CAPM is a way to figure out how much money you might expect to make from an investment based on how risky it is.
Imagine you're playing a game where you can choose between two different treasure chests. One chest has shiny gold coins, and the other has maybe some gold coins or maybe just rocks, you never know what's inside. The riskier chest (the one with rocks) might give you more money if you win, but it could also leave you empty-handed.
CAPM is like a smart friend who helps you decide which treasure chest to pick by looking at how much risk there is and how much people usually earn from similar games. It uses something called the market return, that’s like the average amount of gold coins everyone gets from all their chests, and compares it to how risky your particular chest is.
So, if you know how much the whole market usually earns and how risky your investment is, CAPM can help you guess how much money you might get back. It's a bit like using a map to plan your path through the treasure hunt.
Examples
- Imagine you're choosing between two investments: one is a safe bond, and the other is a risky stock. CAPM helps you figure out which might give you better returns based on risk.
- If your favorite company's stock has a beta of 1.2, that means it's more volatile than the overall market, CAPM can show you what return you should expect from it.
- Think of CAPM like a recipe for calculating how much money you might make from an investment based on how risky it is.
