U.S. authorities appear to be opening a new front in their efforts to battle securities fraud. The territory: financial Twitter.

Their target is @AlexDelarge6553, an allusion to the movie “Clockwork Orange” and the Twitter handle of a Maumee, Ohio-based trader named Steven Gallagher. His Twitter persona projected an image of success, posting a photo of a Tesla Model S that he claimed to have purchased with his winnings, and touting numerous thinly traded penny stocks to more than 70,000 followers.
