Now that you have read about the CAPM, would you ever use it to make personal investment decisions? How can an individual investor use or think about CAPM?

Consider the following:

What is the main message of the CAPM? It evolves from the notion that investors in general aren’t stupid: They diversify their investment funds into a well-diversified portfolio. More specifically—the main message of the CAPM is that the rate of return one should expect to earn on a particular investment is only related to the systematic risk of the security, not to its total risk. When you purchase a stock (because you like it or because you got a ‘tip’), you’ll be exposed to the total risk of this stock, but the market theory implies that you’ll only be compensated for a small proportion of that risk. Hence, if you do like risk you should invest in a well-diversified risky portfolio with many securities having a high beta, rather in an individual stock. Now go back to the initial question and present your thoughts…
