Assault On Gold Update — Paul Craig Roberts

"According to Andrew Maguire, on Friday, April 12, the Fed’s agents hit the market with 500 tons of naked shorts. Normally, a short is when an investor thinks the price of a stock or commodity is going to fall. He wants to sell the item in advance of the fall, pocket the money, and then buy the item back after it falls in price, thus making money on the short sale. If he doesn’t have the item, he borrows it from someone who does, putting up cash collateral equal to the current market price. Then he sells the item, waits for it to fall in price, buys it back at the lower price and returns it to the owner who returns his collateral. If enough shorts are sold, the result can be to drive down the market price.
A naked short is when the short seller does not have or borrow the item that he shorts, but sells shorts regardless. In the paper gold market, the participants are betting on gold prices and are content with the monetary payment. Therefore, generally, as participants are not interested in taking delivery of the gold, naked shorts do not need to be covered with the physical metal.

In other words, with naked shorts, no physical metal is actually sold."
