GDXD is a note that provides 300% daily inverse leveraged exposure. As such, it is not a buy-and-hold product, and is best designed for short-term tactical trading purposes only. Returns can vary significantly from -3x exposure to its underlying index if held for longer than a day. GDXD`s underlying index, the S-Network MicroSectors Gold Miners Index, is comprised of two established ETFs, namely: VanEck Gold Miners ETF (GDX) and VanEck Junior Gold Miners ETF (GDXJ), which primarily invest in the global gold mining industry. Both ETFs select and weight its constituents by market cap. Knowledge of the benefits and risks is paramount before investing in this product.
