This is a very long, interesting opinion piece about gold http://www.ritholtz.com/blog/2011/09/your-gold-teeth/
There are a couple paragraphs in the piece that reiterated my concerns about the GLD ETF:
For example, the SPDR Gold Trust, which is reputed to have the sixth largest inventory of gold in the world, is a Grantor Trust contractually obligated to deliver to its shareholders a dollar-equivalent gold value in the form of each day’s closing share price. Doug Hornig of Casey Research recently researched GLD by scrutinizing its prospectus and interviewing its sponsor. He concluded that ownership in it, even among investors holding more than 100,000 shares pre-approved for share/gold conversion, does not practically constitute gold ownership for shareholders. Were there to be a sudden run on physical gold that would close gold futures trading, GLD’s sponsor would not be able to open the shares for trading. All credits and debits would be reconciled in dollars. In the US any long-term profits would be taxed at the 28% tax rate on collectibles. So we think there is considerable room for disappointment among ETF holders that believe they have adequate exposure to physical gold or the performance of physical gold if and when that exposure is most needed.
We view this as a potential powder keg that will lead to sudden sponsorship of gold miner shares, analogous with the bullish argument associated with large short interest in a stock (only better). ETF shareholders are already sold on the merits of having long gold exposure. What they lack currently is the knowledge that they own a vehicle that would not provide them the benefits of gold when they need it most. We expect re-allocation from ETFs to gold miner shares as this becomes known.
Any and all thoughts are welcome.
