High-beta stocks are supposed to be riskier but provide higher return potential. Conversely, low-beta stocks pose less risk but also offer lower potential returns. Beta is a component of the capital asset pricing model (CAPM), which is widely used to determine the rate of return that shareholders might reasonably expect based on perceived investment risk. A beta coefficient can measure the volatility of an individual stock compared to the systematic risk of the entire market. In statistical terms, beta represents the slope of the line through a regression of data points. In finance, each of these data points represents an individual stock’s returns against those of the market as a whole.

Professional portfolio managers calculate alpha as the rate of return that exceeds the model’s prediction or comes short of it. They use a capital asset pricing model (CAPM) to project the potential returns of an investment portfolio. In order to make sure that a specific stock is being compared to the right benchmark, it should have a high R-squared value in relation to the benchmark.

The best approach is to have a balance of high- and low-volatility assets. Besides predicting a stock’s volatility, the beta can also offer insights into a stock’s historical price movements. The question (What is beta in stocks?) is worth asking, as the parameter is simple but insightful. Here are our thoughts on the interpretation and insights on stocks beta.

1. The content created by our editorial staff is objective, factual, and not influenced by our advertisers.
2. By identifying highly volatile stocks and comparing them with your risk tolerance, you can determine which assets to add to your portfolio.
3. For example, it would not be optimal to find out a stock’s Beta by comparing it to a commodity index like MCX or any type of currency pair.
4. Many experts agree that while Beta provides some information about risk, it is not an effective measure of risk on its own.
5. Thus, when Berkshire Hathaway BRK.A and Enron each faced a losing stock market in 2001, while possessing similar betas, Warren Buffett’s firm managed a small profit while the latter lost 97%.

Her expertise is in personal finance and investing, and real estate.

The latter relates a stock’s volatility with the expected returns, allowing investors to predict the return on investment. This approach considers the risk of trading the stock and the capital. Investors keen to bag big capital gains or day traders looking to make a quick buck from fluctuating share prices would be more interested in high-beta stocks. The share prices of these companies historically have a tendency to jump around quite a bit.

Defining Beta

It measures the systematic risk of a security or a portfolio compared to an index like the S&P 500. Many growth stocks would have a beta over 1, probably much higher. A T-bill would have a beta close to zero because its prices hardly move relative to the market as a whole. The beta of an asset is compared best investment opportunities to the market as a whole, usually the S&P 500. By definition, the value-weighted average of all market-betas of all investable assets with respect to the value-weighted market index is 1. This is in contrast to unsystematic risk, which is the risk of investing in a particular company or industry.

It’s used to evaluate the expected risks and returns of a portfolio, or to see whether a specific investment would be a good fit for a portfolio in terms of expected risks and returns. Essentially, beta expresses the trade-off between minimizing risk and maximizing return. This means it is two times as volatile as the overall market. On the other hand, if the market declines 6%, investors in that company can expect a loss of 12%. In investing, beta does not refer to fraternities, product testing, or old videocassettes.

The role of beta in asset allocation strategies (e.g., stocks, bonds, and cash)

While beta measures volatility, it is not conclusive for a comprehensive risk assessment. The previous section introduced a few metrics to help you have a more holistic view of the stock’s tendencies. However, those are even more unpredictable than those with beta values above one.

It’s tempting to just look at the number on your brokerage’s app or website and assume you know how volatile that particular stock or asset is. But those assumptions require verification because beta isn’t universal. If you’re still asking, «What is alpha and beta in stocks?» here’s an example to help better expand the concept.

Low Beta

First, beta is calculated using historical market data so it’s less useful for investors who want to predict future movements in prices. Next, calculate the covariance for stock and index prices. Covariance is how you measure a changing relationship between two entities. In this case, covariance will show you how changes in stock returns relate to changes in market returns. Beta can also be a screening tool for short-term traders since day and swing trading requires volatile assets with prices that move quickly (i.e., penny stocks).

What is stock beta used for in terms of portfolio analysis?

It is obtained as the slope of the fitted line from the linear least-squares estimator. The OLS regression can be estimated on 1–5 years worth of daily, weekly or monthly stock returns. The arbitrage pricing theory (APT) has multiple factors in its model and thus requires multiple betas. If you’re investing for the long term, you may want to factor in a time frame of about five to 10 years.
