I won't be selling because I would only have sold at $15+ but I am very fearful of the future for NST. Unfortunately I am fairly heavyweight on NST after originally buying at 72c. Any fall or rise in the SP has a pronounced effect on my portfolio. I think the POG has been significantly linked to the development of a vaccine and not one but numerous vaccines seem likely to be on the market soon. Consequently many investors are piling into stocks that will benefit from the development of a vaccine and out of gold. I don't think QE is going to have the same effect as waiting for a vaccine, particularly as many countries recover economically over coming months. Once again I believe I have missed the chance to sell NST at a decent profit. I think the prospect of a merger has also already been built into the SP. I will pop the shares in the bottom drawer and wait for the next crisis to eventuate.
