The investment objective of the fund is to track both the upward and the downward evolution of the S&P 500® Net Total Return (the "Index") denominated in US Dollars - while minimising the volatility of the difference between the return of the Sub-Fund and the return of the Index (the “Tracking Error”). For daily hedged share classes, the Sub-Fund will also use a daily currency-hedge strategy, in order to minimize the impact of the evolution of each respective share class currency against currencies of each Index component.
