The situation is - if the price will go down 3.5$ per share, the future SP could be literally much more lower. It will contradict with bull trend for this particular stock. that is why 3.5 is a very strong support for NOT.

3$ is not the limit down, so may be I would think about reduce of the portfolio after 3.5. But you won't be alone in this intention. All stat. players will be with you.

Based on my experience - if the investment was done on margin - sell a half, if not - wait.
