Look back over past ten years before you decide that there is a good reproducible time to buy or sell MSB. I did and found no such time. Everyone already knows the yearly earnings cycle, and ice story.
Vale just announced a reduction in its iron mining and a resulting jump in iron and steel stock prices on the news. We may be at the bottom of the iron oversupply problem. Maybe better days coming for these companies.
All the more reason for shareholders (all are short termers since the inversion in February) to sell to Teva, jettison the BOD, and rename the stupid headquarters building. Hopefully the closing will be after February 2016 (long term).
