> this guy knew it's insider trading See, I don't know that he did at the time. I think he guessed, sold his stock before he knew whether his guess was right or not, and ended up being right. The question will be whether his guess was based on "material non-public information", but that is a much more difficult thing to determine for someone in the moment.
