No sane investor believes that this market is priced accurately. Its a Fed bubble. Trump is all about debt financing, so that shouldnt shock a soul.
If your retirement is dependent on this market, you should set a tolerance marker...and bail when it hits that marker on the way down. Ad keep moving that up with the market. Otherwise, you might get knocked down and out.
It's even worse than that! Large public pensions are now planning to borrow money to increase their holdings! (because they are underfunded!)
CalPERS' $80 Billion Leverage Plan?
Should be a good party until the music stops!
