DUST is an aggressive inverse play on the widely followed gold mining index, the NYSE Arca Gold Miners Index. The fund promises to provide inverse exposure to these firms with a leverage factor of 2 on a daily basis. Like most leveraged and inverse products, it's designed to provide a one-day bet on the index. As such, the fund is designed to be held for no more than one trading day. For longer periods, the effects of compounding may cause it to sometimes drift from the -200% exposure it promises to provide to the underlying index. Since the fund is designed for daily use, the trading costs are of greater importance. Prior to March 31, 2020, the fund provided 3x inverse daily exposure to the same index.
