notice the use of words 'propping up'... as if this is something illegit..and gold bugs bitcoin bugs may use this and go - lookie, they are printing the dollar to worth nothing, buy gold/bitcoin now.
the public is brain washed like this.... the dumb money is way long in gold and bitcoin, and short in stocks.
if you just step back and look at the picture... if interest rate is 2-3% or lower, and stocks are yielding 6, only idiots will not borrow every dollar possible to buy stocks.
doesn't matter central banks are in the same pants with politicians or not... money is everyone's goal... you being on ET trying to make a buck is just as evil as the banks 'propping up' stocks... if that is called 'evil' at all...
the question is what do you do about it... with this interest rate SP should be at 5000 right now, what's your plan.
