The SP at present is being desperately manipulated it seems judging from this boards most knowledgable posters. Short answer if you want to consider it is: hold tight to your shares until this period passes and probably longterm as there is plenty of good news down the line in not too long. Easier said than done I know.
Watch the commentary on THIS BOARD for support. Personally I would do everything I could to resist taking a portion off the table just now in this period whilst the opposition is doing its worst, but that's just my course but probaly a lot of others here too.
Good luck fighting the slime. Hope this helps.
