There are a variety of reasons to liquidate a large position. But whatever the reason, no experienced trader would take a very large position into a thin market and just dump it at the market, if they wanted to achieve some sort of reasonable economic benefit from selling that position, unless they were under duress, or had some other motive than profit. Unless of course they have a strategy to lose some in one market while making huge profits and buys in others at cheap prices, as in the case of the mining sector for example. A trader who was being paid to obtain the best value for the seller would be fired if they simply dumped a large position in the market, driving the prices realized down almost 10 percent in less than an hour. The same situation occurred at roughly the same time in the silver market, as hundreds of millions of paper ounces of silver were just dumped in the market in less than an hour, breaking the price down dramatically. Such unbridled selling triggers other selling, as the complex web of trades and relationships drive other parties to liquidate their positions and trigger stop loss orders. I have described in the past how the big trading desks use the Dr. Evil tragedy to artificially disrupt markets. Regulators are in place to prevent such things from happening. And this is the story of the economy and the governance of the US markets today. There is little rule of law, only the power of size. And it will get worse as the paper game comes closer and closer to default.

That transaction represents 1mln oz of gold.
