**The Capital Asset Pricing Model (CAPM)** is a statistical tool for valuing investments. It outlines the various factors that affect the cost of an equity. In this article, I’ll discuss Beta, Systemic risk, and the Cost of equity. I also discuss some of the fundamentals of the markets. I’ll conclude by recommending some books on the topic. After you finish this article, you’ll have a better understanding of **CAPM** and its various components.

## Beta

The beta of the * Capital Asset Pricing Model *is the rate of change in an individual security’s expected return relative to the market’s risk. In other words, investors use beta to adjust the equity risk premium, or premium for the equity risk of an individual security.

A beta of 2 would mean that the individual security was twice as risky as the market. In financial markets, the risk is synonymous with volatility. Using beta to compare risk and return in equity portfolios helps investors determine the correct equity risk premium.

The beta of a company’s stock is affected by the nature of its business, including its relationship with the macroeconomic environment.

Usually, cyclical firms have higher betas than noncyclical ones. Also, firms with higher debt tend to have higher betas than firms with less discretionary products. Beta also depends on the amount of financial leverage a company has. Debt increases a company’s fixed cost, which increases the exposure to market risk.

### Market fundamentals

**The CAPM** measures market-related risk. The beta for security represents the risk associated with the investment. A security with a high beta will be priced to generate a high expected return. Conversely, a security with a low beta will be priced to generate a low expected return.

While unsystematic risk can be minimized through diversification, it does not increase an investor’s expected return. Instead, financial markets focus on systematic risk and price securities to generate the expected return along the security market line.

**The CAPM** explains how investors’ expectations of returns for assets are related to the risk involved in acquiring those assets. The model shows that the expected return of an asset is equal to the risk-free rate plus a risk premium based on the beta of the security.

This model is also widely used in finance to help investors determine which assets to purchase. But it is not a fool-proof formula. For example, the **CAPM** has a few flaws. It cannot be relied upon to predict the future market. Nonetheless, it does provide a useful guideline in the pricing of stocks and bonds.

### Systemic risk

**The capital asset pricing model (CAPM)** describes the relationship between the systematic risk and the required return for an investment. In the model, no security would sell at a low price for a long period of time.

Instead, investors would bid up the price of securities to match the expected returns of other securities of the same risk. Once the price of the security reached its high point, investors would sell it off. This process would continue until the systematic risk justified the expected return.

Systematic risk is also referred to as volatility risk. The sensitivity of a security’s return to its market return is used to calculate its volatility. The sensitivity of a security’s return to its market returns is the opportunity cost associated with assuming systematic risk. As a result, investors seek to diversify against systemic risk by paying a premium. Assuming this risk, investors often demand higher prices.

### Cost of equity

There are many ways to calculate the cost of equity for a particular stock. The most popular method is called the * capital asset pricing model (CAPM)*. This model uses volatility in the stock market to predict how a stock’s price will perform over time.

The dividend capitalization model, on the other hand, uses a formula that only works for companies that pay consistent dividends. This formula uses stock prices that increase over time and the volatility of these stocks.

The cost of equity for a division can be calculated using **the capital asset pricing model** estimates of the cost of equity for similar independent companies. The betas for the companies should reflect the risk level of their industry, but refinements may be required to account for differences in financial leverage and other factors.

For example, if a company is acquiring a new company, the cost of equity should reflect the risks inherent in the target company’s discounted cash flows.

### Investing in equities

The CAPM is a financial model that takes into account a company’s risk relative to the overall risk of the market. It adjusts an equity risk premium when a particular stock is riskier or safer than the market. There are two main types of risk: systematic and non-diversifiable.

Systematic risk refers to uncontrollable market risks, such as interest rate fluctuations or political unrest. Systematic risk also includes uncontrollable risks, such as market failure, and non-systematic risks, such as natural disasters.

**The CAPM** relies on assumptions to determine the necessary return on equity investments. Generally, the model assumes that investors will make the same decisions as those who own the securities. This means that investors will typically prefer less risky securities in exchange for higher returns.

However, a few assumptions may change the outcome of a particular scenario. For example, if the government starts a war, the **CAPM** may not accurately predict the outcome.

#### Investor behaviors

The investor behavior in **The capital asset pricing model** is based on the assumption that investors behave as risk averse individuals who demand compensation for taking on a certain level of risk. Higher-risk security is priced in a way that maximizes expected return. This relationship is expressed in a simple equation: risk = expected return / risk-free rate. It is easy to see that the risk/return relationship is positively skewed toward higher returns.

When estimating risk and return, investors may choose to assume that market volatility and information blockage are both significant in explaining the behavior. In other words, the model based on investor behaviors may underestimate the risk of certain asset classes, and exaggerate the risk of under or over-performance.

For example, investors in a low-income bracket may choose to stay out of the market, and a high-income investor may be a good candidate to take advantage of the opportunity cost of investing in a lower-income neighborhood. We talked about the capital asset pricing model.
