The light that turned on when I read the article was that the "Commercial" is defined as a hedger, selling production before it is produced. As described, a farmer will sell crops before it is harvested in the belief that large harvests will reduce prices later and he can recieve a larger price selling now.
What became evident to me that a miner probably is not currently selling now in the belief that the price will be lower in the future. I think that current miners with their back against the wall and a rock coming is leveraging what assets they have by selling (shorting) in the futures market to obtain cash today that they can't get from bankers. Sell some of the future production now to generate cash for operations and pray for a price increase in the future to generate enough positive cash flow to pay off the shorts. The choice, die now or die in the future unless the price goes up.
I looked at the shorts (commercial/hedgers) numbers and it appears to me that the short covering of all times is almost among us.
Donkey Kong is on.
