The theory suggests that the cost of equity is based on the stock’s volatility and level of risk compared to the general market. While beta can offer useful information when evaluating a stock, it does have some limitations. Beta can determine a security’s short-term risk and analyze volatility. However, beta is calculated using historical data points and is less meaningful for investors looking to predict a stock’s future movements for long-term investments. A stock’s volatility can change significantly over time, depending on a company’s growth stage and other factors. His next assignment is valuation of Bolan Electric Arts (BEA), a company engaged in production of electric vehicles.

It suggests the level of risk that an investor takes on in buying the stock. Stock 3 has a net cash position (negative net debt), so when it is converted, the asset beta is actually higher than the equity beta. This also makes sense because the value of cash never changes, so the volatility in the stock (equity beta) is actually lowered by the effect of the net cash position. The equity beta is usually what people refer to when they just say beta.

Equity is the remaining value of an asset or investment after considering or paying any debt owed; the term is also used to refer to capital used for funding or a brand’s value. The share price of a company can be found by searching the ticker or company name on the exchange that the stock is being traded on, or by simply using a credible search engine. Companies usually announce dividends far in advance of the distribution. The information can be found in company filings (annual and quarterly reports or through press releases).

Moreover, many Excel spreadsheets have already been set up as online beta calculators. You can download one and enter the information for the stock and benchmark you use. However, a Beta of 50% means there could be a one-in-two chance of losing your investment.

• Read on to learn more about using beta calculations to identify risk and volatility.
• The cost of equity is often compared to the cost of debt when making capital structure decisions.
• Equity beta is usually higher than asset beta, as considering leverage means the risk beta captures is higher.
• Beta can provide some risk information, but it is not an effective measure of risk.

Performing Beta Calculation in Excel: A Step-by-Step Guide

Often referred to as the “equity beta”, a levered beta is the beta of a firm inclusive of the effects of the capital structure. The logic behind the equation is that the company’s obligation to pay dividends is the cost of producing its shareholders. It represents the return that the market can expect to receive from the equity investment in a business.

Top 3 Formula to Calculate Beta

Equity is important because it represents the value of an investor’s stake in a company, represented by the proportion of its shares. Owning stock in a company gives shareholders the potential for capital gains and dividends. Owning equity will also give shareholders the right to vote on corporate actions and elections for the board of directors.

• Income investors seek shares with a low Beta because they are theoretically steady and reliable.
• The choice depends on the desired level of granularity and the availability of data.

How CAPM works

Stock Rover, our review-winning stock research and analysis screener, makes calculating Beta easy. Investors often use beta as one factor in determining whether a stock is suitable for their portfolio. A lower beta may indicate a more stable investment, while a higher beta could mean taking on more risk. The more you deviate and loosen the ranges the bigger an extreme you risk getting when building your risk profile. To be safe your ranges should mimic the high, low, and average betas from the previous years ranging from 1 to 10 years. As we stated earlier, performing the beta calculation by hand can be arduous, plus it opens you up to errors and miscalculations.

Let’s take an example to better understand the beta equation calculation in a better manner. Consequently, Beta is just one of several market analysis tools you should use. Understanding that Beta only provides a small piece of the big stock picture will help you avoid becoming too dependent. A big advantage of downloading a spreadsheet that calculates Beta is that some sheets use two formulas to determine Beta.

Open up the Excel file and keep the date column and the adjusted closing prices (feel free to delete the other columns). Then in a third column, calculate the daily stock returns by taking the percentage change of the day-to-day stock prices. Next, change the time period to five years back (5Y), click apply, then hit download. This will give you 5 years of historical stock price data in a CSV file that you can open in Excel.

Another popular formula for calculating the Beta is:

Computing the debt beta allows you to correctly derive the unlevered beta. Hence, you can use beta to determine the systemic risk of a security, analyze its volatility, and compute the cost of equity under the CAPM. It is primarily used in the CAPM (Capital Asset Pricing Model), which calculates the expected rate of return for an asset or investment. You can extract the implied debt beta from the CAPM formula by equating the formula to the cost of debt, or you can estimate the debt beta based on the credit rating of the company and its industry. Working with an adviser may come with potential downsides, such as payment of fees (which will reduce returns).

If the information cannot be located, an assumption can be made (using historical information to dictate whether the next year’s dividend will be similar). A security with a high R-squared value indicates a relevant benchmark. A gold exchange-traded fund (ETF), such as the SPDR Gold Shares (GLD), is tied to the performance of gold bullion. Consequently, a gold ETF would have a low beta and R-squared relationship with the S&P 500. The market that the stock trades in, such as the S&P 500, always has a beta of 1.0.

Practical Applications: Applying Beta in Investment Decisions

For example, car sales or lithium prices affect Tesla’s bottom line. Or the effect of news stories about an accounting scandal or lousy sales at a company. Analysts often equity beta formula use the mathematical symbol β to represent the Beta in calculations. Beta can give you an estimate of a stock’s risk and some idea of market volatility.

Can we trust this calculation?

For example, a company with a beta of 1.5 has returns that are 150% as volatile as the market it’s being compared to. Investors and businesses calculate companies’ costs of equity to determine whether investments (in either stock or capital projects) carry risks that are commensurate with the projected returns. The cost of equity, along with cost of debt, determines a company’s overall cost of capital, while cost of equity is an important input in stock valuation models. Cost of equity helps to put both risk and value into context, enabling investors to make better-informed decisions. The beta (denoted as “Ba” in the CAPM formula) is a measure of a stock’s risk (volatility of returns) reflected by measuring the fluctuation of its price changes relative to the overall market.
