Index futures are off the equivalent of about 50 Dow points early Monday morning, gingerly fishing for a bottom.  It looks like buyers have control at the moment, but their nervous commitment could vanish in a trice if even a mote of unsettling news should cross the tape. At the moment, there is no news whatsoever to affect the mood of speculators — only an item atop Google’s feed concerning an impending teachers’ strike in Chicago.  Would that that were the scariest item that surfaces all day!
