Comparing SP movements on different exchanges always throws up anomalies. Take Nyota Minerals for example, up 7% on AIM but no movement here on no trades. Some little fishes always slip through the net it seems (won't be a little fish for long that one...)
Back on subject I found an article on John Lewins the other day so thought I'd put up a link. You have to sign up for a free trial to read it though. Mine's expired otherwise I'd copy and paste it. Not exactly newsworthy but worth a read and can't remember it being posted before.
