Your link has an impassable wall in front of it, making it impossible to read.
Sorry about that:
"Since 2004, our gold products have provided investors a relatively efficient and liquid way to access the gold bullion market through physically-backed ETFs."
The minimum amount to redeem, is, or at least was, 100,000 shares.
OK, so it's not just a futures market. But unless you redeem 1000 ounces, you can't touch it.
I wonder how you redeem it, show up at the vault with stock certificates and trade them? That would be cool to do if you were uber rich.
You have to have a special account with the custodian, State Street Bank, and send them instructions. It takes about 3 days to settle the trade and transfer ownership of the gold to you. Once it's in your name, you can leave it in place and pay the storage costs on in, or arrange for pickup.
