Multiply the beta value by the difference between the market rate of return and the risk-free rate. For this example, we'll use a beta value of 1.5. Using 2 percent for the risk-free rate and 8 percent for the market rate of return, this works out to 8 - 2, or 6 percent.
How do you calculate the beta of a stock?
To calculate the Beta of a stock or portfolio, divide the covariance of the excess asset returns and excess market returns by the variance of the excess market returns over the risk-free rate of return: One of the most popular uses of Beta is to estimate the cost of equity (Re) in valuation models.
Do lower beta stocks with less volatility carry less risk?
Lower beta stocks with less volatility do not carry as much risk, but generally provide less opportunity for a higher return. The beta coefficient is calculated by dividing the covariance of the stock return versus the market return by the variance of the market.
How risky is a stock with a beta of 1?
If you make your beta calculations and find out the stock you're analyzing has a beta of 1, it won't be any more or less risky than the index you used as a benchmark. The market goes up 2%, your stock goes up 2%; the market goes down 8%, your stock goes down 8%.
What is the beta of a stock that moves more than market?
A stock that swings more than the market over time has a beta greater than 1.0. If a stock moves less than the market, the stock's beta is less than 1.0. High-beta stocks tend to be riskier but provide the potential for higher returns; low-beta stocks pose less risk but typically yield lower returns.
How do you calculate the beta of a stock?
Beta could be calculated by first dividing the security's standard deviation of returns by the benchmark's standard deviation of returns. The resulting value is multiplied by the correlation of the security's returns and the benchmark's returns.
What is the beta of a risk-free stock?
A zero-beta portfolio is a portfolio constructed to have zero systematic risk, or in other words, a beta of zero. A zero-beta portfolio would have the same expected return as the risk-free rate.

Is market risk and beta same?
It's generally used as both a measure of systematic risk and a performance measure. The market is described as having a beta of 1. The beta for a stock describes how much the stock's price moves compared to the market. If a stock has a beta above 1, it's more volatile than the overall market.
How do you find the beta and alpha of a stock?
Alpha = R – Rf – beta (Rm-Rf) R represents the portfolio return. Rf represents the risk-free rate of return. Beta represents the systematic risk of a portfolio. Rm represents the market return, per a benchmark.
What is beta in CAPM model?
Beta is the standard CAPM measure of systematic risk. It gauges the tendency of the return of a security to move in parallel with the return of the stock market as a whole. One way to think of beta is as a gauge of a security's volatility relative to the market's volatility.

What is beta in stock market?
Learn more... Beta is the volatility or risk of a particular stock relative to the volatility of the entire stock market. Beta is an indicator of how risky a particular stock is, and it is used to evaluate its expected rate of return.
What is beta analysis?
Beta analyzes a stock's volatility over a set period of time, without regard to whether the market was on an upswing or downswing. As with other stock fundamentals, the past performance it analyzes is not a guarantee of how the stock will perform in the future. Thanks!
What does it mean when the beta is lower than 1?
The risk of an index is fixed at 1. A beta of lower than 1 means that the stock is less risky than the index to which it's being compared. A beta of higher than 1 means the stock is more risky than the index to which it's being compared.
How to interpret beta?
Know how to interpret beta. Beta is the risk, relative to the stock market as a whole, an investor assumes by owning a particular stock. That's why you need to compare the returns of a single stock against the returns of an index. The index is the benchmark against which the stock is judged. The risk of an index is fixed at 1. A beta of lower than 1 means that the stock is less risky than the index to which it's being compared. A beta of higher than 1 means the stock is more risky than the index to which it's being compared.
What does it mean when the beta is negative?
Usually the rates of return are figured over several months. Either or both of these values may be negative, meaning that investing in the stock or the market (index) as a whole would mean a loss during the period. If only one of the two rates is negative, the beta will be negative.
How to calculate the return of a stock?
Begin calculating returns for the stock market index. 1 Since return is a calculation over time, you won't put anything in your first cell; leave it blank. You need at least two data points to calculate returns, which is why you'll start on the second cell of your index-returns column. 2 What you're doing is subtracting the more recent value from the older value and then dividing the result by the older value. This just gives you the percent of loss or gain for that period. 3 Your equation for the returns column might look something like this: = (B4-B3)/B3
How many data points do you need to calculate returns?
You need at least two data points to calculate returns, which is why you'll start on the second cell of your index-returns column. What you're doing is subtracting the more recent value from the older value and then dividing the result by the older value.
How to calculate beta of a stock?
Here is a straightforward formula for calculating the Beta Coefficient of a Stock: 1 Obtain the stock’s historical share price data. 2 Obtain historical values of a market index, e.g., S&P 500. 3 Convert the share price values into daily return values using the following formula: return = (closing share price − opening share price)/opening share price. 4 Convert historical stock market index values in a similar way. 5 Align the share return data with index return such that there is a 1-on-1 correspondence between them. For share price return, there should be a corresponding index return. 6 Using the SLOPE function in a financial calculator to find the slope between both arrays of data and the resultant figure is Beta.
What does beta mean in stocks?
Beta can give you an estimate of the stock’s risk and some idea of market volatility. Ideally, the Beta will tell you the difference between a stock’s risk and the risk of an entire index market.
What is the beta coefficient?
Generally, analysts regard the Beta Coefficient as a measure of systematic or “general market” risk. Analysts often use the mathematical symbol β to represent the Beta in calculations. To explain, systematic is the level of risk or volatility of equity in the entire market or index.
Why do analysts use the beta coefficient?
Analysts examine the Beta Coefficient, or Beta of stock, because the Beta measures risk and volatility. Specifically, the Beta can give you an estimate of the stock’s risk and some idea of market volatility. Ideally, the Beta will tell you the difference between a stock’s risk and the risk of an entire index market.
Why is beta a limited tool?
Hence, the Beta is a limited tool because it only measures some risks associated with individual stocks or indexes. However, a rough estimate of risk is better than no estimate of risk.
Can you use beta in stock analysis?
In the final analysis, the Beta is only one of many stock analysis tools you can use. In fact, some analysts and investors never use the Beta. On the other hand, there are many analysts who swear by the Beta. Hence using the Beta is a matter of choice.

Marketable Securities Marketable securities are unrestricted short-term financial instruments that are issued either for equity securities or for debt securities of a publicly listed company. The issuing company creates these instruments for the express purpose ...
What are the drawbacks of beta?
The largest drawback of using Beta is that it relies solely on past returns and does not account for new information that may impact returns in the future. Furthermore, as more return data is gathered over time, the measure of Beta changes, and subsequently, so does the cost of equity.
What is the benefit of using beta coefficient?
Advantages of using Beta Coefficient. One of the most popular uses of Beta is to estimate the cost of equity (Re) in valuation models. The CAPM estimates an asset’s Beta based on a single factor, which is the systematic risk of the market.
What is systematic risk?
Systematic Risk Systematic risk is that part of the total risk that is caused by factors beyond the control of a specific company or individual. Systematic risk is caused by factors that are external to the organization. All investments or securities are subject to systematic risk and therefore, it is a non-diversifiable risk.
How to find out if a stock has a beta of 2?
To begin, select the "Technical" tab within the "Filters" section. Under the "Beta" tab, select " Over 2" from the dropdown menu. This displays a list of stocks that have a beta higher than 2. Traders can add additional filters, such as country, exchange, and index.
What does it mean when a stock has a beta of 1?
If a stock has a beta above 1, it's more volatile than the overall market. For example, if an asset has a beta of 1.3, it's theoretically 30% more volatile than the market. Stocks generally have a positive beta since they are correlated to the market.
Why is the beta of a stock below 1?
If the beta is below 1, the stock either has lower volatility than the market, or it's a volatile asset whose price movements are not highly correlated with the overall market. The price of Treasury bills (T-bills) has a beta lower than 1 because T-bills don't move in relation to the overall market. Many consider stocks in the utility sector ...
What does beta mean in stock?
Beta is a statistical measure of the volatility of a stock versus the overall market. A beta above 1 means a stock is more volatile than the overall market. A beta below 1 means a stock is less volatile than the overall market. The S&P 500, Dow Jones Industrial Average, and Nasdaq 100 are frequently used beta measures.
What is beta in hedge funds?
Beta is an important concept for the analysis of hedge funds. It can show the relationship between a hedge fund’s returns and the market return. Beta can show how much risk the fund is taking in certain asset classes and can be used to measure against other benchmarks, such as fixed income or even hedge fund indexes.
How to calculate beta?
The beta coefficient is calculated by dividing the covariance of the stock return versus the market return by the variance of the market. Beta is used in the calculation of the capital asset pricing model (CAPM). This model calculates the required return for an asset versus its risk. The required return is calculated by taking the risk-free rate plus the risk premium. The risk premium is found by taking the market return minus the risk-free rate and multiplying it by the beta.
What is the most commonly used stock index?
The most commonly used stock index is the S&P 500. The S&P 500 is used as the measure because of the high number of large-cap stocks included in the index and the broad number of sectors included. The Dow Jones Industrial Average (DJIA) has also previously been the main measure of the market, but it has fallen out of favor since it only includes 30 ...

Both stock and the market or the benchmark will move in the opposite direction. Beta = 0: If the Beta is equal to zero, ...
What does a beta of 1 mean?
Beta of 1 implies that the volatility of the stock is exactly the same as that of the underlying market or the index in both qualitative and quantitative terms. Beta of greater than 1 implies that the stock is more volatile than the underlying market or index. A negative Beta is possible but highly unlikely.
What does it mean when the beta is greater than zero?
Beta > 0: If the Beta is greater than zero, then there is a strong direct relationship between the stock and the underlying market or the benchmark. Both stock and the market or the benchmark will move in the same direction. Some further insight is as follows:
What does it mean when the beta is 0?
Beta = 0: If the Beta is equal to zero, then this implies that there is no relation between the movement of the returns of the stock and the market or the benchmark, and hence both are too dissimilar to have any common pattern in price movements . Beta > 0: If the Beta is greater than zero, then there is a strong direct relationship between ...
Is a negative beta of gold a good thing?
A negative Beta is possible but highly unlikely. Most investors believe that gold and stock based on gold tend to perform better when the market dives. Whereas a Beta of zero is possible in the case of government bonds acting as risk-free securities providing a low yield to the investors.
What is risk free rate?
Hence, the risk-free rate as well is required to be brought to the same real terms, which is basically inflation-adjusted for the economy. Since the rate is mostly the long term government bonds – they are adjusted to the rate of inflation factor and provided for further use.

What is negative beta?
Beta is the calculation of change, i.e., the change in the stock relative to the change in the market. In theory, when investing in a high beta stock, an investor generally should demand a higher return.
Why is beta important?
The beta comes in to adjust that market premium as beta is positively correlated with the market. It helps us understand if a stock is more volatile—with a beta of greater than one (β>1)—or less volatile—with a beta of less than one (β<1) than the market. Movement relative to the market is risk that cannot be removed through diversification.
Is it possible to use the wrong beta?
And yes, that’s possible. But, also it could be the wrong beta to use too. Which is exactly why one of the top valuation mistakes is valuing a stock using the calculated beta—using a too high or too low beta, using Bloomberg’s beta, or using your own calculated beta will all help you arrive at vastly different metrics.
