Weather Derivative
Weather derivatives are financial instruments that can be used by organizations or individuals as part of a risk management strategy to reduce risk associated with adverse or unexpected weather conditions. Weather derivatives are index-based instruments that usually use observed weather data at a weather station to create an index on which a payout can be based. This index could be total rainfall over a relevant period—which may be of relevance for a hydro-generation business—or the number where the minimum temperature falls below zero which might be relevant for a farmer protecting against frost damage. As is the case with parametric weather insurance, there is no proof of loss provision. Unlike "indemnity" insurance-based cover, there is no need to demonstrate that a loss has been suffered, however an indemnity insurance policy for weather is a rarely utilized instrument. Settlement is objective, based on the final value of the chosen weather index over the chosen period. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Financial Instrument
Financial instruments are monetary contracts between parties. They can be created, traded, modified and settled. They can be cash (currency), evidence of an ownership interest in an entity or a contractual right to receive or deliver in the form of currency (forex); debt ( bonds, loans); equity ( shares); or derivatives ( options, futures, forwards). International Accounting Standards IAS 32 and 39 define a financial instrument as "any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity". Financial instruments may be categorized by "asset class" depending on whether they are equity-based (reflecting ownership of the issuing entity) or debt-based (reflecting a loan the investor has made to the issuing entity). If the instrument is debt it can be further categorized into short-term (less than one year) or long-term. Foreign exchange instruments and transactions are neither debt- nor equity-based and bel ...

CME Hurricane Index
The Chicago Mercantile Exchange Hurricane Index (CMEHI) is an index which describes the potential for damage from an Atlantic hurricane in the United States. The CMEHI is used as the basis for trading hurricane futures and options on the Chicago Mercantile Exchange (CME). It is very similar to the Hurricane Severity Index, which also factors both size and intensity of a hurricane. Index calculation The CMEHI takes as input two variables: the maximum sustained wind speed of a hurricane in miles per hour and the radius to hurricane-force winds of a hurricane in miles (i.e. how far from the center of the hurricane winds of 74 mph or greater are experienced). If the maximum sustained wind speed is denoted by ''V'' and the radius to hurricane-force winds is denoted by ''R'' then the CMEHI is calculated as follows: : \text = \left ( \frac \right )^3 + \frac\left ( \frac \right ) \left ( \frac \right )^2 where the subscript ''0'' denotes reference values. For use on the CME, the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fourier Transform
A Fourier transform (FT) is a mathematical transform that decomposes functions into frequency components, which are represented by the output of the transform as a function of frequency. Most commonly functions of time or space are transformed, which will output a function depending on temporal frequency or spatial frequency respectively. That process is also called ''analysis''. An example application would be decomposing the waveform of a musical chord into terms of the intensity of its constituent pitches. The term ''Fourier transform'' refers to both the frequency domain representation and the mathematical operation that associates the frequency domain representation to a function of space or time. The Fourier transform of a function is a complex-valued function representing the complex sinusoids that comprise the original function. For each frequency, the magnitude (absolute value) of the complex value represents the amplitude of a constituent complex sinusoid with that ...

Autoregressive Moving Average Model
In statistics, econometrics and signal processing, an autoregressive (AR) model is a representation of a type of random process; as such, it is used to describe certain time-varying processes in nature, economics, etc. The autoregressive model specifies that the output variable depends linearly on its own previous values and on a stochastic term (an imperfectly predictable term); thus the model is in the form of a stochastic difference equation (or recurrence relation which should not be confused with differential equation). Together with the moving-average (MA) model, it is a special case and key component of the more general autoregressive–moving-average (ARMA) and autoregressive integrated moving average (ARIMA) models of time series, which have a more complicated stochastic structure; it is also a special case of the vector autoregressive model (VAR), which consists of a system of more than one interlocking stochastic difference equation in more than one evolving random vari ...
