Looking at the stock chart in the article, "cool reaction from investors" they mention is a downward adjustment reversing most of Wednesday gains, but still putting each company above Tuesday close. Was there another announcement Tuesday night, that set hopes high, with this one being a disappointment? What was the new information -- something about the structure of the new company perhaps? Edit: Wednesday's article: http://www.nytimes.com/2015/12/09/business/dealbook/dow-chemical-and-dupont-are-said-to-be-in-merger-talks.html?ref=topics http://www.nytimes.com/2015/12/09/business/dealbook/dow-chem... -- mentions the future split into 3 companies; does not mention the layoff details or dual headquarters though :)
