Sears management beleives (or has deluded themselves into beleiving, or more likely is trying to delude the share- holders into beleiving) that with a little time and investment they can recover the business. With current costs exceeding revenues, they have neither time nor funds to invest. Hence the idea that selling assets will give them time & money to fix the problem.
I agree with you. I don't think they have a clue how to solve their problems - they're still trying to figure out "how do we compete with Walmart", when the world has moved on and the real competition is the likes of Dollar General (and, of course, Amazon).
