From the 60's all the way down to the teens.. April puts were bought and sold. Tomorrow somebody is gonna hold a wagon load of shorted shares of CLF. Nobody is buying the contracts back, so the delivered shares will be taken and then quickly covered at these astronomically low prices. Will ride ahead through monday.
Also better than expected results from BTU today may bolster CLF's share price somewhat. PERHAPS the worst is over for commodity stocks.
Not a bad time to buy if one's timeframe is a year or greater.
