I just read a comment from an older guy (not a trader) who sold all his stocks last fall and currently have a huge excess of cash he does not know where to put. Basically, there's no yield to be found anywhere but the stock market and he's afraid to put it there now as he simply can't understand this rally.
The FED and central banks worldwide are basically forcing everyone into the stock market and have pretty much said they are willing to do whatever it takes to support the markets including buying equities/ETFs.
That's where we're at.
Makes you wonder if we're ever going to see normal rates in this lifetime.
