It's still all about the earnings ... 

Micron Technology (MU - Get Report) is expected to report its quarterly earnings after the bell Tuesday.

What will investors be keeping a close eye on? 

Action Alerts PLUS' senior analyst Jeff Marks told research analyst Zev Fima to focus on the commentary the company gives around D-RAM pricing.

"I think what investors are going to be paying most attention to is just whatever commentary they can give on the future of D-RAM pricing as well as inventory levels, which will kind of set that tone," Marks said.

Investors will also need to factor in what's going on with the U.S. trade talks and Huawei and how that will impact Micron's guidance, Marks said.
