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.

Color (band)

Color (stylized as COLOR) was a Japanese punk band formed in 1985 by Dynamite Tommy, who founded the Free-Will record label a year later. They are considered to be important to the formation of visual kei. Their debut album Gekitotsu was named one of the top albums from 1989-1998 in a 2004 issue of the music magazine Band Yarouze.

History

Color released their debut album Gekitotsu, in January 1988. After releasing their second album Fools! Get Lucky!!, they signed to Crown Records and released their only major studio album a couple months later, Ask the Angels. It is said that the label made the band rewrite the album's lyrics, which were originally in English, in Japanese to be more accessible by the mainstream. It seemed to have worked, as Ask the Angels reached number 16 on the Oricon chart and their popularity increased. However, in January 1990 at a concert on the album's tour, in their hometown of Osaka, a fan was accidentally stomped to death. The band decided to lay low and avoid media, they ended up losing their contract with Crown. During this hiatus, Tommy formed Sister's No Future with Ken-chan (Kamaitachi), while Marry started Goatcore with You Adachi (Dead End).

Bass Armstrong (バース・アームストロング, Bāsu Āmusutorongu) is a retired professional wrestler and Tina's overprotective father. He is also the widower of Alicia Armstrong, who died of a disease when Tina was only six years old. He disapproves of Tina's aspirations of wanting to be a model (DOA2), a Hollywood actress (DOA3) and a rock star (DOA4). Consequently, he enters the DOA tournaments to put an end to her fame-seeking, only to fail at each attempt. In the fourth tournament, it is revealed that he intends to win so he would have enough money to enter the "Hyper Battle Grand Prix", which he then loses after seeing Tina's picture on a billboard and crashes into it after losing control of his bike. Like Tina in the English versions of the game, he, too, speaks with a Southern accent.
