Markets opened higher on Friday as several banks reported strong earnings, but stocks then declined over the unpredictability surrounding President Trump, trade sanctions and the conflict in Syria.

Here are three top takes from the columnists of Real Moneyand Real Money Pro, our premium sites for Wall Street professionals and active investors: 

Jim Cramer: Micron Is Not as Cheap as It Looks

TheStreet's Jim Cramer has traded or followed Micron (MU) - Get Report for 25 years, and says, "Of all of the battleground stocks out there in tech, Micron is perhaps the most contentious. That's because when a chip stock sells at less than five times earnings your thinking is that it represents a tremendous bargain. How can it not?"

Cramer knows that "any time I express any concern about Micron I am going to get blasted for it on Twitter (TWTR) - Get Report  because it is so cheap and because, bizarrely, it is a cult stock, one that goes up and up and up until it stops and then gets real ugly...fast."

Buying the Dips and Selling the Rips

"All you really need to know about this market," observes Real Money columnist James DePorre, "is that it is trading range action. That means you can't chase strength too much and that there may be opportunities on dips. Earnings season should be fun for opportunistic traders.'

Heller's own, rather short list of restaurant favorites, "is a combination of cheap valuations, and potential takeover targets," and include four names.
