First of all, thank you for your lectures! Great material and help.
In the first part of the lecture “The impact of financing” around minute 12:30, you’ve been explaining the alternative solution of example 1 from the notes (chapter 12). You have mentioned that instead of using M&M equation we could use the Beta formula. However, there is no market return which I could use to calculate the market premium and at the end get the Beta. Is there any way around this issue?
You can only do it that way using algebra and letting the market return be X. As you work through the equations you will find that X ends up disappearing 🙂
However I really would not spend time doing it – it takes longer and there is more chance of making mistakes.
