- CAPM is just a “model” or formula used to calculate COST OF EQUITY

- Cost of Equity is how much an investor “wants” to earn for investing in a company which is more risky than a safe bank deposit (or government bond), and (usually) more risky than investing in the general stock market with a bunch of stocks.

- It’s called a “cost” because that’s how much you should “fairly” pay your investors for investing in your risky company.

- In more complicated problems, you include the cost of equity as part of your WACC or Weighted Average Cost of Capital

- CAPM assumes that investing in many stocks is safer than investing in just one company’s stock: “don’t put all your eggs in one basket” sorta thing.. this is called “diversified” risk

- Rationale: An investor would “want” (or “expect”) more income (“return”) for investing in a highly risky company instead of the zero-risk bank/bond, and also instead of investing in a “medium-risk” general stock market. Therefore, cost of equity = “expected return”

You calculate Cost of Equity using the CAPM or Capital Asset Pricing Model Formula:

K_{e} = R_{f} + B (R_{m}-R_{f})

DON’T panic! It’s MUCH EASIER than it looks! See this formula step-by-step in action, watch it for free in the video above.

THANK YOU!!!

My professor is HORRIBLE and after hours and hours of listening to his lectures on CAPM and WACC I still didn’t get it. Then I found your videos and within one hour I completely understood both concepts! You saved my graduate school career!!!

@Elizabeth glad to hear you understand better and your grad school career is saved. Happy to be a part of it.

Thanks a million, outstanding video.

Hi Waddle, glad it helped

I don’t how you can make things so simple! Thanks a million!

@Hou glad you find it simple!
