Capital Asset Pricing Model (CAPM):

Part of the huge capital market assumption that attempts to quantify investment risk. Under CAPM, systematic risk is calculated by a statistical factor labeled beta, which is the mathematical term of the relationship among the return on personality privacy and the return on the market as a whole. The market return is common by a market index, such as the Dow Jones Industrial Average or the Standard  & Poor's 500 compound Stock Price directory. In other words, beta measures the volatility of a given privacy beside market averages. The CAPM states that the value of a financial privacy depends only on the statistical relationship among the privacy and the cost of all privacies that trade in the financial markets. Investors that purchase risky assets get an expected return that is advanced than an investment in risk-free assets.
