Hey masscoach1. Glad to see you discovered INO, I played with them a bit ago around .50s to .70s. INO has some of the most impressive, market leading ability to revolutionize vaccine immunizations through higher efficacy, cheaper methods and an overall great approach to vaccines for serious illnesses including sexually related.
In my personal opinion, INO is very volatile at this point since much of their work is still phase I, and bio companies need to make it to stage 3 before even attempting approval, let alone some do stage 4. Fact is, they may not have enough cash to fund themselves up to that point, and may require a dilution soon. I also backed out of INO a long time ago due to heavy manipulation of daytrading. Long term, it's a phenomenal opportunity, probably a 10x bagger. But, in the interim, I may not jump in until I see a pullback, only based on my own risk/reward situation. But, of course, it still may move up and I miss an opportunity. My own theory is it's best to play it safe and not lose/regret it, than to gamble on hopes and lose what you could have kept or grown slowly but at a safer gain.
Best of luck to you either way.
