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.

    Mr. Lil One - Karma Lyrics
    (Mr. Lil One)
    Where's my G's at sippin Mickey's and wearing Dickies
    Throwin up your set with a neck full of hickies
    No I'm not Ricky but I live la vida loca
    Buckin down you socas that be talkin out your bocas
    Mota for the smokers, coka for the nose
    Peace to all my niggas that be talkin shit to hoes
    Clothes always creased screamin out f**k peace
    Nigga I'm from the streets where the devil never sleeps
    Deep into the bangin started slangin tryin to make it
    Run up on my shit, you got to murder me to take it
    Never tried to fake, tried to make it the way I can
    Cause man made the money, money never made the man
    Listen to the whistle, keep your fingers on the pistol
    F**kin wit that crystal makes a mothaf**ka dismissed
    Every thing you love, and every thing done
    Don't mean a f**kin thing when a mothaf**kas sprung
    (Chorus)
    Leave it alone you're f**kin up holmes
    You're doin em wrong, You're doin em wrong
    You're doin em wrong, for all the wrong reasons
    You got a Karma with all the four seasons
    (2x)
    (Mr. Lil One)
    Any ways, just another day but I'm livin
    Givin it all I got for my mothaf**kin Tot
    Hustlin my shit makin sure it's in your spot
    Bumpin down your block hear it every where you walk
    Hocus Pokus I was faded when I wrote this
    PCP smokers bangin who the lokest
    Bury you, I'm darin you, see if I put scare in you
    No air in you, left, when I done leave you hung
    Tattos and hair nets, youngsters and vets
    Throwin up their sets screamin out f**ked the rest
    Let the dogs loose, gettin faded off the juice
    I'm fightin to get rich while you're fightin over a bitch
    Mothaf**k you both, I'm stickin to my oath
    Terrorfy you bitches when you hear about my riches
    It's not about my salary it's all about reality
    I'm tryin to feed my family so why f**k you mad at me
    (Chorus)
    (Mr. Lil One(Talkin))
    Yeah, this is to all you back stabbing bitches
    All you two faced hipocrits
    You mothaf**kin haters out there
    You know who you are
    You got some karma for that ass
    Karma for all the four seasons
