What are you talking about? There is zero whistleblowing going on here. This is an outside investigative report funded by a hedge fund. The only link to whistleblowing is the investigators biography.
> Prior to the initial distribution of this Report on August 15, 2019, the Company also submitted this Report to the U.S. Securities and Exchange Commission’s Whistleblower Program and the U.S. Department of Justice’s FIRREA Whistleblower Program. Both or either of those submissions may generate profits for the Company independent of the financial performance of GE and/or the securities, derivatives, and other financial instruments of, and/or relating to, GE.
I don't know how the DOJ program works but SEC Whistleblowers can be awarded 10-30% of the money recovered as a result of their information.
I think he came out with the report as SEC had already started investigating GE. If he had not come out with his report he might not have been able to trade in GE stock as he would have had insider information and could be dinged for insider trading. After putting the information out in the public he can short all he wants.
