Solo una aclaración. Estos dos activos no son ETFs (exchange-traded funds) sino ETCs (exchange-traded commodities) que por lo general tienen un riesgo extra.
Con un ejemplo se entiende mejor:
iShares Gold Trust (IAU) is a type of ETF that buys physical gold in exchange for shares issued. The buyer of the ETF, therefore, owns a fractional piece of the gold held in trust.
With iShares Physical Gold ETC (SGLN), investors don’t own a piece of the gold they are investing in. Rather, the underwriters of the fund financially back the note (the ETC) with the holdings.
An ETC is a note or debt instrument which is underwritten by a bank for the issuer of the ETC.
