The high difference between implied volatility of index options and subsequent realized volatility is a known fact. Trades routinely exploit this difference by selling options with consecutive delta hedging. There is however more elegant way to exploit this risk premium - the dispersion trading. The dispersion trading uses known fact that difference between implied and realized volatility is greater between index options than between individual stock option. Investor therefore could sell options on index and buy individual stocks options. 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 losses 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. Motivated by extensive evidence that stock-return correlations are stochastic, we analyze whether the risk of correlation changes affecting diversification benefits may be priced. We propose a direct and intuitive test by comparing option-implied correlations between stock returns obtained by combining index option prices with prices of options on all index components with realized correlations. Our parsimonious model shows that the substantial gap between average implied Empirical implementation of our model also indicates that the index variance risk premium can be attributed to the high price of correlation risk. Finally, we strategies evidence that option-implied correlations have remarkable predictive power for future stock market returns, which also stays significant after controlling for a number of fundamental market return predictors. There has been an increasing variety of volatility related trading strategies developed since the publication of Black-Scholes-Merton study. In this paper we study one of dispersion trading strategies, which attempts to profit from mispricing of the implied volatility of the index compared to implied volatilities of its individual constituents. Although the primary goal of this study is to find whether there were any profitable trading opportunities from November 3, through May 10, in the German option market, it is also interesting to check whether broadly documented stylized fact that implied volatility of the index on average tends to be larger than theoretical volatility of the index calculated using implied volatilities of its components Driessen, Maenhout and Vilkov and others still holds in times of extreme volatility and correlation that we could observe in the study period. Also we touch the issue of what is or was causing this discrepancy. This thesis tries to explore the profitability of the dispersion trading strategies. We begin examining the different methods proposed to price variance swaps. We have developed a model that explains why the dispersion trading arises and what the main drivers are. After a description of our model, we implement a dispersion trading in the EuroStoxx We analyze the profile of a systematic short strategy of a variance swap on this index while being long the constituents. We show that there is sense in selling correlation on short-term. We also discuss the timing of the strategy and future developments and improvements. After the two years of studies in the dispersion of mathematical finance at Univ ersity of Paris 1, I had a chance to work with an asset management team as a quantitative analyst at Lyxor Asset Management, Societe Generale in Paris, France. My first task was to develop an analysis of the performances of the funds on hidden assets where the team's main focus was on, such as Volatility Swap, Variance Swap, Correlation Swap, Covariance Swap, Absolute Dispersion, Call on Absolute Dispersion Palladium. The purpose was to anticipate the profit and to know when and how to reallocate assets according to the market conditions. In particular, I have automated the analysis through Dispersion in Excel. Secondly, I had a research project on Correlation trades especially involving Correlation Swaps and Dispersion Trades. This report is to summarize the research I have conducted in this subject. Lyxor has been benefiting from taking short positions on Dispersion Trades through variance swaps, thanks to the fact that empirically the index variance trades rich with respect to the variance of the components. However, a short position on a dispersion trade being equivalent to taking a long position in correlation, in case of a market crash or a volatility spikewe can have a loss in the position. Thus, the goal of the research was to find an effective hedging strategy that can protect the fund under unfavorable market conditions. The main idea was to apply the fact that dispersion trades and correlation swaps are both ways to have exposure on correlation, but with different risk factors. While correlation swap has a pure exposure to correlation, dispersion trade has exposure to the realised volatilities as well as the correlation of the components. Thus, having risk to another factor, the implied correlation of a dispersion trade is above empirically, 10 points the strike of the equivalent correlation swap. Thus, taking these two products and taking opposite positions in the two, we try to achieve a hedging effect. Moreover, I trading how this strategy would have performed in past market conditions back-test and under extremely bearish market conditions stress-test. As the recent financial crisis has shown, diversification benefits can suddenly evaporate when correlations unexpectedly increase. An analysis of unconditional and conditional correlation hedging strategies shows that only some conditional correlation hedging strategies add value. A dispersion trade is entered into when a trader believes that the constituents of an index will be more volatile than the index itself. The South African derivatives market is fairly advanced, however it still experiences inefficiencies and dispersion trades have been known to perform well in strategies markets. This paper tests the South African market for dispersion opportunities and explores various methods of executing these trades. The South African market shows positive results for dispersion trading; namely short-term reverse dispersion trading. Call options and Cross-Sectional Volatility CSV swaps are also tested. CSV swaps performed poorly whereas call options experienced annual returns well above the market. Dispersion trading is a strategy involving the selling of options on an index against buying a basket of options on individual stocks. Such a strategy is a play on the behaviour of correlations during normal markets and during large market moves. If the individual assets returns are widely dispersed then there may be little movement in the index. This would result in a large payoff on the individual asset options but little to pay back on the short [[index] option. The volatility on an index. If you know the implied volatilities for the individual stocks and for the index option then you can back out an implied correlation. Dispersion trading can be interpreted as a view on this implied correlation versus one's own forecast of where this correlation ought to be, perhaps based on historical analysis.

Similar Publications Electronic copy available at: Master of Mathematical Finance 1 Introduction In the early s some sophisticated equity derivatives traders started to make profits from price differences in volatility markets by selling options on an index and simultaneously buying options on the constituent stocks. Such a strategy bets on the degree to which constituent stocks disperse, leading to the name dispersion trading. Since such strategies were difficult to hedge on one hand and costly to implement on the other, only few traders performed these trades. Due to increased liquidity in option markets and the development of volatil - ity derivatives, the access to dispersion trading is more commonly available today. This gives investors access to a further dimension of investment strategies hopefully increasing the benefits of diversifica - tion. Among these products are funds employing strategies denoted market-neutral or relative-value since they do not replicate a certain equity market but are aimed at taking advantage of its inefficiencies. Dispersion trading, formerly also known as index-option arbitrage, strategies one such strategy and thereby received more and more attention. What is dispersion trading exactly? The term dispersion trading comprises a multitude of different trading strategies and there is no clear-cut definition of a dispersion trade since the way of implementing such a strategy has evolved trading time and the products utilized have changed. However, the strategies have in com - mon that they trade index volatility against the volatility of the index constituents with the objective of exploiting price differences in index and single-stock volatility markets. Historically, a long dispersion position, i. With volatility becoming a common investment vehicle, various products for trading index and single-stock volatilities are established today. Therefore, definitions of volatility and correlation are presented and their modeling and predictability are discussed extensively. In particular, we rig - orously investigate different measures of average correlation of an index. Thereby we set the foundations for academically discussing dispersion trading. Using the concept of average correlation we rationalize that the potential profit obtained in a dispersion trade can be attributed to particular properties of the index volatility skew and to a negative premium for correlation risk. We confirm these results and recent empirical findings by examining the average correlation of the Dow Jones Euro Stoxx Another major goal is the comparison and evaluation of different dispersion trad - ing strategies. We characterize various ways to set up dispersion trades and discuss their properties and their practicability. To evaluate the theoretical findings, we test several strategies empirically and evaluate their performance in stress scenarios. Fi - nally, the use of dispersion trading in a portfolio context is discussed.
