what is beta


A security plotted below the SML is overvalued because the investor would be accepting a lower return for the amount of risk assumed. However, the beta calculation can’t detect any unsystematic risk. However, since beta is calculated using historical data points, it becomes less meaningful for investors looking to predict a stock's future movements. Can apply to many situations, but often refers to scenarios with women. It also provides insights about how volatile–or how risky–a stock is relative to the rest of the market. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'beta.'

You can learn more about the standards we follow in producing accurate, unbiased content in our In fund management, measuring beta is thought to separate a manager's skill from his or her willingness to take risk. Letters that arose from beta include the Roman letter ⟨B⟩ and the Cyrillic letters ⟨Б⟩ and ⟨В⟩.
In fact, stock A has better return in every possible case.

The choice of the index need not reflect the portfolio under question; e.g., beta for gold bars compared to the S&P 500 may be low or negative carrying the information that gold does not track stocks and may provide a mechanism for reducing risk. Sometimes the market is defined as "all investable assets" (see By definition, the market itself has a beta of 1, and individual stocks are ranked according to how much they deviate from the macro market (for simplicity purposes, the A stock with a beta of 2 has returns that change, on average, by twice the magnitude of the overall market; when the market's return falls or rises by 3%, the stock's return will fall or rise (respectively) by 6% on average.

Therefore, an asset may have different betas depending on which benchmark is used.

Portable alpha is a strategy that seeks a higher portfolio return by splitting assets into portions selected for their alpha and beta characteristics. Just a number is useless if the benchmark is not known. Beta is also less useful for long-term investments since a stock's volatility can change significantly from year to year, depending upon the company's growth stage and other factors.


Technology stocks and small cap stocks tend to have higher betas than the market benchmark. The beta commonly quoted in Multiple-factor models contradict CAPM by claiming that some other factors can influence return, therefore one may find two stocks (or funds) with equal beta, but one may be a better investment. In this phase of software development, applications are subjected to real world testing by the intended audience for the software. Beta can also be negative, meaning the stock's returns tend to move in the opposite direction of the market's returns. We'll send you an email containing your password. In software development, a beta test is the second phase of software testing in which a sampling of the intended audience tries the product out.Beta is the second letter of the Greek alphabet. The returns on A, B and the market follow the probability distribution below: It's usually by invitation and you report back any issues you find. For beta to provide any useful insight, the market that is used as a benchmark should be related to the stock. Ultimately, an investor is using beta to try to gauge how much risk a stock is adding to a portfolio. Beta is also a measure of the covariance of a stock with the market.

So, adding a down-trending stock with a low beta decreases risk in a portfolio only if the investor defines risk strictly in terms of volatility (rather than as the potential for losses). On comparison of the benchmark index for e.g. Beta (Ryan Hurst) had part of his mask scratched away in TWD Season 10, Episode 12 (titled "Walk With Us"), revealing that he is somewhat of a celebrity within the show universe. Adding a stock to a portfolio with a beta of 1.0 doesn’t add any risk to the portfolio, but it also doesn’t increase the likelihood that the portfolio will provide an excess return.

(However, because beta also depends on the correlation of returns, there can be considerable variance about that average; the higher the correlation, the less variance; the lower the correlation, the higher the variance.) A beta is a male who, instead of being alpha and manning up, completely bitches out. I'm not sure if that distinction is still made, however.I know you can sign up for some gaming sites to be a beta tester. The Treynor ratio, also known as the reward-to-volatility ratio, is a performance metric for determining how much excess return was generated for each unit of risk taken on by a portfolio. If the security's risk versus expected return is plotted above the SML, it is undervalued because the investor can expect a greater return for the inherent risk. Beta testing can be considered "pre-release testing." We also reference original research from other reputable publishers where appropriate. Lower-beta stocks pose less risk but generally offer lower returns. For example, calculating a bond ETF's beta using the S&P 500 as the benchmark would not provide much helpful insight for an investor because bonds and stocks are too dissimilar. However, according to the "Beta coefficient" redirects here. The first formula is exact, while the second one is only valid for small δ. Originally, the term Beta testing is also sometimes referred to as user acceptance testing (For in-house testing, volunteers or paid test subjects use the software. Some stocks have negative betas. For example, X could be U.S. stocks, while Y could be stocks of a different country, or bonds. For example, to hedge away the market-risk of a stock with a market beta of 2.0, an investor could short $2,000 in the stock market for every $1,000 invested in the stock.
