In the first two days in which the Fed's corporate bond program started buying ETFs, purchases totaled around USD305m. The size of the program is much larger, and it would seem very reasonable to assume fund managers will know this and proceed to frontrun the Fed.
In light of that, I'm curious if this program will result in a pareto improvement for the (financial) economy, but will set that issue aside for the purposes of this question.
Question
Is there any policy lever the Fed can attempt to use to address the moral hazard / frontrunning dilemma that seems it will be facing in the weeks/months ahead?
