I think Nordstrom stock went up after a negative tweet because it was seen as good publicity for the company. Trump didn't actually "threaten" to retaliate or anything, whereas for companies like Ford or GM he actually said he would impose a heavy "border tax" if they opened factories elsewhere.

perhaps further sentiment analysis could be used to determine whether the tweet implies the company can expect government action for/against them.

  Maybe a bit difficult to do so because of the limited amount of data, but we could maybe only look at the tweets with positive sentiment, in which case the stock price will likely go up. As it is good publicity for the company and Trump was positive about the stock as well.
