Dispersion trading and volatility gamma risk
Dispersion Trading is a trading strategy used widely in developed markets. The main focus of this strategy is to trade the dispersion of an index versus all its compo-nents. This study presents a case of study for the Brazilian Market and shows how the dispersion trading can be implemented for the local market. This papers studies an options trading strategy known as dispersion strategy to investigate the apparent risk premium for bearing correlation risk in the options market. Previous studies have attributed the profits to dispersion trading to the correlation risk premium embedded in index options. Dispersion trading is a complex strategy, however this is rewarded with the strategy being a profitable one which offers high rewards in response to a low risk. To make this strategy even better, it would be necessary to automate the strategy and the hedging should be dynamic as per the price movements. Once upon a time dispersion trading desks used to be the kings (and queens) of volatility trading in the equity arena (if we ignore the 35 mio USD short vega position by LTCM). Dispersion desks can handle significant volatility risks in the same way that a basket desk can handle extremely large deltas per instrument or a cap/floor vs. swaption trader can handle extremely large volatility risks per underlying. A dispersion trade also gives an exposure to the implied correlation of the market, since as aforementioned, a good proxy for it is the square of the ratio between the implied index volatility and the average of the equity components implied volatilities. Delta is a measure of the change in an option's price or premium resulting from a change in the underlying asset. Gamma measures Delta's rate of change over time as well as the rate of change in the underlying asset. Gamma helps forecast price moves in the underlying asset.

The volatility gamma of a dispersion trade depends on the level of correlation and volatility (similarly to a straddle gamma depending on volatility and spot). However, volatility gamma also depends on the average level of single-stock volatility (single- stock volatility defines the relationship between index volatility and correlation – see Appendix II). The dispersion trading uses the known fact that the difference between implied and realized volatility is greater between index options than between individual stock options. The investor, therefore, could sell options on index and buy individual stocks options.

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, When implied volatility on a stock is low, the gamma of at-the-money options will be high, while the gamma of deep out-of-the-money options will be near zero. This is because, when volatility is low, deep out-of-the-money options will have very little value as the time premium is so low.
