In my opinion, current price per share is a great price to start a new position or add to an existing position with focus on DED line.
If you have a cost per share of 50 cents or less, I think the second half of 2022 may be rewarding if you can wait that long for a payback.
Investing is risky. Investing in a small biotech start-up is even more risky. Please do your own due diligence and never invest money you might need immediately for mortgage, gasoline or food.
