# What Is a Market Risk Premium?

## Introduction

A market risk premium is an allowance in the rate of return investors seek from investing in stocks over the rate of return from a risk-free asset, such as government bonds. It is a measure of the extra compensation investors demand to invest in assets with the added possibility of risk.

Generally, stocks are riskier than government bonds because stocks' market price fluctuates with the underlying company's success, whereas bonds offer more stability in price. To attract investors to stock investments, companies offer attractive returns in comparison to government bonds.

In this blog, we will examine the concept of a market risk premium, the role of a market risk premium in a company's investment decisions and the factors that determine the size of its premium.

## Definition of Market Risk Premium

A market risk premium is the additional return that an investor expects from investing in a risky market rather than in a risk-free asset. It is used to calculate the cost of equity, which is an important component of a company’s cost of capital. In order to understand the concept of a market risk premium, it is important to understand the difference between risk-free and risky investments.

### Definition of a Market Risk Premium

In financial markets, an investment is considered risk-free when there is no chance of losing the principal invested. For example, government bonds issued by the U.S. Treasury are generally considered to be risk-free investments as they are backed by the full faith and credit of the U.S. government. Conversely, investments in stocks, options, futures and other financial instruments are considered risky as there is no guarantee of the principal being returned. The difference between the return that an investor expects from investing in a risk-free asset, such as the U.S. Treasury bond, and the return from a risky asset is referred to as the market risk premium.

### Calculation of a Market Risk Premium

The market risk premium is generally calculated by subtracting the expected return from a risk-free investment from the expected return from a risky investment. This can be expressed mathematically as:

- MRP = ERR – RFR
- Where:
- MRP = Market Risk Premium
- ERR = Expected Return on Risky Asset
- RFR = Risk-Free Rate

It is important to note that the market risk premium is not a fixed value, but rather a measure of risk at a given time. As such, it can fluctuate depending on economic conditions, investor sentiment and other factors.

## Use of Market Risk Premium

The market risk premium can be useful in both accounting and investment decisions. It is an estimate of returns an investor should require to invest in a particular asset. The value of the premium, informed by past market trends, helps business owners and investors to make important investment decisions.

### Accounting Purposes

The market risk premium is helpful when making business decisions, as it can help inform the expected rate of return from a potential investment. This rate of return can be used to value investments or to identify the minimum return required to accept the investment. It is also a valuable indication of the risk taken by the investor in an uncertain market environment.

### Investment Decisions

The market risk premium can be used by investors to determine a reasonable expected return for a given level of risk. By analyzing the current and past risk premiums of an investment, investors can determine the expected return they can expect relative to the risk they take. Additionally, the risk premium can also be used to compare the relative returns of different investments, making it an important tool in the selection of investments.

Investors can also adjust the market risk premium to take into account any potential risks that may not be captured in the historic premium. By adjusting the premium to account for the specific risks associated with the expected return, investors can fine-tune their investment decisions for the current market conditions.

## Advantages and Disadvantages of Market Risk Premium

One of the fundamental questions for a financial analyst is whether to invest in a stock or to invest in a bond. Calculating the market risk premium is a key element when deciding which type of asset to invest. The market risk premium is the added expected return on a stock above the risk-free rate of return, which is used to determine the rate of return of a portfolio or stock.

### Advantages

The market risk premium, when used correctly, can provide investors a number of advantages:

- The market risk premium eliminates the guesswork when investing in the stock market. By calculating the expected market risk premium, investors know that they can expect a certain return on their investments, with the current market conditions.
- The market risk premium also helps to diversify an investor’s portfolio. By understanding the expected returns of different assets, investors can build a portfolio that best meets their goals, with the least risk.
- The market risk premium is an excellent tool for risk management. By understanding the expected risks of investing in a specific asset, investors can make better decisions about how much to invest and in what assets.

### Disadvantages

Although the market risk premium can be a useful tool for investors, there are some drawbacks that should be taken into consideration:

- Calculating the market risk premium can be difficult, as it relies on the correct formula and a thorough understanding of the current market conditions.
- The market risk premium is not a perfect tool, and it does not take into account short-term market movements, which can result in investments that do not perform as expected.
- The market risk premium assumes that all investments have the same risk profile. Therefore, investors must take into account the individual risks associated with each asset they are investing in.

## 5. Common Misconceptions about Market Risk Premium

The market risk premium is a foundational financial concept, but there are still many misconceptions and misunderstandings about it. It is important to be aware of these misunderstandings so as to not make incorrect decisions when calculating the cost of equity or other valuations.

### a. Misconceptions about cost of equity

The area where most misconceptions about the Market Risk Premium arise is in computing the cost of equity. Many assume that the risk premium should be calculated by taking the difference between the market yield and the risk free rate. This is not the case, as the risk premium should factor in not only the risk free rate but also the expected returns from other investment that an investor might engage in. A correct risk premium should factor in not only the risk free rate but also the expected returns from other investments that an investor might have engaged in. Without factoring in expected returns of other investments, the risk premium will likely be understated.

### b. Misconceptions about price of equity

Another misconception about market risk premium relates to the price of equity. Many assume that the risk premium should be included when calculating the price of equity. However, this is not the case; the price of equity should only take into account the expected return provided by the common stock investments, and not the additional risk required to attain that return. To correctly and accurately calculate the price of equity, you should use the expected return from your common stock investments and not the risk premium.

Understanding the role of market risk premium and accurately computing the cost of equity is essential to making the right financial decisions. While there are some common misconceptions, it is important to take the time to ensure you are factoring in all required elements in order to make an informed decision.

## Factors Influencing Market Risk Premium

The market risk premium is the difference between the expected return on a portfolio containing global stocks and the return from a risk-free rate. It is an important component in the calculator for CAPM and is used to determine the ideal portfolio distribution in relation to expected return. There are a few major factors which affect the market risk premium which need to be taken into account when making investment decisions.

### Risk-free rate

The risk-free rate is typically considered to be the return on a 3-month US treasury bond. This rate forms the basis of comparison when considering the expected return of a portfolio with risk. If the risk-free rate is trending higher, the premium associated with the portfolio containing risk must also increase to stay at a positive return.

### Beta

Beta quantifies a securities risk. A beta of less than one represents a security with lower volatility than the market, while a beta above one indicates that the security will be more volatile than the market. There is an inverse relationship between beta and the risk premium associated with that security. Portfolios constructed with securities with higher betas will have higher market risk premiums.

### Maturity period

The maturity period of a security has a direct impact on the risk premium associated with it. Generally, the longer the maturity period, the greater the risk premium. This is due to the higher uncertainty with respect to the security's value at maturity. As such, a higher risk premium is required to compensate the investor for the increased risk.

Overall, the market risk premium is something which must be taken into consideration when evaluating a portfolio of investments. These factors can be used to determine the optimal mix of securities and the expected return required to offset any risk. Each of the factors discussed should be seriously considered when making investment decisions.

## Conclusion

The market risk premium is an important concept to consider when evaluating investment options. It can help investors to determine the potential return of their investments, as well as assess the level of risk associated with those investments. By understanding the concept of the market risk premium, investors can make informed decisions about which investments to choose and how to manage their portfolios.
