Well americans made their bed ....now they got to lay in it. So does wallstreet.The easiest excuse would be raising the capital gains tax which is coming soon. Joe Biden has already said he will raise capital gains rates. That would be the catalyst they would cite as the reason. Watch out for CNBC to say that as the reason. Truth be told, the big boys (mutual funds, brokers, banks and hedge funds) can crash the stockmarket tomorrow if they wanted to.
