It’s a numerical value that signifies how much a stock price jumps around. The higher the value, the more the company tends to fluctuate in value. A beta of 1.0 means the stock over the allocated time frame moved similar to the rest of the market. The well-worn definition of risk is the possibility of suffering a loss.
These kinds of stocks historically tend to not fluctuate much in value. They are companies that consistently deliver steady revenues and profits in times of economic expansion and hardship. Positive or negative surprises are lacking and valuations are based on very realistic expectations that how to buy shiba floki the company has a history of reaching.
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. Alpha and beta are fundamental concepts in finance that help investors measure and understand the performance and risk of investments relative to the broader market. Beta, often considered first, quantifies an asset’s volatility or systematic risk compared to the market as a whole.
These stocks have higher returns than the S&P 500, according to the Fama and French Three-Factor Model. In this case, a small-cap value index might be a better benchmark than the S&P 500. We often hear the terms alpha and beta when talking about investments. These are two different measures that are part of the same equation derived from a linear regression.
Levered beta, also known as equity beta or stock beta, is the volatility of returns for a stock, taking into account the impact of the company’s leverage from its capital structure. It compares the volatility (risk) of a levered company to the risk of the market. 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.
How Can Investors Use Alpha in Their Strategies?
For instance, the Dow Jones Industrial Average, which focuses on technology, would be more appropriate when analyzing a technology stock than the S&P 500, which represents a broader market. However, suppose the fund manager then underperforms the market by 2% over the next three years.

What is a good beta for a stock?
Don’t worry if that sounds complicated, we’ll explain it all in this article. High β – A company with a β that’s greater than 1 is more volatile than the market. For example, a high-risk technology company with a β of 1.75 would have returned 175% of what the market returned in a given period (typically measured weekly). Similarly, a high beta stock that is volatile in a mostly upward direction will increase the risk of a portfolio, but it may increase gains.
Equity β assesses the risk of a company’s equity by considering the impact of debt and capital structure on the stock. Β is based on previous data, which could not predict future stock movements correctly. So please consider other elements when choosing an investment strategy. Download historical security prices for the asset’s β you want to calculate.
- In this case, covariance will show you how changes in stock returns relate to changes in market returns.
- Companies in certain industries tend to achieve a higher β than companies in other industries.

- In a sense, it tells investors whether an asset has consistently performed better or worse than its beta predicts.
Small-cap and technology stocks typically have higher betas than the market introducing broker vs white label benchmark. Adding this type of stock to a portfolio will raise its risk, but it may also improve its expected return. Another troubling factor is that past price movement is a poor predictor of the future. Betas are merely rear-view mirrors, reflecting very little of what lies ahead. Furthermore, the beta measure on a single stock tends to flip around over time, which makes it unreliable. Granted, for traders looking to buy and sell stocks within short time periods, beta is a fairly good risk metric.
How to Calculate Beta
A positive alpha indicates outperformance, while a negative alpha suggests underperformance relative to the benchmark. In practice, the choice of index makes relatively little difference in the market betas of individual assets, because broad value-weighted physical security market indexes tend to move closely together. A portfolio consisting entirely of high-beta stocks can be highly volatile and subject to significant market fluctuations.
By including a mix of assets with varying beta values, investors can create a balanced portfolio that aligns with their risk preferences. A well-diversified portfolio can reduce overall risk and improve the chances of achieving a consistent return on investment. Taking a more sophisticated approach and using the CAPM, you can understand how the level of systemic risk impacts the expected return. In the short-term, beta can give frequent traders an indication of risk. The most rudimentary way to use beta is to realize that high beta stocks could increase your portfolio risk while low beta stocks could reduce it.
Very few investors have true alpha, and it typically takes a decade or more to be sure. Buffett focused on value investing, dividend growth, and “growth at a reasonable price” strategies during his career. A study of Buffett’s alpha found that he tended to use leverage with high-quality and low-beta stocks. The first, and simplest, way is to use the company’s historical β or just select the company’s beta from Bloomberg.

A stock’s volatility can change significantly over time, depending on a company’s growth stage and other factors. A security’s beta is calculated by dividing the 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. It also provides insights into how volatile–or how risky–a stock is relative to the rest of the market. Beta effectively describes the activity of a security’s returns as it responds to swings in the market.
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. A security’s β should only be used when its high R-squared value is higher than the benchmark. The R-squared value measures the percentage of variation in the share price of a security that can be explained by movements in the benchmark index. For example, a gold ETF will show a low β and R-squared in relation to a benchmark equity index, as gold is negatively correlated with equities.
