fair correlation priced in a correlation swap and the implied correlation of a dispersion trade. Indeed, a dispersion trade can be built upon variance or gamma swaps, hence creating an almost pure exposition to correlation, independent of the level of the stock. Furthermore, we will explain the observed spread between these two correlations in terms of the second-order derivatives of such dispersion trades. We Indeed, the implied correlation tends to be around 10 points higher. The purpose of this paper is to theoretically explain such a spread. In fact, we prove that the P&L of a dispersion trade is equal to the sum of the spread between implied and realised correlation - multiplied by an average variance of the components - and a volatility part. Basic Trade Idea. • Mechanics: a dispersion trade consists of – selling vol on the index, while simultaneously – buying vols on the component • Appeal: – historically index volatility has traded rich, while – individual stock volatility has been fairly priced – Îimplied correlation has historically been above realized. In finance, dispersion is used in studying the effects of investor and analyst beliefs on securities trading, and in the study of the variability of returns from a particular trading strategy or investment portfolio. It is often interpreted as a measure of the degree of uncertainty and, thus, risk,

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. Basic trade could be enhanced by buying options of firms with high belief disagreement (high analysts’ disagreement about firms’ earnings). Dispersion trading is a sort of correlation trading as the trades are usually profitable in a time when the individual stocks are not strongly correlated and the strategy loses money during stress periods when the correlation rises. The correlation among the securities are used as a factor to determine the entry of a trade. In finance, correlation trading is a strategy in which the investor gets exposure to the average correlation of an index. The key to correlation trading is being able to predict when future realized correlation amongst the stocks of a particular index will be greater or less than the "implied" correlation level derived from derivatives on the index and its single stocks. Correlation is involved in dispersion trading in two ways: Firstly because trades can be more profitable when component stocks are not highly correlated. Secondly, part of the formula for calculating a dispersion trading strategy involves working out the implied correlation of an index, also known as the ‘dirty correlation’.
To be specific, dispersion trading capitalizes on overpricing of index options in relation to individual options when the correlation is high. Depending on the value of correlation between individual stocks, the dispersion can be traded by selling the index options and buying options on index components or by buying index options and selling options on index components.
