there is some weird stuff going on with the way this stock trades lately. Its changed and i cant quite work it out. After the big drop, then it goes up 10 c one day and down 10c the next. Now there is a huge imbalance in the buy queue compared with the sell queue and looks for all the world like its shooting up again. Then low and behold drops about 6c in not long. Centre-point trades says to me algorithmic trading. Volume is up. Not sure if it is still being shorted but the report is due out next week isn't it, so it would be a brave move given its trading at a PE of about 9. Does anyone else notice changed behaviour or have any ideas?
