The #1 I look at is Apple...Honestly. In 2016 they started at ~120 ish, went down to 90, and slowly climbed back up to 120 by the year's end. Recently beat analysts expectations, now it's the highest it has ever been. They have continually beat up Samsung (not to mention the note7 battery fire outrage) that forced many to switch over. Apple has been gnawing away at the market in China. Buffett bought a ton of shares to kick the year off, BOA and ML have issued a strong buy rating on Apple, with a projection of 145. This year is poised to be an interesting one with the 10yr anniversary of the iPhone, a complete design re-haul, etc. Also their dividends are attractive. I think Apple is a safe bet for the next 2-3 years, but they will have to stop relying on 2/3rds sales from the iPhone to drive growth. That ship will sail soon, and a new market will have to be tackled. Lastly, with the corporate tax rate set to be reduced, Apple will surely bring home a lot of its cash.
Next up is Amazon...Aka the next Walmart. Bezos is such a smart guy- to think they started out with book rental/purchase, e-readers, and now involved with CRM/cloud/web services, Amazon Fresh/grocery. The downside is their $845 price tag, with their last split coming in '98. Another risky attraction. If a split occurs this year, I think Amazon may be a good long-term hold. Unfortunately they miss expectations 3/4ths of the year and after everyone they get hammered...yet claw their way back. With a very high P/E, most are betting on Amazon's future rather than the short-term success, as I think its best years are ahead.
