Stocks are priced according to sentiment for what is going to happen six to nine months down the road. Since Trump has taken office he has rolled back in the past 9 months innumerable business strangling regulations with the promise of more to come. This has caused consumer confidence and business confidence to be a 15 and 17 year highs and this in turn has caused traders to buy in anticipation of greater profits to come because in the end it is corporate profits that drive the Dow and this is what the traders and plain folks like me are seeing down the road
IMHO the implementation of Obamacare has been the largest deterrent to economic growth in the last thirty years(maybe longer). If Trump manages to correct half of the problems Obama created we could have real sustained economic growth.
Another law going into effect is electronic logging of over the road truckers. This law eliminates the old “log book” that all interstate truckers were required to carry. By going electronic, it will mean less actual driving time because they will be on he book even when they are being loaded or unloaded. This will mean that trucking costs will go up across the board. Therefore, everything shipped on a truck will go up. Your lawmakers at work.
