I am curious about how that type of activity doesn't constitute insider trading? Presumably having "bad news" would constitute material nonpublic information?
(Contrary to some of the other commenters, you don't have to be an insider yourself to run afoul of the law. If the information is not public and you got someone to leak it to you, for example. https://www.investor.gov/introduction-investing/investing-ba...)
If I do some analysis and reveal some MNPI for myself, it's perfectly legal to trade on that since I do not have a fiduciary duty to any publicly traded firms.
