PLTM invests directly in physical platinum stored in a London vault and custodied by ICBC Standard Bank. The structure of a grantor trust protects investors since trustees cannot lend the platinum bars. Since PLTM holds physical platinum bars, investors can expect the fund to track the price of spot platinum closely. Moreover, the fund provides exposure that is essentially identical to established competitors such as PPLT. Like all physically held precious metals funds, any long-term gains will result in noteworthy tax liabilities, since PLTM is considered a collectible. NAV is determined using the LBMA Platinum Price PM, so expect a close relationship with spot prices.
