Good question: What would cause me to sell?
A report on a previously unknown long-term serious bad effect of anatabine consumption.
Disappearance of good effects from anatabine consumption among my friends, after long-term use.
Discovery of a substance with even better anti-inflammatory powers and equal lack of side effects.
Discovery of fraudulent description of relations with testing partners, such as PHE;
Desperate need for funds for my family or business;
Discovery of another investment with greater potential - this might cause me to re-balance my portfolio by selling a portion of my STSI. I have done this once already.
I might sell some if STSI was up a lot, and another stock with equal or greater potential was down a lot. This has happened at least once.
I may at any time sell a small portion of my holdings on a spike that I regard as irrational, especially one seemingly provoked by extreme claims made in a widely read article. In that case, I would probably buy back after the excitement had turned to disappointment.
I would sell a large portion or all if I came to think that Mullan and Campbell are not up to the task.
Unexplained steady and recurrent high-volume waves of selling over an extended period.
Probably there are other things too, many of them having nothing to do with STSI.
