Companies whose share prices were less volatile than the S&P 500 will have a beta value under 1.0. Conversely, share prices that were more volatile than the S&P 500 will have beta values over 1.0. The overall market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. For beta to provide useful insight, the market used as a benchmark should be related to the stock. For example, a bond ETF’s beta with the S&P 500 as the benchmark would not be helpful to an investor because bonds and stocks are too dissimilar.

Beta effectively describes the activity of a security’s returns as it responds to swings in the market. It is used in the capital asset pricing model (CAPM), which describes the relationship between systematic risk and expected return for assets. CAPM is used to price risky securities and to estimate the expected returns of assets, considering the risk of those assets and the cost of capital. Beta quantifies a stock’s sensitivity to market movements, indicating its risk level. A beta greater than 1 signifies higher volatility compared to the market, while a beta less than 1 suggests lower volatility. On the other hand, alpha measures a stock’s risk-adjusted performance, indicating its excess return above the expected return based on its beta.
Beta coefficients are a fundamental concept in statistics, particularly in the context of regression analysis. They represent the degree of change in the dependent variable for every one-unit change in the independent variable, holding all other variables constant. This measure is crucial for understanding the strength and direction of relationships between variables in a dataset.
How Does Beta Measure a Stock’s Market Risk?
Investors can still try to minimize the level of exposure to systematic risk by looking at a stock’s beta, or its correlation of price movements to the broader market as a whole. Beta coefficients have a wide range of applications across various fields, including economics, finance, healthcare, and social sciences. They are used to assess risk in financial models, evaluate the effectiveness of interventions in healthcare studies, and understand consumer behavior in marketing research. The versatility of beta coefficients makes them an invaluable tool for researchers and practitioners seeking to leverage data for strategic insights.
What is Beta Coefficient?
- While the concept of risk is hard to factor in stock analysis and valuation, one of the most popular indicators is a statistical measure called beta.
- Conversely, low-beta investments might appeal to conservative investors looking for more stable, albeit potentially lower, returns.
- If Apple Inc’s (AAPL) beta is 1.46, it indicates that the stock is highly volatile and 46% more likely to respond to market movement.
- The higher the value, the more the company tends to fluctuate in value.
That is, if a portfolio consists of 80% asset A and 20% asset B, then the beta of the portfolio is 80% times the beta of asset A and 20% times the beta of asset B. Most fixed income instruments and commodities tend to have low or zero betas; call options tend to have high betas; and put options and short positions and some inverse ETFs tend to have negative betas. For a company with a negative β, it means that it moves in the opposite direction of the market. Theoretically this is possible, however, it is extremely rare to find a stock with a negative β.
When the market rises, the negative beta tends to fall, and the negative beta will tend to rise when the market falls. In practice, the choice of index makes relatively little difference in the market betas of individual assets, because broad value-weighted market indexes tend to move closely together. A security’s beta is calculated by dividing the wordpress developer resources official wordpress developer resources product of the covariance of the security’s returns and the market’s returns by the variance of the market’s returns over a specified period. The calculation helps investors understand whether a stock moves in the same direction as the rest of the market.

A stock with a negative beta means that it is inversely correlated with market movements. For example, an inverse ETF tracking the S&P 500 would have a negative beta. The beta coefficient measures the volatility of a stock with respect to the broader market. When measuring the beta coefficient, analysts use the S&P 500 as the benchmark index to compare it to. Beta can be calculated by dividing the asset’s standard deviation of returns by the market’s standard deviation.
Adding this type of stock to a portfolio will raise its risk, but it may also improve its expected return. Visualizing beta coefficients can enhance understanding and communication of regression results. Common methods include bar charts and coefficient plots, which allow stakeholders to quickly grasp the relative importance of different predictors.
And if you’d like to begin investing but need help picking the right investment account for you, we have a great broker comparison tool that will make that choice easier. The beta coefficient is a financial metric that measures the volatility of a stock with relation to the broader market, which implies the benchmark index of the United States stock market – the S&P 500. Many consider stocks in the utility sector to have betas less than 1 since they’re not very volatile. Gold, on the other hand, is quite volatile but has tended to move inversely to the market. Lower beta stocks with less volatility do not carry as much risk, but they generally provide less opportunity for a higher return. Beta measures a stock’s volatility, the degree to which its price fluctuates in relation to the overall stock market.
The well-worn definition of risk is the possibility of suffering a loss. Of course, when investors consider risk, they are thinking about the chance that the stock they buy will decrease in value. The trouble is that beta, as a proxy for risk, doesn’t distinguish between upside and downside price movements. For most investors, downside movements are a risk, while upside ones mean opportunity.
It enables investors to compare and select assets aligned with their risk tolerance and investment objectives. Beta can be used to indicate the contribution of an individual asset to the market risk of a portfolio when it is added in small quantity. It refers to an asset’s non-diversifiable risk, systematic risk, or market risk. Levered beta (equity beta) load balancing between liquidity providers using ticktrader liquidity aggregator is a measurement that compares the volatility of returns of a company’s stock against those of the broader market. In other words, it is a measure of risk, and it includes the impact of a company’s capital structure and leverage.
How Beta Measures Systematic Risk
It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM). A company with a higher beta has greater risk and also greater expected returns. To calculate the beta of a security, the covariance between the return of the security and the return of the market must be known as well as the variance of the market returns. The covariance of the return of an asset with the return of the benchmark is divided by the variance of the return of the benchmark over a certain period. Investors must ensure a specific stock is compared to the right benchmark and review the R-squared value to the benchmark. R-squared is a statistical measure that compares the security’s historical price movements to the benchmark index.
Company
An investor uses beta to gauge how much risk a stock adds to a portfolio. While a stock that deviates very little from the market doesn’t add a lot of risk to a portfolio, it also doesn’t increase the potential for greater returns. Beta measures a stock’s correlation to the market, which can help team evolution dash for ca$h project its returns. Meanwhile, alpha compares a particular stock’s actual performance to the market’s performance. A beta value greater than 1.0 signifies that the theoretical volatility of the security’s price exceeds that of the market.
