I would expect mutual funds are much more correlated than individual stocks to the effects of monetary policy. Requiring them to trade slowly so they can't game short-term market effects from their day job makes a lot of sense. I don't fully understand the ban on individual stocks vs mutual funds though. Is that just for ease of oversight? Is ex. tesla more responsive to monetary policy than mutual funds?
