Over the past three months, the Aberdeen Standard Platinum Shares ETF (NYSEArca: PPLT) has increased 43.1%% and the GraniteShares Platinum Trust (PLTM) has added 44.5%. Money managers have started pouring into platinum partly because the hard asset is seen as a good store of value in face of potentially rising inflation pressures, the Wall Street Journal reports. Platinum initially gained momentum on the improving industrial consumption of the precious metal, notably in automobile catalytic converters that limit harmful greenhouse gases from exhaust fumes.
