The EURO STOXX 50 Futures Roll Index replicates a hypothetical portfolio of a series of long position EURO STOXX 50 futures contracts traded on Eurex. The portfolio is invested into the first nearby futures contract and then rolled into the next nearby contract over the four days preceding the expiry date of the futures contracts series, which is the third Friday in March, June, September and December. The roll period works as follows: until the Monday preceding the third Friday of a roll month, all of the index value is allocated to the first nearby futures contract. Starting Monday night, on a daily basis for four days, one fourth of the index value is shifted into the next nearby contract. With the open of trading on Friday morning, the roll is complete and all index value is allocated to the next nearby contract.
