The nearest 3 OTM strikes are considered in this project. It involves a short options positions on an index and a long options positions on the components of the index or vice versa. That is as described in one of the other answers. The flip side for him is that he is short gamma and this can be a losing situation if the underlying moves.

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.

The dispersion trading uses the fact that the difference between implied and realized volatility is greater between index options than between individual stock options. A trader could therefore sell options on index and buy individual stock options or vice versa based on this volatility difference.
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. Depending on the value of correlation between individual stocks, dispersion can be traded by selling the index options and buying options on index components or by buying index options and selling options on the index components.
The most well-received theory for the profitability of this strategy is market inefficiency which states that supply and demand in the options market drives premiums which deviate from their theoretical value. To distinguish dispersion trading, it is simply a hedged strategy which takes advantage of relative value differences in the implied volatilities between an index and index component stocks.
In equilibrium, this different exposure to disagreement risk is compensated in the cross-section of options and model-implied trading strategies exploiting differences in disagreement earn substantial excess returns.
Sorting stocks based on differences in beliefs, we find that volatility trading strategies exploiting different exposures to disagreement risk in the cross-section of options earn high Sharpe ratios. The results are robust to different standard control variables and transaction costs and are not subsumed by other theories explaining the volatility risk premia. 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 provide 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.
Dispersion Trading in German Option Market http: 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. Studying the properties of the correlation trades http: 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. 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. Submit any pending changes before refreshing this page.

There are two main option traders in the market: Directional Traders bet on stock direction before the contract expiration. For example, traders buy straddle or strangle in anticipation of a big one-directional move.
Volatility Traders trade volatility through delta hedging. Delta hedging means hedging options with stock buy call, sell stock to eliminate stock movement as a factor in overall PNL: Investors put premium on puts to protect against downside move. Sell calendar long gamma and short vega when the term structure is steep: Investors generally put premium in back months and you anticipate the term structure to flatten after correction.
As Alex has already mentioned Sell gamma, although this is often considered very risky as you collect little theta and lose BIG short gamma. An example would be if you offer a 1 to for the Cubs to win the worlds series. Bet on dividend and interest rate based on put-call parity 5.

Out-of-the-money options at expiration are worthless, but before expiry they can have value because they may have a chance of expiring in-the-money. But as time passes, this optionality has to evaporate. So if one owns a bunch of out-of-the-money options, one can expect to see their value erode over time, other things being equal. The flip side to this loss of value through time decay is that by being long such options, one is long gamma.
If a trader owns options, they can lose value gradually simply by time passing. But the trader can make a profit from owning these options by gamma hedging. Similarly, if a trader is short options, he can collect money as time passes, because the options he is short can diminish in value. The flip side for him is that he is short gamma and this can be a losing situation if the underlying moves.
What is 'Dispersion'
Dispersion trading is a very profitable strategy which offers high rewards in response to a low risk, but it is essential to implement the strategy correctly to gain the profit. The Dispersion Trading is a strategy used to exploit the difference between implied correlation and its subsequent realized correlation. The dispersion trading uses the fact that the difference between implied and realized volatility is greater between index options than between individual stock options. Volatility dispersion trading is a popular hedged strategy designed to take advantage of relative value differences in implied volatilities between an index and a basket of component stocks, looking for a high degree of dispersion.
