No one can care about fundamentals in QE times. If you stay out of the market just because nothing there is valuable, you will lose your money to the hidden inflation and won't be able to buy anything there when you want in.

In normal inflation you can at least buy commodities. But the US economy is organized in a way that will concentrate the money on stocks, not commodities.

You've been through this before and have the scars or have seen them on others. It is hard to explain to those who have not. Though they only need look at a historical chart.

The Fed transitioned from QE to tightening almost 5 years ago.
