Pretty much anything that gets mentioned on social media and/or has heightened share/call activity will likely end up on this list.
Remember what the SEC & CEO of nasdaq said - they will be monitoring social media for manipulative activity. This is the start. They're not going to go after the hedge funds, they're going after the retail market. Remember, hedge fund & system manipulation is hidden, and the entire narrative across all mainstream media, c-suite execs, etc... is retail investor manipulation.
