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.

Prayers (rock duo)

Prayers is an electronic rock duo founded in 2013 by Rafael Reyes and Dave Parley. Prayers are the first musicians/artists use the term Cholo goth to define their genre of music which lyrically explores the harsh realities of gang and street life over throbbing beats and swirling synthesizers.

Prayers is influenced by Christian Death, Depeche Mode, Bauhaus, Pet Shop Boys and other Gothic rock and dark 80s music, as well as by Reyes' life as gang member in the Sherman Grant Hill Park 27 gang, one of San Diego's oldest gangs, also known as Sherman 27. He was jumped into the gang as a teenager. Prayers' music, lyrics and image breaks down stereotypes within the Goth and Cholo subcultures.

Prior to forming Prayers, Reyes, who was born Cotija, Michoacán and came San Diego as young child, had created two other bands, Baptism of Thieves and Vampire, and performed in a solo project, Nite Ritual. Reyes and Parley, a Tijuana native, began recording immediately upon meeting. In three days they had recorded their first CD, SD KILLWAVE which they released independently on first as a CD and download and then on vinyl.

She tells MTV News, "I literally got my head split open during the shoot. I have a big scar across my face. The [camera] dolly came a little close, and I was headbanging, and we just collided and my whole face split open. There was blood all over the place." The band's management tried to call off the shoot but Brink insisted they finish the filming of the video.
