A stock with a very low beta could have smaller price swings, yet still be in a long-term downtrend. So, adding a down-trending stock with a low beta decreases the risk in a portfolio only if the investor defines risk strictly in terms of volatility and not potential losses. When assessing risk, it’s important to consider all of the factors involved and not just beta. Beta can be a helpful tool for investors, but it’s important to remember that it has its limitations.
The risk-free rate is the same as in the Beta formula, while the Beta that you’ve already calculated is simply placed into the CAPM formula. Beta is an essential component of the CAPM because without it, riskier securities would appear more favorable to prospective investors as their risk wouldn’t be accounted for in the calculation. Therefore, if the market returned 10% in a year, high Beta names would, on average, produce 13.8% returns. However, during down years, high Beta names capture 243% of the market’s returns.
In other words, it is a measure of risk, and it includes the impact of a company’s capital structure and leverage. Equity beta allows investors to assess how sensitive a security might be to macro-market risks. For example, a company with a β of 1.5 denotes returns that are 150% as volatile as the market it is being compared to.
How can beta be negative? closed
- The numerator is the covariance of the asset in question while the denominator is the variance of the market.
- In a similar example, if the market lost 10% during a year, the group of high Beta names would have returned -24.3%.
- Equity beta allows investors to assess how sensitive a security might be to macro-market risks.
- Investors must ensure a specific stock is compared to the right benchmark and review the R-squared value to the benchmark.
- This article will discuss how to calculate beta, the difference between high-beta and low-beta stocks, as well as individual analysis of the one stock in the S&P 500 Index with negative beta right now.
The ionizations they cause are very close together – they can release all their energy in a few cells. Second, the main assumptions of regression are normality, homoscedasticity, and absence of multicollinearity. If the data form a straight line along the diagonal, you can assume normality. To assess homoscedasticity, the researcher can create a scatterplot of standardized residuals verses standardized predicted values.
It’s possible for stock to have high beta one year and a low beta the next. So, while beta can be helpful in assessing risk, it’s not the only factor you should consider. For example, it doesn’t take into account the size of the movements, just how often they occur.
It compares the volatility (risk) of a levered company to the risk of the market. The beta (β) of an investment security (i.e., a stock) is a measurement of its volatility of returns relative to the entire market. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM).
Relationship between own risk and beta risk
- They are still stocks, so the market price will be affected by overall stock market trends, even if this does not make sense.
- It can come from unstable atoms that undergo radioactive decay, or it can be produced by machines.
- An index that represents all of the market is a CAPM assumption, but in reality $m$ is typically some stock index (like the S&P 500, which represent U.S. large cap stocks).
- X-rays are similar to gamma rays in that they are photons of pure energy.
- Beta only looks at a stock’s past performance relative to the S&P 500 and does not predict future moves.
- Beta-emitters are most hazardous when they are inhaled or swallowed.
R-squared is a statistical measure that compares the security’s historical price movements to the benchmark index. 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 can beta be negative low beta and R-squared relationship with the S&P 500.
Calculation
Negative-beta stocks could be particularly appealing in a recession or a market downturn. Beta is one of the most widely-used measures of stock market volatility. Beta can be a valuable tool for investors when analyzing stocks for inclusion in their portfolios. It can be, but it’s important to remember that beta is only one factor to consider when assessing risk. Other factors, such as the size of the company, the industry it operates in, and overall market conditions can also affect risk.
A positive beta coefficient indicates that for every 1-unit increase in the predictor variable, the outcome variable will increase by the beta coefficient value. Conversely, a negative beta coefficient means that for every 1-unit increase in the predictor variable, the outcome variable will decrease by the beta coefficient value. When the beta coefficient is not statistically significant (i.e., the t-value is not significant), the variable does not significantly predict the outcome. For example, if the beta coefficient is .80 and I statistically significant, then for each 1-unit increase in the predictor variable, the outcome variable will increase by .80 units. 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.
Can beta have a negative value?
Here is the answer. Yes, beta can be negative. To see how and why, consider what beta measures: the risk added by an investment to a well diversified portfolio. By that definition, any investment that when added to a portfolio, makes the overall risk of the portfolio go down, has a negative beta.

Similarly, a β of more than 1 indicates that the security is more volatile than the market as a whole. Companies in certain industries tend to achieve a higher β than companies in other industries. In this case, our security has an expected return of 14% against an expected benchmark return of 8%.
These particles are emitted by certain unstable atoms such as hydrogen-3 (tritium), carbon-14 and strontium-90. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.
Can beta angle be negative?
Beta angles where the sun is north of the orbit plane are considered positive — beta angles where the sun is south of the orbit are considered negative.
Investors who beta to evaluate a stock also evaluate it from other perspectives—such as fundamental or technical factors—before assuming it will add or remove risk from a portfolio. As you can see, these stocks have beta values that range from 1.17 to 2.00. Alphabet, Apple, and Facebook are all large companies with stable earnings and a history of consistent growth. Factors such as the size of the company, the industry it operates in, and the overall market condition affect a stock’s beta. Estimators of market-beta have to wrestle with two important problems.
However, it’s important to remember that beta is only one factor to consider when assessing risk. Other factors, such as the size of the company, the industry it operates in, and overall market conditions, can also affect risk. This beta value shows security price volatility higher than market. So a beta value of 1.4 would indicate that the volatility of the stock is 40% higher than market. Adding this stock to your portfolio will cause risk to increase. Beta measures a stock’s volatility, the degree to which its price fluctuates in relation to the overall stock market.
What is positive and negative beta?
For instance, a stock with a beta of -1 will decrease in value by 1% for every 1% increase in the general stock market, and vice versa. In short, positive betas indicate that stocks move in the same direction as the market, while negative betas signify a negative correlation.
