active factor risk represents systematic risk which cannot be diversified away, but active specific risk repserants non-systematic risk (conntected with a given company) which can be diversified away.
I would assume active specific risk could be diversified away of the two, because its excessive exposure to one stock instead of an index. But I don’t know for sure.
I would highly recommend Elan’s PM video for this. The guy’s done a really good job on this. The only thing is it’s 4 hourslong (Basit Shajani) for the entire PM chapter and may not be worth yoru while at this stage.
I saw Elan’s videos for the first time this year. I’m definetly using that to study moving forward, as I learn much easier watching someone and following along. The few videos I used this year helped a lot – but they are too long to watch at this point.
I meant watching his videos and reading CFAI, not in place of. I use CFAI and then get videos to go over the material a second time after I finish reading everything.
