re: the true voip winners Excellent explanation PTFE. Thanks mate.
One pie-in-sky theory on the x-trades is the first serious moves of a takeover. Plenty of cheap scrip picked up over the last months. Only 109M shares total on issue so 3M today is 3% of the company.
But taking a deep breath, I think your call on tax fiddling smells much more like reality.
Cheers.
