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.

Cupid

In classical mythology, Cupid (Latin Cupido, meaning "desire") is the god of desire, erotic love, attraction and affection. He is often portrayed as the son of the love goddess Venus and the war god Mars, and is known in Latin also as Amor ("Love"). His Greek counterpart is Eros.

Although Eros appears in Classical Greek art as a slender winged youth, during the Hellenistic period, he was increasingly portrayed as a chubby boy. During this time, his iconography acquired the bow and arrow that represent his source of power: a person, or even a deity, who is shot by Cupid's arrow is filled with uncontrollable desire. In myths, Cupid is a minor character who serves mostly to set the plot in motion. He is a main character only in the tale of Cupid and Psyche, when wounded by his own weapons he experiences the ordeal of love. Although other extended stories are not told about him, his tradition is rich in poetic themes and visual scenarios, such as "Love conquers all" and the retaliatory punishment or torture of Cupid.

Cupid (1998 TV series)

Cupid is a 1998–1999 American comedy-drama series created by Rob Thomas, which featured Paula Marshall as Dr. Claire Allen, a Chicago psychologist who is given charge of a man named Trevor Hale (Jeremy Piven). Hale believes he is Cupid, sent down from Mt. Olympus by Zeus to connect 100 couples without his powers, as a punishment for his arrogance.

Originally broadcast on ABC on Saturday evenings at 10 p.m. EST, the show lasted one season.

Plot

Trevor Hale is attractive, witty, uncommonly intelligent—and he may be Cupid, the Greco-Roman god of erotic love. Probably not, but he thinks so. Trevor's insistence that he is Cupid lands him in a mental hospital, where he meets psychologist Claire Allen, a renowned authority on romance. Trevor tells Claire that he has been stripped of his godly powers by Zeus, and exiled from Mount Olympus as a punishment for arrogance. To win his way back among the gods, Trevor must unite 100 couples in everlasting love, without his bow and arrows. Claire does not believe in Cupid, but she risks her career by releasing Trevor from the hospital, assuming responsibility for his behavior. Trevor finds work as a bartender, and regularly disrupts Claire's group therapy sessions. All the while, he plots his campaign to promote romance, and earn his way back to Olympus. While encouraging sexual abandon in others, Trevor remains celibate; he believes sex with a mortal will confine him to Earth forever.
