It concerns me when it's just so high so fast. No real reason other than it's not natural
Animal Spirits, the previous administration was so anti business that companies were fearful to make bold moves, Trump has released the power of America's economic engine. Exciting times.
Speaking factually, the market went up either 140% or 210% under Obama (depending on how you pick the start point). Assuming Trump also gets 2 terms, at the end of his 8 years the Dow will have to hit 47,800
to replicate that 140% rise, or will have to hit 61,500
to hit that same 210%. http://money.cnn.com/2017/01/10/investi ... ket-trump/
(As an aside, I personally would prefer to keep some reasonable regs and not to have to bail anyone out again).
