All kinds of economic news is due out on Thursday, including jobless claims, leading indicators and money supply. Each has had its influence on the stock market at some time in the past, but none of them gets much respect these days. As such, DaBoyz will have to move stocks the old-fashioned way, manipulating them in whatever way it takes to goad shorts into covering. That’s how nearly all strong rallies begin and end, even if we’ll never see some celebrated permabear — David Stockman gets my vote — ringing the opening bell at the NYSE.
