Let us, for the sake of discussion, grant the assumptions in your scenario here: the CEO "knows" the property is to lose value, and tells his pals, and other investors don't know.
My response is: So what? Must be nice to be a CEO. There's nothing fraudulent about this situation. No one is being ripped off. If certain people know certain information, fine. The market works on knowledge. Some people have more or better versions of it.
Life isn't fair. Or, better put, life in a free society isn't fair. That's supposed to be the difference between us and the socialists/liberals/democrats: We value freedom over equality; they value equality over freedom.
Freedom is very simple. It requires a quick Constitution and Bill of Rights. Equality is much more complicated. It requires reams and reams of complicated paperwork and attorneys and prosecutors to enforce laws that most of the people who are subject to them can't even understand.
I know which side I'm on.
