Just because you see a bid and ask, doesn't mean they are from real traders/investors.
Some say that computers can trade up and back while trying to bring in real traders. If shorts don't "bite," longs (possibly LB is one and we know what firms are long) will have to start selling at this level. They'll have to pace their selling because they have so much that the stock could collapse if outstanding longs sell too many shares at one time. If one long holder wants to get ahead of others, that long could sell enough to push the stock down a few points. After that, what will longs do?
It appears that the pumps and pr garbage hitting this stock day after day shows that longs really want to exit, but want to exit some shares without pushing the stock price down too much. It happened on BTU in the 70's, RIMM above 100 and then in the 85-90 area, etc.
