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).

Burner (rocket stage)

The Burner and Burner 2 rocket stages have been used as upper stages of launch vehicles such as the Thor-Burner and Delta since 1965. The currently available Burner 2 is powered by a Star 37 solid rocket motor. Thor Altair and Thor Burner were mainly used for US military meteorological programs (DMSP), although they also launched technological satellites.

In addition to use on Delta family rockets, Burner 2 stages have been used on both Atlas and Titan rockets.

Burner 1

The Burner 1 stage was based on the Allegany Ballistics Laboratory (ABL) X-248 Altair rocket stage used for the third stage of some Vanguard launch vehicles. For the Burner designation, Boeing equipped the stage with 3-axis control. The solid rocket engine later designated Thiokol FW-4 (TE 364-1). The first Thor Burner launch occurred on January 19, 1965 for the US military meteorological program DMSP B4A-01 satellite (first Block 4A).

Burner 2 or Burner II

In March 1964, the Defense Meteorological Satellite Program (DMSP) office approved plans to develop a more powerful Thor Burner 2 launch vehicle. The Burner 2 was developed for the Air Force Space Systems Division in 1965. The Boeing Company served as prime contractor with major subcontractors: Thiokol Chemical Corporation (solid rocket motor); Honeywell Inc. (pre-programmed inertial guidance system); Walter Kidde Co. (reaction control system).
Burner 2 featured a Thiokol Star-37B motor (TE-M-364-2) which was derived from the Surveyor lunar retro-rocket. The first Thor Burner 2 launch occurred on September 16, 1966 for the US military meteorological program DMSP B4A-07 satellite

Burning Man

Burning Man is an annual gathering that takes place at Black Rock City—a temporary community erected in the Black Rock Desert in Nevada. The event is described as an experiment in community and art, influenced by 10 main principles, including "radical" inclusion, self-reliance and self-expression, as well as community cooperation, gifting and decommodification, and leaving no trace. First held in 1986 on Baker Beach in San Francisco as a small function organized by Larry Harvey and a group of friends, it has since been held annually, spanning from the last Sunday in August to the first Monday in September (the U.S. Labor Day); for example, Burning Man 2015 took place August 30 – September 7, 2015.

At Burning Man the community explores various forms of artistic self-expression, created in celebration for the pleasure of all participants. Participation is a key precept for the community – selfless giving of one's unique talents for the enjoyment of all is encouraged and actively reinforced. Some of these generous out-pourings of creativity can include experimental and interactive sculpture, building, performance, and art cars among other mediums, often inspired by the yearly theme, chosen by organizers. The event takes its name from its culmination, the symbollic, ritual burning of a large wooden effigy ("the Man") that traditionally occurs on the Saturday evening of the event.
