That's pretty self-evident surely? What he wants to achieve is the investors having the information that they're being scammed - would you be asking "what are you trying to achieve" if someone was asking about telling someone that someone had just picked their pocket?

OP wants to inform investors that they're being defrauded because he sees it as the ethical thing to do - not everything has an ulterior motive. Sounds like he's wondering if there's any possible serious unforeseen repercussions that could befall him if he goes through with it (or doesn't). Losing the job (whether through quitting or getting fired for whistleblowing) is probably a foregone conclusion.
