Joe Granville used to talk about the "3 legs up in a bull market.... #1 = disbelief, #2 = belief (everybody understands "why"), #3 = overbelief".
IMV, we've been in #3 for quite some time... "overbelief in the Fed's money printing to solve all ills".
Could be this virus thingy ultimately reveals that money printing WON'T solve any/all problems and that the "overbelief in the Fed" has run its course... that the Fed's cache has finally worn thin... and the market will correct back to some sort of value. (More likely will "overdo that on the downside", too.)
We'll see.
FWIW....
