I would expect stuff like that to happen super often but I don't think I have even heard of one real case like this.
At the risk of stating the obvious: did this realization that reality fails to match your predictions cause you to question your model or your predictions?
Yea it did but editing the original comment makes it boring.
I looked up the percentage swings caused by CEO deaths and it's actually not that big and not always a definite drop. So it wasn't as surely profitable as I thought. A murderous whitecollar sociopath probably has tons of other lower risk crimes he can commit instead. A typical insider trade would probably make him more.
Also I am not really sure hitmen exist outside of movies... I can't verify this without putting myself on some list though.
(Hello FBI! This is just morbid hypotheticals. I am not advocating serially murdering CEOs for profit)
