If these passive investment funds create a positive feedback loop for some stock prices - I don't know if that's the case - then this could be a pretty high risk. On the other hand, I would intuitively expect them to have a dampening effect on the "pump and dump" schemes that created so many bubbles. So, in a way, they could even help stabilizing the markets?
