This market has nothing to do with Mr. Trump it is all about allocation of money. As they say it is bond market which determine stock market direction.
I think the interest rate was not this low in all previous times.
Until bank increase saving rate between 2-3 % on saving deposit market has no competitor so gyration will be short and limited in decline.
Money from Bonds are coming and parking in stock market because of rising interest rates, once rate are settled or earnings decline exit will happen and that can be long as this bull market.
Since market thinks he will hasten the policy of higher interest rate so money is moving in, rising rate decline long bonds value, it will stop some time but not very soon. Yes there will be some blips soon.
As they say Just follow the trend, do not try to lead it.
Good luck and happy trading.
