I watched few of your lectures. You were teaching about alpha and portfolio theory. I didnt find such things in kaplan study text. i still have to watch the few more videos on portfolio theory. is it examined or out-dated lectures? just confirming.
As I have explained in the lecture notes, that although the examiner has said that calculations on portfolio theory will no longer be examined you are expected to be aware of the idea. So I have left the lectures because it is easier to understand the idea by at least seeing the basic calculations rather than just having it all in words 🙂
