As you know I am by nature a long term holder & I was unhappy to sell my GWP.
You may well be right that something out of the ordinary is happening. Indeed I would have thought a fall or perhaps a little stagnation of the SP was much more likely than the rapid rise we have had.
I still hold a few GWP bought & paid for....around 3.000 shares bought at 62p ish....So I am naturally pleased at the rise as well as wishing success for all other holders.
