Not mentioned at all in Schweser - likely to come up in the exam - obviously its in the curriculum but id rather not have to learn all the formulas if its only an outside shot of coming up. Any speculative thoughts?
It came up L1 in June
it is in the CFAI books. the prep guys dont cover it
I remember Stalla brought it up, though in my year it was L2 material - since moved to L1. I think my L2 exam also had a question where it came up - though I don’t remember for sure.
