YCS offers 2x leveraged inverse exposure to the Japanese yen/US dollar cross, providing big gains when the yen falls against the dollar. The fund is designed to be a short-term product, and rebalances its -2x exposure on a daily basis. As a result, long-term returns in YCL could diverge significantly from expected returns due to compounding effect and path dependency. Also, keep in mind that the fund's NAV is calculated according to the JPY/USD cross as published in the Wall Street Journal a value that may differ from other quoting sources.
