The greeks of exotic derivatives– such as exotic options, exotic swaps, etc. Greexotics (or exotic greeks) measure the sensitivity of exotic derivatives to changes in market rates or prices, which in turn help determine its final outcomes (payoff or net profit/ loss). Examples of exotic greeks are exotic vanna, exotic volga, alpha (= gamma / theta), DeltaVega, DeltaTheta, GammaVega, GammaTheta, etc.
An exotic derivative is more complex than vanilla derivatives (examples of vanilla derivatives include vanilla options, vanilla swaps, etc.) in terms of determination of payoff. Exotic derivatives are riskier than vanilla or standard derivatives, but nevertheless provide flexibility as to ability to address specific hedging needs and regulatory requirements, among others. Therefore, calculation of exotic greeks requires more sophisticated and tailor-made tools and formulae.
