Both metrics for determining future stock prices (earnings estimates and the market multiple) could now move in a very wide "band".
A wide range of outcomes implies more uncertainty, more volatility.
For example, what is the right earnings estimate for the next twelve months for the S & P 500?
"S & P 500 EPS estimates will likely be coming down at increasing rates in the weeks ahead," Nick Raich, who tracks corporate earnings at Earnings Scout, told me.
232 x 17 = 3,944 for the S & P 500, more than 150 points above where it is now.
