# What is “Capital Asset Pricing Model” ?

In finance, Capital Asset Pricing Model has been commonly used as a term that determines the price of risky securities and evaluates the bond between the risk and expected return. An equation is being used by investors to specifically determine the time value and risk of money that corresponds to their compensation.

On the other hand, an investor is more likely to spend money hoping that the initial investment will gain profits. The Capital Asset Pricing Model (CAPM) will now be responsible in determining these profits.

Using the formula, the return from the portfolio can easily be determined which is equal to the rate of the risk-free security.

The result from using the formula will be added on the risk premium. An investment must not be made if the result is relatively low. Additionally, the formula will likely allow you to enter the number into the equation. Expect that you would receive an answer from your investment question.

Implementing and understanding CAPM is quite a challenge to some but effortless to others. Financial advisors and consultants would help to establish your goals and determine how much to invest on your funds. They are the most trusted persons that can explain the trend in research and industry where the best option for investment may be. Protect your investments and financial securities with “Capital Asset Pricing Model” (CAPM).

How Capital Asset Pricing Model (CAPM) Functions
Now, you may ask yourself how capital asset pricing model functions. The “capital asset pricing model” basically functions in an understanding that investors will need additional compensation as they invest on a risky adventure. It may also take into consideration the money’s time value.

A CAPM calculator has a formula that mainly uses information in order for the necessary return can be calculated. These three pieces of information are as follows: expected market return, risk-free rate and beta of investment.

The “beta of a stock”, however, is considered as the deviation that is compared to the market. The “return of investment” or (ROI) is now the result of multiplying beta times the difference between the risk-free rate and expected market return, plus the risk free rate.

Mostly, all financial planners make use of capital asset pricing model (CAPM) to decide if the “risk of a stock” can be added on the client’s portfolio. The CAPM is sometimes used to judge if changes are necessarily made in the portfolio. However, there are important things you must consider when applying for the CAPM model.

The exact definition of the model must be fully understood to determine not only the capital, but the stock as well. The CAPM formula is basically used to understand how a diversified asset reduces risk. Apart from it, one of the main advantages of CAPM is its formula as the basis for financial decision.

The Birth of Capital Asset Pricing Model (CAPM)
Additionally, CAPM has been introduced by William Sharpe, a financial economist. He merely introduced it in his book entitled “Portfolio Theory and Capital Markets” in the year 1970.

The idea from his model starts with an individual investment that relatively contains two kinds of risk:

• Systematic Risk- Examples of systematic risk includes recessions, interest rates and wars.
• Unsystematic Risk- This market risk is relatively known as “specific risk” as it targets individual stock. It can be expanded away wherein the investor increases his stocks in his portfolio. In a more technical term, it merely represents the stock’s return component not correlated with the moves in general market.

Additionally, Sharpe has found out that the individual stock or portfolio of stock and its return must be equal to the cost of capital. The CAPM’s standard formula remains the same, which merely describes the relationship between expected return and risk.

What Capital Asset Pricing Model (CAPM) Can Do For You
Since you already know its history, you must know that the model clearly presents a simple theory which gives a simple result. The theory briefly explains that an investor could earn more once he invests in one stock than a riskier stock. Unsurprisingly, CAMP has obviously dominated the theory on modern finance. However, does CAPM really work?

Actually, it has been said that the model’s work isn’t yet clear because of beta. When Kenneth French and Eugene Fama carefully looked at the “New York Stock Exchange” share returns, they found out that betas have differences when observed in a long period of time.

However, they did not fully explain the difference in performance between stocks. In fact, the linear relationship between the individual stock and beta has broken down on a certain period of time. With this finding, it has strongly suggested that CAPM could be wrong.

Although there are doubts concerning the CAPM’s validity, still, the model is widely used in the community where investment is widespread.
