Stock price when the opinion was issued
His firm has a 5-10% weight in gold at the moment, depending on the risk tolerance of a client. Most of it is just owning GLD, but at a level certainly no more than 10%. For good portfolio management, you want more than just 3-4 names.
You won't get hurt holding GLD, but individual mining names have run up and are primed to have some $$ taken off the table. Wouldn't be surprising for some bit of news over the next couple of months to knock the gold rally for a loop.
