In your hypothetical example, a stock is going up and up, and I suspect it might be fraudulent, and you believe I have no incentive to pull my money out before the house of cards collapses?

Getting my money out is all the incentive I need! I bet plenty of Theranos investors would've loved to do exactly that. And there was no shorting involved in that company.

The question they are asking is if it’s going up & up what will ever cause it to go down?

The standard answer is the government. Which is fine but reduces a moral position to an operational one.
