MattR - I agree re. RFE behaviour. Its exactly the same with another stock I hold - NKP.
Seems to be getting sold down, sell side increases, then it just pops back up again and the sell orders are nowhere to be seen.....funny that ;)
In the past I've made the mistake of selling small quantities of both RFE and NKP into these games, only to watch the SP shoot back up again to close higher. These days I just use the opportunity to buy more !
