It's not an issue for long term believers, sb9 - PLX investors just need to be aware of the 'ramp 'em up & sell 'em down' brigade.
They do seem to have a potential issue with 'leaking' of information prior to public announcements...share price moves a fortnight in advance of their results announcements pretty much every time. It seems to settle at or close to a 'fair value' though...so not sure whether its a 'ramp and sell' or simply information leaks.
