This is only going to get worse due to the insane stimulus due to the coronavirus.
It is almost as if money now has so little value that losing as little of it as possible is what investors are looking for, aka negative interest rates by another name.
I wouldn’t blame the companies for this, this is a result of governments not willing to allow recessions in the early 00s, then in 08, and now. But it has serious long term effects which are hard to understand as it’s so complex.
