Portfolio construction calculation individual, required, active, really

noel

according to the LOS of Reading 69, we're only required to know the steps of Treynor-Black model, but the EOS questions are really computationally intensive.

Do we need to compute every step till the end on exam day? I'm comfortable with the formula to calculate weighting of individual securities in the active portfolio and information ratio, but i just couldn't make it till the end.

Any thoughts on the requirements? Thanks!!
