It is very difficult to hide intent and the truth will always be revealed. This is because we are all sentient beings. We can feel, empathize and understand other sentient beings. That is why even though animals do not speak, we feel for them. Dog owners intuitively know if their dogs are happy or sad, sick or about the face death.
In many sense, this is very similar to stocks. Truth is intrinsic value. The reason why stocks will always revert to its intrinsic value it because that is the true value. It cannot trade way above or below its intrinsic value forever. If it is way below, someone, someday will take over and benefit from it. Conversely, if it trades above, it will fall. Or in case of an overpaid buyout, someone will suffer. The example that comes to mind is Time Warner overpaying for AOL.
This is the same with lying, dishonesty and doing things without integrity....
