As ever, it is very difficult to pinpoint exactly why gold and all precious metals fell in price. Interestingly, oil fell by even more - NYMEX crude was down by 1% and was down by more than 1.7% at one stage. The CME Group, which operates the U.S. COMEX gold futures market, said Wednesday's plunge in gold was not the consequence of a "fat finger" or a human error. The trading wasn’t even fast enough to trigger a pause on Globex, said CME. One thing that we can say for certain was that there was massive, concentrated selling as the New York stock markets opened with some 35,000 lots sold which is equivalent to 3.5 million ounces and saw the price fall from $1,735/oz to $1,711/oz between 0825 and 0830 EST. One sell order alone was believed to be 24 tonnes or 770,000 troy ounces. Incredibly there was 35% daily volume in just 60 seconds. The selling, like all peculiar, counter intuitive, sharp sell offs in recent months, was COMEX driven with COMEX contracts slammed leading to further stop loss selling. The selling may have been by speculative players on the COMEX. It may have been algo or computer trading driven or tech selling – although this is less likely. Informed commentators questioned the nature of the selling as a large institutional COMEX trading entity would normally gradually sell a position of this size in order to maximise profit.
