Lots of variables here. Your age, risk tolerance, how much and what kind of debt you have and so on.
If you work in private sector and are not dependent on Tax Payers for your retirement, plan on saving(investing) 20-25% of your household income. That is all the time, every pay check, market up, market down. Automatic deductions are the way to go.
With Trump here for next 4 years, I'm betting on:
Cement, Heavy Equipment, Construction, Defense and Aerospace, Coal.
Coal is a long shot but I'm willing to risk a little bit. I lost almost everything I had in Coal last 2 years.
I'm also a big fan of companies paying good dividend back to share owners.
Verizon, Altria, Phillip Morris- thank you for smoking and talking on your cell while driving
Good luck.
