in CFA terminology, shortfall risk is probability, the VaR statement and shortfall statement I’m sure were not the answer

It doesn’t matter for me. My doubt was between semivariance and VAR. thetank Wrote: ------------------------------------------------------- > bluelily Wrote: > -------------------------------------------------- > ----- > > It was the right definition in one way.

csk, I read the definition but I still stand by my understanding. Shortfall can be a value. For instance when you use Roy’s Safety First ratio, you can define shortfall as say 5%, then it can be also considered minimum acceptable return. However, when you talk about “shortfall risk”, like many of the IPS questions do, and when you define it as expected reurn - # * std, you have to assume some sort of distribution of returns, and in that case shortfall value is determined based on the probability associated with it (based on the area under the curve).

Is there a semi-variance question in the AM? @#%!#%#%&^%*^???

volkovv, i am not going to argue. Maybe you are right. I am just very tired of trying to decipher what CFAI tries to explain. I think CFAI should jump off their high mountain and realize that their test is a joke comparing to any decent post-graduate degree.

I thought I missed a whole question. I gotta stop reading all the posts. It drives me insane now. oskigo Wrote: ------------------------------------------------------- > bluelily Wrote: > -------------------------------------------------- > ----- > > Is there a semi-variance question in the AM? > > @#%!#%#%&^%*^??? > > > no but there was a question as to an alternative > to standard deviation or something of that > variety.

The semivariance was the right answer. Shortfall risk and VAR statements were correct. VAR does give you a probability of a DOLLAR amount loss but doesn’t give you the magnitude of the loss and Shortfall Risk is a probability of having a return lower than some target. Even with asymmetric returns, semivariance becomes extremely difficult to calculate.

^ I second the “high mountain” comment

I think I’m remembering this right: If it was the one with shortfall and four statements, the description of shortfall itself wasn’t even accurate.
