The EURO STOXX 50 Realized Dispersion Index measures the difference between the market-cap weighted sum of the index constituents’ absolute returns and the absolute index return. The index is reset annually.
Absolute returns serve as a measure for daily realized volatility and the index represents a long position in a series of at-the-money straddles with one day to maturity on the components of the EURO STOXX 50 Index and a short position in at-the-money straddles on the EURO STOXX 50 Index. At-the-money straddles are traditionally used to trade volatility.
