Provided the PM ETF is actually backed properly. The problem is that some of them lease out their gold or silver, which means that they have nothing in there for the amount of gold or silver I own in them. With China threatening to buy billions of dollars of GLD and SLV and then demand delivery, I wonder what is going to happen. If the ETFs are not able to fill their orders, what will that do to people's confidence in them?
Or time. Just give it awhile for the premiums to catch back up to the new silver prices and the premiums will rise.
