They tell you what the market makers are pushing the stock down.. It's an urban legond that many uninformed novices blame the movements of stocks on....
Market makers usually could care less the price of a stock because they wish to only make spreads.. True MM's that take positions are creatures of the past as all brolers route real orders to a central market maker like Nite,, Ect.. I trade at E-Trade but all my orders are sent to NITE to be displayed.. NITE has no economic interest in my trades except for a tranaction fee.. hank
