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.

Vega (Street Fighter)

Vega, known in Japan as Balrog (バルログ, Barurogu), also known as Claw, is a fictional character from the Street Fighter fighting game series by Capcom. Vega is a mask-wearing, claw-wielding fighter from Spain who uses a personal fighting style combining Japanese ninjutsu, French savate, American Zipota and Spanish bullfighting, earning him the nickname of "Spanish Ninja".

Vega first appears in the original Street Fighter II in 1991 as the second of four boss opponents the player faces at the end of the single-player mode, a group known as the Four Devas or Grand Masters. From Street Fighter II: Champion Edition (the second version of the game) onwards, Vega and the other three boss characters, became playable. He reappears as a playable character in Street Fighter Alpha 3, Street Fighter EX2 and EX3, the Capcom vs. SNK series, SNK vs. Capcom: SVC Chaos, Street Fighter IV, Super Street Fighter IV, Street Fighter X Tekken and Street Fighter V.

Conception and creation

Vega was designed by Akira Yasuda with the premise of Street Fighter 1's Geki character in mind, and was initially conceived as a brief sketch of a masked man in a ripped shirt with long, frizzy hair. As development progressed the design evolved into a large, unarmed man, retaining the mask and dressed as a matador. The design was changed again, revolving around the concept of a foreign soldier with a cross on his vest and armed with a broadsword, while still retaining the mask. This design was eventually replaced in turn with another concept, a masked ninja in a bodysuit armed with a long metal claw on his right hand. Ultimately the character's finalized appearance was a culmination of all of these, incorporating various aspects of each into the finished design.

Ich Troje

Ich Troje ("The Three of Them") is a Polish pop band. Former members are Magdalena Pokora (aka Magda Femme, 1996–2000), Justyna Majkowska (2000–2003), Elli Mücke (2003) and Ania Wisniewska (2003–2010).

Ich Troje was founded in 1996 by songwriter Michał Wiśniewski and composer Jacek Łągwa.

Despite this, the group had five members when taking part in the Eurovision Song Contest 2006, with German rapper O-Jay (Olaf Jeglitza) as the fifth member.

Their music is castigated by critics, and Michal Wisniewski has said himself that he can't actually sing.

Nevertheless, since 2000, Ich Troje has been one of the most successful Polish groups. They have sold more than 1.5 million records since June 2001. For the past two years, Ich Troje have given over 300 concerts. Their songs are typically about love, betrayal and break-ups.

On 25 January 2003, Polish TV viewers chose Ich Troje to represent them in 2003 Eurovision Song Contest by televoting. They performed a song called Keine Grenzen-Żadnych granic, which was sung in three languages: (Polish, German, and Russian). The song finished seventh. A fully German version of the song was recorded as well.
