...buy the miners, not the metals themselves. Platinum is an industrial metal as is palladium and their demand is primarily in the automotive industry. They may be good investments, such as many of the other commodities have been, but they don't serve the same role as financial backstop the way that gold and silver do.
A great way to do this is through Vanguard's Precious Metals and Mining fund (VGPMX) which invests in gold, silver, platinum, palladium, rare earth, and diamond miners. It can also hold physical bullion. I have over 35% of my assets in this fund and it has been a spectacular ride.
Cuimhnigh orm, a Dhia, le haghaidh maith.
