PPLT tracks the spot price of platinum with its physically held platinum bars, located in JPMorgan vaults in London and Zurich. The underlying metal is priced off the London Platinum and Palladium specifications for good delivery, so expect a close relationship with spot prices. PALL is structured as a grantor trust preventing trustees from lending the underlying metal. On April 27, 2018, Aberdeen purchased the fund from issuer, ETF Securities.
