Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Shrug

A shrug is a gesture that is performed by lifting both shoulders up, and is a representation of an individual either not knowing an answer to a question, or not caring about a result. It is an emblem, meaning that it integrates the vocabulary of only certain cultures and may be used in place of words. It can also be used when someone is simply ignoring the person's question. It may be accentuated with raised eyebrows, a turned-down mouth and/or an exaggerated frown, and can be accompanied by raised palms. It is very common in Western culture, rather than saying "I don't know", they would simply perform a shrug. In the English-speaking world it may be accompanied by a three syllable grunt or hummed mumble mimicking the intonation of "I dunno".

A specific rendezvous of chronic shoulder shrugs, also misconceived, are the symptomatic tics of Tourettes syndrome. Shrugging by coping with indifference and indecision, psychotherapeutic or psychoanalytic the effectuated unconditional aspect can indicate anxiety and numerous psychological disorders: a solute example is schizoid personality disorder.

Shrug (clothing)

A shrug is a cropped, cardigan-like garment with short or long sleeves, typically knitted, usually for women. Generally, a shrug covers less of the body than a vest would, but it is more tailored than a shawl. Shrugs are typically worn as the outermost layer of an outfit, with a full shirt, tank top, or dress beneath.

A shrug covers a small portion of the upper body. Some shrugs are tied together just below the bustline. Another style is cut off at the sides and thus little more than a pair of sleeves joined at the back.

A bolero jacket or bolero (pronounced /bollero/) is a more formal garment of similar construction but made of stiffer fabric, essentially a short tailored jacket, inspired by the matador's chaquetilla. Like the shrug, the sides of the bolero only meet at one point.
