Bewildered to say the least, what a dilemma, Imugene, potentially the greatest breakthrough in medicine for decades with their groundbreaking vaccines for the eradication and cures for cancer sufferers. But the share price points to a dud as far as investors are concerned. 60 cents back down to 12.5 cents So what do I ,do? Back the science and hang in for the long haul in the hope that things will turn around. Or alternatively as an investor that looks at the financial fundamentals, cut my losses enough is enough and bail out.
So much speculation surrounding this type of stock but given the science and data/results with clinical trials it's a no brainer for me.
Thanks again Ben for your very imformative post and all those who contribute to make this probably the best forum on H.C unfortunately i haven't read much of late as i am moving house at the moment so looking forward to catching up with all your comments. Cheers.
