Gold has enjoyed greater demand in a low interest-rate environment as the hard asset becomes more attractive to investors compared to yield-bearing assets. However, traders lose interest in gold when rates rise since the bullion does not produce a yield. Interest rates remain low in many developed markets and some emerging markets have been rapidly lowering borrowing costs this year.

GDX has lost $2.4 billion in assets this year, a total surpassed by just one other ETF. Conversely, investors have added $1.1 billion to GDXJ.

Popular leveraged gold miners ETFs include the Direxion Daily Junior Gold Miners Index Bull 3x Shares (NYSEArca: JNUG), the triple-leveraged answer to the popular GDXJ. The Direxion Daily Gold Miners Bull 3X Shares (NYSEArca: NUGT) is JNUG’s large-cap counterpart.
