The EURO STOXX 50 Protective Put 80% 18m 6/3 index aims to replicate a combined investment in the EURO STOXX 50 index and a long position in a put option on the same index. The investment objective of the replicated strategy is to profit from the appreciation of the EURO STOXX 50, while simultaneously limit the losses in falling markets through the put option. The put option is rolled quarterly in March, June, September and December. On each roll date, the existing option is sold and replaced by a new one with 80% strike. Additionally, the options purchased in June and December will mature in 18 months, while those purchased in March and September in 15 months (i.e., they keep the same maturity of the existing option).
