Ask the Tutor ACCA AFM

Modigliani and Miller vs. CAPM

DDaniel9y ago
Could you please give a hint on: when are we supposed to use CAPM vs MM when it comes the ACCA P4 exam? Is it that we use CAPM is we have a Beta in the question; otherwise it is MM? I am losing it! I feel most of you would laugh, but I know 2 more students that can't answer the question.

It is not a question of M&M as against CAPM. M&M deal with the affect of gearing. CAPM deals with the effect of business risk. There is a CAPM formula that allows us to measure the business risk when we know the full risk (including gearing) and vice versa - but that formula effectively comes from M&M. If you want to ask about specific questions then I will explain why they have done what they have done, but otherwise you really should watch my free lectures where I explain both M&M and CAPM (and the relationship) in detail. (And you should suggest the same think to the other 2 students you know :-) )

Thank you! We did watch... I guess we need to watch again or just be happy with only "13 exams":)

Do watch again, but also do ask if you have a problem on this in any specific past exam questions and I will explain. But again, it is never a choice between M&M and CAPM - they are looking at two different (albeit connected) aspects of risk.
