Get all the concerns over political party, geopolitical events, or fiscal worry out of your minds or you will be unable to see the very simple reality in front of you. There is only one entity that is leading this nation & its not a Repubican or a Democrat. The boss in every business I've ever worked in was the one with the money writing checks!! Only entity in the USA doing this is the our . As long as they will keep printing paper real assets will continue to reprice in terms of an ever increasing medium of exchange. Thats about all you need to know so keep it simple and skip the side show on TV.
There are a lot of "experts" & even more opinions out there but very little understanding of how this whole machine really works. K.I.S.S. and remember the trend is your friend don't bet against it no matter the rational you are sold.
Regarding the current irrational exuberance:
"Markets can remain irrational a lot longer than you and I can remain solvent." from A. Gary Shilling, Forbes (1993) - (This quote was attributed to Keynes).
This would be precisely the reason you shouldn't try to call the top but instead follow the price till it shows an end to the trend. If not you will find yourself on the side line watching it go for 100's more candle maybe even thousands. The price is gonna pay you not that indicator or any other. A combination of indicators maybe a better solution.
