EUM is the less aggressive of the funds providing inverse exposure to the MSCI Emerging Markets Index, offering -1x daily gearing. As such, it's worth noting that the index includes South Korea and Taiwan as an emerging market, which some other indices do not and which may change the type of exposure investors receive here. The fund, like its sibling fund EDZ, promises to provide its exposure on a daily basis. As such, it's not designed to be used as a long-term hedge against products but rather, to be used as a short-term trading vehicle. Those holding EUM for longer than a day must be prepared to rebalance their investment every day in order to avoid being taken for a ride by the mechanics of path dependency and decay. As a tactical short-term trading vehicle, trading costs weigh more impact than the expense ratio.
