No matter how many excuses are given, there's something dangerously wrong about the fact that a market maker can only buy shares of stock that exist, but can "sell" an unlimited number of shares that do not exist. Anyone given that license doesn't make a market, he manipulates the illusion of a market that in truth serves his interests first and foremost not the interests of either the real buyer or the real seller of the real stock. Ban all market makers; establish a true and transparent auction computerized.
