Beta
|
- A measure of the volatility of a stock relative to the overall market. a beta of less than one indicates lower risk than the market; a beta of more than one indicates higher risk than the market. nasdaq.com uses the s&p 500 as the underlying index to meas
- Also known as type-2 error, beta is the complement to power : beta = (1-power). this is the probability that a statistical test will generate a false-negative error : failing to assert a defined pattern of deviation from a null pattern in circumstances wh
- A measure of the volatility of a security compared to a given index or overall market.
- Бета - изменение относительной волатильности акций. сравнение движение цен конкретной акции с фондовым индексом s&p 500 имеет “бету” со значением 1. акция с “бетой” больше 1 - более неустойчива, а если меньше 1 - более устойчива, чем рынок в среднем;

- The measure of an asset`s risk in relation to the market (for example, the s&p500) or to an alternative benchmark or factors. roughly speaking, a security with a beta of 1.5, will have move, on average, 1.5 times the market return. [more precisely, that stock`s excess return (over and above a short-term money market rate) is expected to move 1.5 times the market excess return).] according to asset pricing theory, beta represents the type of risk, systematic risk, that cannot be diversified away. when using beta, there are a number of issues that you need to be aware of: (1) betas may change through time; (2) betas may be different depending on the direction of the market (i.e. betas may be greater for down moves in the market rather than up moves); (3) the estimated beta will be biased if the security does not frequently trade; (4) the beta is not necessarily a complete measure of risk (you may need multiple betas). also, note that the beta is a measure of co-movement, not volatility. it is possible for a security to have a zero beta and higher volatility than the market.

Volatility, английский
- The degree of price fluctuation for a given asset, rate, or index; usually expressed as a variance or standard deviation.
- A statistical measure of the tendency of a market price or yield to vary over time.
- Волатильность, относительная скорость, с которой цена перемещается вверх и вниз; мера степени изменений рыночной стоимости ценных бумаг, определяемая за период в 52 недели (12 месяцев) и измеряемая в процентах. для того чтобы измерить волатильность, нужно
- This property describes the degree and rate at which a liquid will vaporize under given conditions of temperature and pressure. when liquid stability changes, this property is often reduced in value.
- Относительная скорость, с которой цена перемещается вверх и вниз. вычисляется годовое среднеквадратичное отклонение ежедневного изменения цены.
- Property of having a low boiling point or temperature of sublimation at normal pressure. likewise, having a high vapor pressure at ambient conditions.
- A measure of risk based on the standard deviation of the asset return. volatility is a variable that appears in option pricing formulas, where it denotes the volatility of the underlying asset return from now to the expiration of the option. there are volatility indexes. such as a scale of 1-9; a higher rating means higher risk.
- Нестабильность
- Describes how easily a substance will vaporize (turn into a gas or vapor).
- The property of a liquid that defines its evaporation characteristics. of two liquids, the more volatile will boil at a lower temperature and will evaporate faster when both liquids are at the same temperature. the volatility of petroleum products can be evaluated by tests for flash point, vapor pressure, distillation and evaporation rate.

Probability, английский
- Probability can be generally defined as a measure of how likely some event will occur. the event could be an explosion, a lottery win or perhaps cancer induction. mathematically speaking, the value of probability varies between 0 and 1 where 0 means an ev
- Вероятность. возможность.
- The probability of an event is a number between zero and 100%. the meaning (interpretation) of probability is the subject of theories of probability, which differ in their interpretations. however, any rule for assigning probabilities to events has to satisfy the axioms of probability.
- Вероятность
- Вероятность probability sample, syn. random sample
- Вероятность. мера случайности появления конкретного события. например, вероятность случайного выбора из популяции человека с конкретным качеством соответствует доле людей в популяции, обладающих этим качеством.
- Вероятность; возможность
- Вероятность; обеспеченность (гидрологической величины) ~ of no-failure вероятность безотказной работы
- Probability is a method for representing uncertainty about propositions or events. it represents the uncertainty about a proposition on a scale from 0 to 1, with a 0 representing complete certainty that the proposition is false or an event will not occur and a value of one will represent the opposite. formally, a probability measure is one that follows kolmogorov`s axioms. there are two main schools of thought on the meaning of probability. frequentists take a narrow interpretation of probability allowing only hypothetically repeatable events or experiments as being quantifiable by probability, while bayesians take a broader interpretation that allows reasoning about "one-shot" events and propositions based on the current knowledge about nature. the bayesian interpretation is most commonly used in artificial intelligence, while the frequentist interpretation is most commonly taught in statistics courses. the label "bayesian" arises from the central role that the bayes theorem plays in this use of probability. it allows one to reason from effects to causes and encourages the use of probability measures to describe supposedly fixed events or propositions which frequentists disallow. the probability for these events reflects one`s state of knowledge about the event, rather than being an assertion that the unknown event can vary. for example, a bayesian would have no qualms about making statements about the probability that a given die, rolled and hidden from his sight is, for example, a six. a frequentist would be unable to make such a statement, preferring to talk about his confidence in the method when applied to a hypothetically large number of repeated experiments. in the end, they would act in similar ways. when the long run data are available, bayesians and frequentists end up with the same estimates. see also: bayes theorem, kolmogorov`s axioms.
- Вероятность. математическое измерение возможности появления неко-его события, выраженное в виде дроби или процента [30]. значения статистической вероятности лежат в пределах от 1 или 100 процентов (всегда) до 0 или 0 процентов (никогда) [20]. наибольшее приближение к истинной вероятности дает относитель-ная частота события, полученная на основе большой серии измерений или результа-тов [33]. вероятность может быть также определена как выражение в некоторой неопределимой форме "степени уверенности" или как предельная частота события в бесконечной случайной последовательности [49].
- The likelihood of something happening. for example, sale being made.
