A basket option is an option on a portfolio of underlying assets, and the option price is highly dependent on the correlations between the underlying assets. Sec.3 is devoted to the option with stochastic correlation coefficient and volatility. Basket Option Pricing and Implied Correlation in a One-Factor Lévy Model 337 processes like VG, NIG, Meixner, etc. In equity derivatives, they are structured as follows: Long Vanilla Dispersion ≡ Long Basket Straddle and Short Single-Stock Straddles The long basket straddle leg is, broadly speaking, long volatility and long correlation; in contrast, the short single-stock straddles leg is short volatility and correlation-neutral. Grasselli and Tebaldi [19] and others proposed stochastic correlation models for option pricing. An example of such a derivative is a basket option. Dispersion trading is a sort of correlation trading as trades are usually profitable in a time when the individual stocks are not strongly correlated and loses money during stress periods when correlation rises.

Dufresne (2000) uses a Laguerre series to approximate Asian option prices, but his method fares poorly for short maturity options. For the approximate basket we determine the underlying characteristic function and hence we can derive the related basket option prices by using the Carr–Madan formula. The investor, therefore, could sell options on index and buy individual stocks options. The technique attempts to overcome some of the like basket options. of correlation coefficients and a partial differential equation for quanto op-tions is derived. 2.2. Keywords: Wishart processes, Best-of Basket option, Stochastic Correla-tion, FFT. A trader could therefore sell optionson index and buy individual stock options or vice versa based on this volatility difference. We prove existence and uniqueness of solutions for the model stochastic differential equations, provide formulas for a number of basket options, and analyze the dependence structure of the model in detail by deriving a number of results on covariances, its copula function and rank correlation measures and volatilities-assets correlations. Usual business practice when dealing with rainbow options is to take constant correlation coefficients - and this despite empirical analyses unambiguously showing An increase in correlation implies an increase in the overall basket volatility. Best-Of call options are costlier than a basket call option on the same underlying assets. Spread options are very common in energy markets, they … As a result, this new one-factor Lévy model is more flexible and can capture other types of dependence. The second and third ingredients, the correlation matrix and the copula method, are used in order to generate the value of the basket option using Monte Carlo simulations. Basket options are derivatives that belong to the class of products that are subject to nonlinear and correlation risk. An additional difficulty in evaluating basket options is due to the correlation structure involved in the basket, which is observed to be volatile over time as is the volatility. The numerical price for stochastic correlation is compared with the one for constant correlation. As a result they are not as popular as the Worst-Of call options. The ultimate objective of this example is to compare basket option prices derived from different noise processes. However generating and using independent random paths for each asset will result in simulation paths that do not reflect how the assets in … The authors of [19] argue that their model generates implied correlation skew for the "best-of" basket option. Implied correlation is a measure on how index volatility compares to the volatility of a basket of the individual index components. Di… Basket options are fundamentally different from a collection of options on individual assets comprising the basket, as they are the so-called correlation, or cross-commodity derivatives that allow to manage the correlation risk. The first noise process is a traditional Brownian motion model whose index portfolio price process is driven by correlated Gaussian random draws. This approach of viewing Correlation Vega as the sensitivity of the basket volatility with respect to the correlation between the underlying assets stems from the approach that many traders in the good old days would try to reduce a complex product to a "pseudo-vanilla" option.
