Two schools of thought.
1. "The new tax plan is going to lower the effective corporate rate and boost companies earnings. Repatriation will be big along with share buybacks, increased dividends, and other tools to increase EPS."
This was my first idea and I clung to it with vigor. I went in on depressed companies who would greatly benefit from this tax rate. GE in particular comes to mind. The first week of 2018 made me even more confident and I preached it like Joel Osteen.
2. "Remember, the first earnings report is going to be Q4. A number of companies are going to realize their tax bill will be much lower in 2018 and thus buy and expense as much as they can for the end of 2017. The beginning of the year is going to be poor."
My good friend, my much-smarter-than-me friend, pointed this out to me. The headlines are starting to show that the first earnings of 2018, which will be Q4 of 2017, are going to show a huge expense. GE is getting slammed, a few of the big banks say they are going to owe billions. The market looks poised to continue to increase but maybe earnings season number one will be slower than originally expected.
