Volatility is a measure of the amount by which an asset has fluctuated, or is expected to fluctuate, in a given period of time. Assets with greater volatility exhibit wider price swings and their options are higher in price than less volatile assets. Volatility is not equivalent to BETA.

The volatility of a stock describes the extent of its variance over time. See standard deviation.

Fluctuation in share prices. Volatility is a measure of risk, as the higher the volatility, the less certain an investor can be of a return.

Volatility is not influenced by the direction of the change; it does not matter whether the price rises or falls.

A term used to describe large price fluctuations in a specific security.

Volatility (variability, inconstancy): This term characterizes a degree of variability of an exchange rate during the certain period of time. For example, when in the market there are sharp fluctuations of a rate with big amplitude then the volatility is said to high.

Term used to describe the size & frequency of price fluctuations of a security, index, etc. See also Beta.

Measure of the variability of the market prices, used to assist the setting of margin rates.

Volatility is a measure of the variability of returns over a chosen time-period. It reveals the extent by which the daily/weekly/monthly price changes from the average. A low percentage volatility shows that the price has stayed quite close to the average whereas a high percentage volatility shows that the price has moved up and down a lot over the time-period. So volatility is a market measure of uncertainty â€“ investors keep changing their minds as to the value of the share, which reflects uncertainty surrounding the companyâ€™s future profit potential. As such, it's an excellent indicator of investment risk.

The degree of ups and downs of the price of an investment.

A measure of the amount by which an underlying is expected to fluctuate in a given period of time. Volatility is a primary determinant in the valuation of options premiums and time value. There are two basic kinds of volatility, implied and historical (statistical). Implied volatility is calculated by using an option pricing model (Black-Scholes for stocks and indices and Black for futures). Historical volatility is calculated by using the standard deviation of underlying asset price changes from clos e to close trading going back 21 to 23 days.

The degree to which financial instruments or markets are subject to market fluctuations. Volatility is measured by an annualised Standard Deviation of the underlying. The two most common methods of assessing volatility levels are Historical and Implied Volatility. The volatility level is a main factor influencing option premiums. In the bond markets, volatility refers to modified duration.

The general variability of a portfolio's value resulting from price fluctuations of its investments. In most cases, the more diversified a portfolio is, the less volatile it will be.

It is a measure for the fluctuation range of the underlying price. The greater the volatility, the higher the option price. The historic volatility is based on past data. It is often expressed as a percentage and computed as the annualized standard deviation of the percentage change in daily price. The implied volatility corresponds with the expectation of the market participants about the future volatility of the underlying which is reflected in the current option price.

The sensitivity of one variable to changes in another, e.g. the change in a bond's price with respect to changes in the redemption yield. In bond management the term is often interchangeable with modified duration.

A measure of the extent to which prices move. If the price of an underlying asset moves to a greater extent than before, its volatility is said to have increased and vice versa. So far as options are concerned, as volatility increases, the risk to the options writer also increases and the premium will rise.

This describes the fluctuations in the price of a stock or other type of security. If the price of a stock is capable of large swings, the stock has a high volatility. The pricing of options contracts depends in part on volatility. A stock with high volatility, for example, commands higher prices in the options market than one with low volatility. Volatility may be gauged by several measures, one of which involves calculating a security's standard deviation. Stock investors sometimes prefer to measure a stock's volatility versus that of an index, such as the Standard & Poor's 500 Index. This is known as a stock's beta. A beta of 1.2 implies a stock that is 20% more volatile than the S&P 500. When the S&P rises 10%, the stock is expected to rise 12%.

A measure of fluctuation in the market price of a security. A volatile stock or fund has frequent and large price swings. Statistically, the measure most commonly used for volatility is "standard deviation," the amount the price of a stock or mutual fund varies over time.

A measure of fair price movement from a STOC.

a measure of the variability of a market factor, most often the price of the underlying instrument. Volatility is defined mathematically as the annualised standard deviation of the natural log of the ratio of two successive prices. The actual volatility realised over a period of time (the historical volatility) can be calculated from recorded data. Volatility is one of the variables that must be specified in the Black-Scholes model of option pricing: a vanilla option will cost more when volatility is high than when it is low. However, volatility is the only one of these variables whose value must be estimated. The estimate used (known as the implied volatility) can be derived from the prices of options in the market and the known input variables. However, the Black-Scholes model also assumes that volatility is constant, which is not true. New techniques have been developed to cope with volatilityâ€(tm)s variability, including mean-reverting models (such as Garch) and stochastic volatility models.

The increase or decrease in an asset's price over time. High volatility means wide price changes that can occur in a relatively short period of time, while low volatility refers to smaller, or more gradual fluctuations.

The range and frequency of fluctuations in values such as share prices, exchange rates and interest rates. The higher the volatility, the less predictable the return.

This describes the fluctuations in the price of a stock or other type of security. If the price of a stock is capable of large swings, the stock has a high volatility. The pricing of options contracts depends in part on volatility. A stock with high volatility, for example, commands higher prices in the options market than one with low volatility. Volatility is measured by an alpha factor, for example, a stock with a 1.4 alpha is regarded as one whose price will rise by 40% in a year. Also: a measure of the volatility of a security relative to an entire market, such as the Standard & Poor's 500 Index, is known as the security's beta or beta coefficient.

The rise and fall price movement of a security. Securities that rise or fall rapidly within a short time frame are considered more volatile than those that donâ€™t. (See Beta)

The degree of fluctuation in the value of a security, mutual fund, or index, volatility is often expressed as a mathematical measure such as a standard deviation or beta. The greater a fund's volatility, the wider the fluctuations between its high and low prices.

A measure of the amount by which a currency s price is expected to fluctuate over a given period.

The variability of a portfolio's returns from one period to the next. Typically, a more volatile portfolio will decline more during bear markets and increase more during bull markets. Volatility is expressed mathematically by the standard deviation. Reducing portfolio volatility can be positive in two ways: 1) it makes the pain of a market decline less, and 2) it will actually cause wealth to grow faster than in a higher volatility portfolio with the same mean rate of return.

the tendency of financial markets to change abruptly at the whims of investors. As national control over financial markets fall as a result of capital account liberalization and the volume of portfolio investment skyrockets, volatility is increasing in financial markets. While unstable markets are profitable for speculators (see 'speculation'), the real economy can not function properly when exchange rates are fluctuating wildly and capital is flowing in and more often out, of a country in tidal waves.

One of the major factors in deciding an options worth. The degree to which the underlying price tends fluctuate over time. Historical volatility can be calculated by looking at price fluctuations over a specific period in the past. Implied volatility can be implied from option prices observed in the market place. This is achieved by using the Black-Scholes Equation, or one of its derivatives to calculate an option volatility which gives the current market option price. Historical and implied volatility can be used to estimate the price of OTC options.

Means risk, as measured by the standard deviation of a security's price.

Measure of the risk of an investment, fund or portfolio. In most cases, it is expressed as the annualised standard deviation of the changes in the value of the investment over time. A high (low) volatility indicates a high (low) investment risk. See "Risk".

In general, a measure of the uncertainty of the amount by which the price of the underlying instrument is expected to fluctuate in a given period of time. Generally expressed in annualized percentage terms as a standard deviation of the daily price changes in the underlying instrument.
