CBA back to $45-50 again soon?, page-561

I had a look at the Course of Trade on Commsec a little while ago. Market manipulation is in full swing with the robots swapping shares in tiny numbers and often brazenly identical numbers within fractions of a second. The occasional normal transaction probably represents the snapping up of a bundle of shares dislodged by a stop loss order from some luckless shareholder. That's the whole point of the robot-using manipulators. Today's results are brilliant and a credit to management. In an unrigged market the share price should have gone up or (if the market had anticipated such good results) at least not moved much. Where are the legislators or the regulators, or both?
