EJAN uses options in an effort to moderate losses on iShares MSCI EM ETF (EEM) over a one-year period starting each January. The fund foregoes some upside return as well as the dividend component of the index, because the options are written on the price (not total) return version of the index. In exchange for preventing realization of the first 15% of EEM losses, investors forego upside participation above a certain threshold, which is reset annually.
