Well, they've finally done it.
As the following chart of the day from Bloomberg shows, as of this week, hedge funds have made "the biggest bet ever" against gold by taking Comex gold shorts to all time highs.
To their reflexive benefit, we will admit, they have managed to push the price of gold lower, not much... but it is lower (whether with the BIS' assistance or not is irrelevant). It is a different question if the price of gold is low enough to reflect such a record bearishness. But the biggest question is what happens if there is a catalyst to launch a covering rally: such as, hypothetically speaking of course, the People's Bank of China were to announce that it has in the past four years in which it provided no updates on its gold holdings (last is as of 2009), accumulated some 2000-4000 tonnes of gold.
Surely, that would be most unpleasant to all those record shorts, and the impact on the price would be most parabolic. Why, all those shorts better indeed pray there is no short squeeze now or any time in the future...
