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.
While beta can offer useful information when evaluating a stock, it does have some limitations. Beta can determine a security's short-term risk and analyze volatility. However, beta is calculated using historical data points and is less meaningful for investors looking to predict a stock's future movements for long-term investments. A stock's volatility can change significantly over time, depending on a company's growth stage and other factors.
Beta can provide some risk information, but it is not an effective measure of risk. Beta only looks at a stock's past performance relative to the S&P 500 and does not predict future moves. It also does not consider the fundamentals of a company or its earnings and growth potential.
A Beta of 1.0 for a stock means it has been as volatile as the broader market. If the index moves up or down 1%, so too would the stock, on average. Betas larger than 1.0 indicate greater volatility - so if the beta were 1.5 and the index moved up or down 1%, the stock would have moved 1.5%, on average. Betas less than 1.0 indicate less volatility: if the stock had a beta of 0.5, it would have risen or fallen just half a percent as the index moved 1%.
Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word *bayt ('house', compare Arabic: بيت bayt and Hebrew: בית byit). In Greek, the name was βῆτα bta, pronounced [bɛ̂ːta] in Ancient Greek. It is spelled βήτα in modern monotonic orthography and pronounced [ˈvita].
Beta should not be confused with standard deviation (or the semi-variance, which considers only negative returns): the preferred measure of the "riskiness" (historical volatility of returns) of a financial asset or a portfolio in isolation.
Beta can be calculated as the covariance of a financial asset (or portfolio) with its benchmark index, divided by the variance of the benchmark index. Since the industry of finance gravitates towards return generating activities, typically the historical returns (percentage changes) are used in the calculations Beta values (among others).There are numerous other methods a financial analyst can employ to derive Beta values if historical prices are not available.Beta values change over time (company restructuring; industry sentiment; endo/exogenous factors). Beta values also vary, conditional on the time period used in calculating a Beta value. Beta values can be negative, which infers the existence of financial assets which historically, tended to move in opposite directions to one another by some unit value. It would seem these are the optimal "hedges" to offset market-draw-downs, during periods of market-stress and poor liquidity Beta values can vary dramatically, and previously low or even negative correlations converge to "1".
Beta male, or simply beta, is a slang term for men derived from the designation for beta animals in ethology, along with its counterpart, alpha male.[4][5] The term has been used as a pejorative self-identifier among members of manosphere communities, particularly incels, who do not believe they are assertive or traditionally masculine, and feel overlooked by women.[6][7] It is also used to negatively describe other men who are not assertive, particularly in heterosexual relationships.
In some high-quality typesetting, especially in the French tradition, a typographic variant of the lowercase letter without a descender is used within a word for ancient Greek: βίβλος is printed βίϐλος.[8]
"Beta" can be used to refer to several consumer and professional videotape formats developed by Japan's Sony Corporation. Although similarly named, they are very different in function and obsolescence.
Android Beta for Pixel offers you a simple way to try pre-release versions of Android, and test drive our new features. The feedback you provide will help us identify and fix issues, and make the platform even better. Enrolled devices will automatically receive updates for the latest beta version of Android. Learn more about eligible devices.
You will not be able to unenroll and revert back to a stable public version of Android without first wiping all locally saved data on your device. You may also encounter issues restoring a backup. We recommend reviewing the latest release notes for Pixel phones before enrolling in Android Beta.
Your device eligibility and current build determine which program options are available for enrollment. Devices on a public stable build will see multiple program options to select from when more than one beta program is available.
Important: If, after opting out, you only see one program option to enroll in, you will need to first apply the stable public version (will require a data wipe) in order to see multiple enrollment options. This only applies when more than one beta program is available.
View devices to find the device you want to switch and click Opt out. Your device will receive an update within 24 hours that will wipe all user data and install the latest stable public version of Android. Once you install the public update, your device is ready to enroll in another beta program.
Important: Your device may get automatically removed from the beta program it is enrolled in and either get moved to the public release track or to another beta program track for the following reasons:
Beta blockers are not recommended as a first treatment if you have only high blood pressure. Beta blockers are not usually used for high blood pressure unless other medicines, such as diuretics, have not worked well. A beta blocker may be one of several medicines used to lower blood pressure.
If you have diabetes, beta blockers may block signs of low blood sugar, such as a rapid heartbeat. It's important to check your blood sugar regularly if you have diabetes and you're taking a beta blocker.
Some beta blockers can affect cholesterol and triglyceride levels. They can cause a slight rise in triglycerides, a type of fat in the blood. Beta blockers also can cause a modest decrease in good cholesterol, called high-density lipoprotein (HDL) cholesterol. These changes may only last for a short time.

Men who have been taking beta carotene supplements for 15 or more years are considerably less likely to experience cognitive decline than other males, researchers from Harvard Medical School reported in Archives of Internal Medicine (November 2007 issue).
Their study, involving 4,052 men, compared those on beta carotene supplements for an average of 18 years to others who were given placebo. Over the short-term, they found no difference in cognitive decline risk between the two groups of men, but in the long-term it was clear that beta carotene supplements made a significant difference.
They measured the FEV1 of 535 participants and measured their beta carotene blood levels. FEV1 measures how much air you can breathe out in one go. They found that those with high beta carotene levels had much slower decline in FEV1 measures.
A French study involving adult females published in the Journal of the National Cancer Institute (September 2005 issue) found that smokers with high beta carotene levels had a higher risk of lung cancer and other smoking-related cancers than other smokers. They also found that non-smokers with high beta carotene intake had a lower risk of lung cancer.
