You were into a spec bio, at some significant size, with over a 3000% gain at one point and still held Long? THAT is not only NOT investing. IT is idiotic. Timing is a thoughtful metric, but unless you were Rip van Winkle the situation you describe is BLIND LUCK.
7.5 years ago the stock was under a dollar. It's now up over $8.
Nah, you are forgetting the 1:4 reverse split. 7.5 years ago the stock was over $10, and so buying then produced a loss. Sure you could cherry pick the low about 8.5 years ago, but that is really lucky timing. For most of the period from 2015-2020 the stock was in the $3-5 range, so $8 now is nothing to brag about after all these years. Dr. Missling has failed so far to creat significant value for shareholders, which makes the glacial pace of progress maddening.
